-To enable sign-in for users with a LinkedIn account in Azure Active Directory B2C (Azure AD B2C), you need to create an application in [LinkedIn Developers website](https://developer.linkedin.com/). For more information, see [Authorization Code Flow](/linkedin/shared/authentication/authorization-code-flow). If you don't already have a LinkedIn account, you can sign up at [https://www.linkedin.com/](https://www.linkedin.com/).

-1. By default, your LinkedIn app isn't approved for scopes related to sign in. To request a review, select the **Products** tab, and then select **Sign In with LinkedIn**. When the review is complete, the required scopes will be added to your application.

-1. Select **Identity providers**, then select **LinkedIn**.

-1. Enter a **Name**. For example, *LinkedIn*.

-1. Under the **Social identity providers**, select **LinkedIn**.

-1. From the sign-up or sign-in page, select **LinkedIn** to sign in with LinkedIn account.

-To enable users to sign in using an LinkedIn account, you need to define the account as a claims provider that Azure AD B2C can communicate with through an endpoint. The endpoint provides a set of claims that are used by Azure AD B2C to verify that a specific user has authenticated.

-The LinkedIn technical profile requires the **ExtractGivenNameFromLinkedInResponse** and **ExtractSurNameFromLinkedInResponse** claims transformations to be added to the list of ClaimsTransformations. If you don't have a **ClaimsTransformations** element defined in your file, add the parent XML elements as shown below. The claims transformations also need a new claim type defined named **nullStringClaim**.

-Add the **BuildingBlocks** element near the top of the *TrustFrameworkExtensions.xml* file. See *TrustFrameworkBase.xml* for an example.

-Your app may need to process sentences, like "Book a ticket to Paris for me", or a fragment of a sentence, like "Booking" or "Paris flight" Users also often make spelling mistakes. When planning your app, consider whether or not you want to use [Bing Spell Check](../luis-tutorial-bing-spellcheck.md) to correct user input before passing it to LUIS.

-If you do not spell check user utterances, you should train LUIS on utterances that include typos and misspellings.

-When choosing utterances, be aware that what you think are common terms or phrases might not be common for the typical user of your client application. They may not have domain experience or use different terminology. Be careful when using terms or phrases that a user would only say if they were an expert.

-You will find that even if you make efforts to create varied sentence patterns, you will still repeat some vocabulary. For example, the following utterances have similar meaning, but different terminology and phrasing:

-Each intent needs to have example utterances - at least 15. If you have an intent that does not have any example utterances, you will not be able to train LUIS. If you have an intent with one or few example utterances, LUIS may not accurately predict the intent.

-It is better to start with a few utterances, then [review the endpoint utterances](../how-to/improve-application.md) for correct intent prediction and entity extraction.

-Set your app's version settings using the LUIS portal by selecting **Manage** from the top navigation menu, in the **Application Settings** page. You can also use the [Update Version Settings API](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/versions-update-application-version-settings). See the [Reference](../luis-reference-application-settings.md) documentation for more information.

-Punctuation is a separate token in LUIS. An utterance that contains a period at the end is a separate utterance than one that does not contain a period at the end, and may get two different predictions.

-If punctuation is not normalized, LUIS doesn't ignore punctuation marks by default because some client applications may place significance on these marks. Make sure to include example utterances that use punctuation, and ones that don't, for both styles to return the same relative scores.

-Training is generally non-deterministic: utterance prediction can vary slightly across versions or apps. You can remove non-deterministic training by updating the [version settings](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/versions-update-application-version-settings) API with the UseAllTrainingData name/value pair to use all training data.

-Developers should start testing their LUIS application with real data by sending utterances to the [prediction endpoint](../luis-how-to-azure-subscription.md) URL. These utterances are used to improve the performance of the intents and entities with [Review utterances](../how-to/improve-application.md). Tests submitted using the testing pane in the LUIS portal are not sent through the endpoint, and don't contribute to active learning.

-If the word choice or word arrangement is the same, but doesn't mean the same thing, do not label it with the entity.

-description: Use this article to see frequently asked questions about LUIS, and troubleshooting information

-LUIS has little or no knowledge of the broader _NLP_ aspects, such as semantic similarity, without explicit identification in examples. For example, the following tokens (words) are three different things until they are used in similar contexts in the examples provided:

-For semantic similarity Natural Language Understanding (NLU), you can use [Conversation Language Understanding](../language-service/conversational-language-understanding/overview.md)

-Language Understand has separate resources, one type for authoring, and one type for querying the prediction endpoint, each has their own pricing. See [Resource usage and limits](luis-limits.md#resource-usage-and-limits)

-See [region support](https://azure.microsoft.com/global-infrastructure/services/?products=cognitive-services)

-LUIS stores data encrypted in an Azure data store corresponding to the region specified by the key. Data used to train the model such as entities, intents, and utterances will be saved in LUIS for the lifetime of the application. If an owner or contributor deletes the app, this data will be deleted with it. If an application hasn't been used in 90 days, it will be deleted.See [Data retention](luis-concept-data-storage.md) to know more details about data storage

-Enable or disable the use non-deterministic training option. When disabled, training will use all available data. When enabled (by default), training will use a random sample each time the app is trained, to be used as a negative for the intent. To make sure that you are getting same scores every time, make sure you train your LUIS app with all your data. See the [training article](how-to/train-test.md#change-deterministic-training-settings-using-the-version-settings-api) for more information.

-Designate a single main app. Any utterances that are suggested for review should be added to the main app, then moved back to all the other apps. This is either a full export of the app, or loading the labeled utterances from the main app to the other apps. Loading can be done from either the [LUIS](./luis-reference-regions.md) website or the authoring API for a [single utterance](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c08) or for a [batch](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c09).

-Use this article to get started with the LUIS portal, and create an authoring resource. After completing the steps in this article, you will be able to create and publish LUIS apps.

-1. To get started with LUIS, go to the [LUIS Portal](https://www.luis.ai/). If you do not already have a subscription, you will be prompted to go create a [free account](https://azure.microsoft.com/free/cognitive-services/) and return back to the portal.

-4. If your subscription lives under another tenant, you will not be able to switch tenants from the existing window. You can switch tenants by closing this window and selecting the avatar containing your initials in the top-right section of the screen. Select **Choose a different authoring resource** from the top to reopen the window.

-* **Tenant Name** - the tenant your Azure subscription is associated with. You will not be able to switch tenants from the existing window. You can switch tenants by closing this window and selecting the avatar at the top-right corner of the screen, containing your initials. Select **Choose a different authoring resource** from the top to reopen the window.

-* **Azure Resource group name** - a custom resource group name you choose in your subscription. Resource groups allow you to group Azure resources for access and management. If you currently do not have a resource group in your subscription, you will not be allowed to create one in the LUIS portal. Go to [Azure portal](https://portal.azure.com/#create/Microsoft.ResourceGroup) to create one then go to LUIS to continue the sign-in process.

-* **Location** - Choose to author your applications in one of the [three authoring locations](../luis-reference-regions.md) that are currently supported by LUIS including: West US, West Europe and East Australia

-* [Add application](https://westeurope.dev.cognitive.microsoft.com/docs/services/luis-programmatic-apis-v3-0-preview/operations/5890b47c39e2bb052c5b9c2f) - start with an empty app and create intents, utterances, and entities.

-* [Add prebuilt application](https://westeurope.dev.cognitive.microsoft.com/docs/services/luis-programmatic-apis-v3-0-preview/operations/59104e515aca2f0b48c76be5) - start with a prebuilt domain, including intents, utterances, and entities.

-1. Send an HTTP POST [request for training](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c45).

-2. Request the [training status](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c46) with an HTTP GET request.

-Use the [Version settings API](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/versions-update-application-version-settings) with the UseAllTrainingData set to *true* to turn off deterministic training.

-If you want to disable non-deterministic training for those LUIS app versions that you're building for the purpose of testing, use the [Version settings API](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/versions-update-application-version-settings) with the `UseAllTrainingData` setting set to `true`.

-* [Published package API](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/apps-packagepublishedapplicationasgzip)

-* [Not-published, trained-only package API](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/apps-packagetrainedapplicationasgzip)

-The app running in the container can't be altered. In order to change the app in the container, you need to change the app in the LUIS service using the [LUIS](https://www.luis.ai) portal or use the LUIS [authoring APIs](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c2f). Then train and/or publish, then download a new package and run the container again.

-The active version is the [version](luis-how-to-manage-versions.md) of your app that is updated when you make changes to the model using the LUIS portal. In the LUIS portal, if you want to make changes to a version that is not the active version, you need to first set that version as active.

-In LUIS, your application, or app, is a collection of machine learned models, built on the same data set, that works together to predict intents and entities for a particular scenario. Each application has a separate prediction endpoint.

-A true negative is when your app correctly predicts no match. In batch testing, a true negative occurs when your app does predict an intent or entity for an example that has not been labeled with that intent or entity.

-A contributor is not the [owner](#owner) of the app, but has the same permissions to add, edit, and delete the intents, entities, utterances. A contributor provides Azure role-based access control (Azure RBAC) to a LUIS app.

-The LUIS prediction endpoint URL is where you submit LUIS queries after the [LUIS app](#application-app) is authored and published. The endpoint URL contains the region or custom subdomain of the published app as well as the app ID. You can find the endpoint on the **[Azure resources](luis-how-to-azure-subscription.md)** page of your app, or you can get the endpoint URL from the [Get App Info](https://westus.dev.cognitive.microsoft.com/docs/services/5890b47c39e2bb17b84a55ff/operations/5890b47c39e2bb052c5b9c37) API.

-[Entities](concepts/entities.md) are words in utterances that describe information used to fulfill or identify an intent. If your entity is complex and you would like your model to identify specific parts, you can break your model into subentities. For example, you might want you model to predict an address, but also the subentities of street, city, state, and zipcode. Entities can also be used as features to models. Your response from the LUIS app will include both the predicted intents and all the entities.

-The entity will be predicted if a word in the list entity is included in the list. For example, if you have a list entity called "size" and you have the words "small, medium, large" in the list, then the size entity will be predicted for all utterances where the words "small", "medium", or "large" are used regardless of the context.

-See Prebuilt model's entry for [prebuilt entity](#prebuilt-entity)

-These hints are used in conjunction with the labels to learn how to predict new data. LUIS supports both phrase lists and using other models as features.

-Consider an example where you have a prebuilt-number feature that you have marked as required on the quantity entity for a menu ordering bot. When your bot sees `I want a bajillion large pizzas?`, bajillion will not be predicted as a quantity regardless of the context in which it appears. Bajillion is not a valid number and wonΓÇÖt be predicted by the number pre-built entity.

-An [intent](concepts/intents.md) represents a task or action the user wants to perform. It is a purpose or goal expressed in a user's input, such as booking a flight, or paying a bill. In LUIS, an utterance as a whole is classified as an intent, but parts of the utterance are extracted as entities

-In LUIS, intents within an app are mutually exclusive. This means when you add an utterance to an intent, it is considered a _positive_ example for that intent and a _negative_ example for all other intents. Negative examples should not be confused with the "None" intent, which represents utterances that are outside the scope of the app.

-Overfitting happens when the model is fixated on the specific examples and is not able to generalize well.

-A prebuilt entity is an entity LUIS provides for common types of information such as number, URL, and email. These are created based on public data. You can choose to add a prebuilt entity as a stand-alone entity, or as a feature to an entity

-This key is not the authoring key. If you have a prediction endpoint key, it should be used for any endpoint requests instead of the authoring key. You can see your current prediction key inside the endpoint URL at the bottom of Azure resources page in LUIS website. It is the value of the subscription-key name/value pair.

-The [score](luis-concept-prediction-score.md) is a number from 0 and 1 that is a measure of how confident the system is that a particular input utterance matches a particular intent. A score closer to 1 means the system is very confident about its output and a score closer to 0 means the system is confident that the input does not match a particular output. Scores in the middle mean the system is very unsure of how to make the decision.

-|Small| the little one, 8 ounce|

-|Medium| regular, 12 ounce|

-|Large| big, 16 ounce|

-|Xtra large| the biggest one, 24 ounce|

-The model will return the normalized value for the entity when any of synonyms are seen in the input.

-The endpoint includes [timezoneOffset](luis-concept-data-alteration.md#change-time-zone-of-prebuilt-datetimev2-entity). This is the number in minutes you want to add or remove from the datetimeV2 prebuilt entity. For example, if the utterance is "what time is it now?", the datetimeV2 returned is the current time for the client request. If your client request is coming from a bot or other application that is not the same as your bot's user, you should pass in the offset between the bot and the user.

-|`RMT33W`|1|A record locator number. It may have numbers and letters, but does not have any punctuation.|

-Training errors are predictions on your training data that do not match their labels.

-An [utterance](concepts/utterances.md) is user input that is short text representative of a sentence in a conversation. It is a natural language phrase such as "book 2 tickets to Seattle next Tuesday". Example utterances are added to train the model and the model predicts on new utterance at runtime

-You can use the [v3.0-preview LUIS Programmatic APIs](https://westus.dev.cognitive.microsoft.com/docs/services/luis-programmatic-apis-v3-0-preview/operations/5890b47c39e2bb052c5b9c2f) to manage authoring resources.

-LUIS authoring regions are supported by the LUIS portal. To publish a LUIS app to more than one region, you need at least one predection key per region.

-A public app is published in all regions so that a user with a supported predection resource can access the app in all regions.

-When you first create our LUIS application, you are required to choose an [authoring region](#luis-authoring-regions). To use the application in runtime, you are required to create a resource in a publishing region.

-Single data residency means that the data does not leave the boundaries of the region.

-You use the [Face - Detect](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236) API to detect faces in an image. To get started using the REST API or a client SDK, follow a [quickstart](./quickstarts-sdk/identity-client-library.md). Or, for a more in-depth guide, see [Call the detect API](./how-to/identity-detect-faces.md).

-The face ID is a unique identifier string for each detected face in an image. Face ID requires limited access approval, which you can apply for by filling out the [intake form](https://aka.ms/facerecognition). For more information, see the Face [limited access page](/legal/cognitive-services/computer-vision/limited-access-identity?context=%2Fazure%2Fcognitive-services%2Fcomputer-vision%2Fcontext%2Fcontext). You can request a face ID in your [Face - Detect](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236) API call.

-Attributes are a set of features that can optionally be detected by the [Face - Detect](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236) API. The following attributes can be detected:

-You need to create a [PersonGroup](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395244) or [LargePersonGroup](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/599acdee6ac60f11b48b5a9d) to store the set of people to match against. PersonGroups hold [Person](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523c) objects, which each represent an individual person and hold a set of face data belonging to that person.

-The [Train](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395249) operation prepares the data set to be used in face data comparisons.

-The [Identify](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395239) operation takes one or several source face IDs (from a DetectedFace or PersistedFace object) and a PersonGroup or LargePersonGroup. It returns a list of the Person objects that each source face might belong to. Returned Person objects are wrapped as Candidate objects, which have a prediction confidence value.

-The [Verify](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523a) operation takes a single face ID (from a DetectedFace or PersistedFace object) and a Person object. It determines whether the face belongs to that same person. Verification is one-to-one matching and can be used as a final check on the results from the Identify API call. However, you can optionally pass in the PersonGroup to which the candidate Person belongs to improve the API performance.

-The Find Similar operation does face matching between a target face and a set of candidate faces, finding a smaller set of faces that look similar to the target face. This is useful for doing a face search by image.

-The code snippets in this guide are written in C# by using the Azure AI Face client library. The same functionality is available through the [REST API](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395236).

-The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the [Face - Detect] API on a variety of images, especially images of many faces or of faces that are difficult to see, using each detection model. Pay attention to the number of faces that each model returns.

-When you use the [Face - Detect] API, you can assign the model version with the `detectionModel` parameter. The available values are:

-A request URL for the [Face - Detect] REST API will look like this:

-The Face service can extract face data from an image and associate it with a **Person** object through the [PersonGroup Person - Add Face](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523b) API. In this API call, you can specify the detection model in the same way as in [Face - Detect].

-> You don't need to use the same detection model for all faces in a **Person** object, and you don't need to use the same detection model when detecting new faces to compare with a **Person** object (in the [Face - Identify] API, for example).

-When using the [Face - Detect] API, assign the model version with the `recognitionModel` parameter. The available values are:

-Optionally, you can specify the _returnRecognitionModel_ parameter (default **false**) to indicate whether _recognitionModel_ should be returned in response. So, a request URL for the [Face - Detect] REST API will look like this:

-The Face service can extract face data from an image and associate it with a **Person** object (through the [Add face](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523b) API call, for example), and multiple **Person** objects can be stored together in a **PersonGroup**. Then, a new face can be compared against a **PersonGroup** (with the [Face - Identify] call), and the matching person within that group can be identified.

-A **PersonGroup** should have one unique recognition model for all of the **Person**s, and you can specify this using the `recognitionModel` parameter when you create the group ([PersonGroup - Create] or [LargePersonGroup - Create]). If you don't specify this parameter, the original `recognition_01` model is used. A group will always use the recognition model it was created with, and new faces will become associated with this model when they're added to it. This can't be changed after a group's creation. To see what model a **PersonGroup** is configured with, use the [PersonGroup - Get] API with the _returnRecognitionModel_ parameter set as **true**.

-Correspondingly, you need to specify which model to use when detecting faces to compare against this **PersonGroup** (through the [Face - Detect] API). The model you use should always be consistent with the **PersonGroup**'s configuration; otherwise, the operation will fail due to incompatible models.

-There is no change in the [Face - Identify] API; you only need to specify the model version in detection.

-You can also specify a recognition model for similarity search. You can assign the model version with `recognitionModel` when creating the **FaceList** with [FaceList - Create] API or [LargeFaceList - Create]. If you don't specify this parameter, the `recognition_01` model is used by default. A **FaceList** will always use the recognition model it was created with, and new faces will become associated with this model when they're added to the list; you can't change this after creation. To see what model a **FaceList** is configured with, use the [FaceList - Get] API with the _returnRecognitionModel_ parameter set as **true**.

-This code creates a **FaceList** called `My face collection`, using the _recognition_04_ model for feature extraction. When you search this **FaceList** for similar faces to a new detected face, that face must have been detected ([Face - Detect]) using the _recognition_04_ model. As in the previous section, the model needs to be consistent.

-There is no change in the [Face - Find Similar] API; you only specify the model version in detection.

-The [Face - Verify] API checks whether two faces belong to the same person. There is no change in the Verify API with regard to recognition models, but you can only compare faces that were detected with the same model.

-1. Train your **PersonGroup**s using the PersonGroup - Train API.

-1. Test with Face - Identify on all four **PersonGroup**s and compare the results.

-The service supports two working modes, **matchPerson** and **matchFace**. The **matchPerson** mode returns similar faces after filtering for the same person by using the [Verify API](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523a). The **matchFace** mode ignores the same-person filter. It returns a list of similar candidate faces that may or may not belong to the same person.

-To find four similar faces, the **matchPerson** mode returns A and B, which show the same person as the target face. The **matchFace** mode returns A, B, C, and D, which is exactly four candidates, even if some aren't the same person as the target or have low similarity. For more information, see the [Facial recognition](concept-face-recognition.md) concepts guide or the [Find Similar API](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395237) reference documentation.

-All of the faces in a returned group are likely to belong to the same person, but there can be several different groups for a single person. Those groups are differentiated by another factor, such as expression, for example. For more information, see the [Facial recognition](concept-face-recognition.md) concepts guide or the [Group API](https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f30395238) reference documentation.

-> "Task": "Summarization",

-> "Text": "Ms Johnson has been in the hospital after experiencing a stroke.",

-> "GroundingSources": ["Our patient, Ms. Johnson, presented with persistent fatigue, unexplained weight loss, and frequent night sweats. After a series of tests, she was diagnosed with HodgkinΓÇÖs lymphoma, a type of cancer that affects the lymphatic system. The diagnosis was confirmed through a lymph node biopsy revealing the presence of Reed-Sternberg cells, a characteristic of this disease. She was further staged using PET-CT scans. Her treatment plan includes chemotherapy and possibly radiation therapy, depending on her response to treatment. The medical team remains optimistic about her prognosis given the high cure rate of HodgkinΓÇÖs lymphoma."],

-| **reasoning** | (Optional) Specifies whether to use the reasoning feature. The default value is `false`. If `true`, you need to bring your own Azure OpenAI resources to provide an explanation. Be careful: using reasoning increases the processing time and incurs extra fees.| Boolean |

-| **confidenceScore** | The confidence value of the _ungrounded_ designation. The score ranges from 0 to 1. | Float |

-| -**`Text`** | The specific text that is ungrounded. | String |

-In order to use your Azure OpenAI resource to enable the reasoning feature, use Managed Identity to allow your Content Safety resource to access the Azure OpenAI resource:

-In your request to the Groundedness detection API, set the `"Reasoning"` body parameter to `true`, and provide the other needed parameters:

-| **llmResource** | (Optional) If you want to use your own Azure OpenAI resources instead of our default GPT resources, add this field and include the subfields for the resources used. If you don't want to use your own resources, remove this field from the input. | String |

-| - `resourceType `| Specifies the type of resource being used. Currently it only allows `AzureOpenAI`. | Enum|

- "utF8": 0,

- "utF16": 0,

- "utF8": 8,

- "utF16": 8,

-| **confidenceScore** | The confidence value of the _ungrounded_ designation. The score ranges from 0 to 1. | Float |

-| -**`Text`** | The specific text that is ungrounded. | String |

-| -**`Reason`** | Offers explanations for detected ungroundedness. | String |

-1. **Document type confidence score**: The document type confidence is an indicator of closely the analyzed document resembleds documents in the training dataset. When the document type confidence is low, this is indicative of template or structural variations in the analyzed document. To improve the document type confidence, label a document with that specific variation and add it to your training dataset. Once the model is re-trained, it should be better equipped to handl that class of variations.

-2. **Field level confidence**: Each labled field extracted has an associated confidence score. This score reflects the model's confidence on the position of the value extracted. While evaluating the confidence you should also look at the underlying extraction confidence to generate a comprehensive confidence for the extracted result. Evaluate the OCR results for text extraction or selection marks depending on the field type to generate a composite confidence score for the field.

-3. **Word confidence score** Each word extracted within the document has an associated confidence score. The score represents the confidence of the transcription. The pages array contains an array of words, each word has an associated span and confidence. Spans from the custom field extracted values will match the spans of the extracted words.

-4. **Selection mark confidence score**: The pages array also contains an array of selection marks, each selection mark has a confidence score representing the confidence of the seletion mark and selection state detection. When a labeled field is a selection mark, the custom field selection confidence combined with the selection mark confidence is an accurate representation of the overall confidence that the field was extracted correctly.

-With the addition of table, row and cell confidence with the ```2024-02-29-preview``` API, here are some common questions that should help with interpreting the table, row and cell scores:

-Before requesting a quota increase (where applicable), ensure that it's necessary. Document Intelligence service uses autoscaling to bring the required computational resources in "on-demand" and at the same time to keep the customer costs low, deprovision unused resources by not maintaining an excessive amount of hardware capacity.

-Azure Logic Apps is a cloud-based platform that can be used to automate workflows without writing a single line of code. The platform enables you to easily integrate Microsoft and third-party applications with your apps, data, services, and systems. A Logic App is the Azure resource you create when you want to develop a workflow. Here are a few examples of what you can do with a Logic App:

-Let's quickly review what we've done before we test our flow:

-Now that we've created the flow, the last thing to do is to test it and make sure that we're getting the expected behavior.

-Congratulations! You've officially completed this tutorial.

-As you use this API in your application, see the [reference documentation](/rest/api/language/2023-04-01/conversation-analysis-runtime) for additional information.

-Within a few minutes, the target will be assigned the selected role at the selected scope. For help with these steps, see [Assign Azure roles using the Azure portal](../../../role-based-access-control/role-assignments-portal.md).

- *[Language Runtime CLU APIs](/rest/api/language/2023-04-01/conversation-analysis-runtime)

-When you send asynchronous requests, you will incur charges based on number of text records you include in your request, for each feature use. For example, if you send a text record for sentiment analysis and NER, it will be counted as sending two text records, and you will be charged for both according to your [pricing tier](https://azure.microsoft.com/pricing/details/cognitive-services/language-service/).

-To submit an asynchronous job, review the [reference documentation](/rest/api/language/2023-04-01/text-analysis-runtime/submit-job) for the JSON body you'll send in your request.

-A successful call will return a 202 response code. The `operation-location` in the response header will be the URL you will use to retrieve the API results. The value will look similar to the following URL:

-To [get the status and retrieve the results](/rest/api/language/2023-04-01/text-analysis-runtime/job-status) of the request, send a GET request to the URL you received in the `operation-location` header from the previous API response. Remember to include your key in the `Ocp-Apim-Subscription-Key`. The response will include the results of your API call.

-Starting in version `2022-07-01-preview` of the REST API, you can request automatic [language detection](../language-detection/overview.md) on your documents. By setting the `language` parameter to `auto`, the detected language code of the text will be returned as a language value in the response. This language detection will not incur extra charges to your Language resource.

-You can query the deployment programmatically using the [Prediction API](https://aka.ms/ct-runtime-api) or through the client libraries (Azure SDK).

-You can use NER resolutions to implement actions or retrieve further information. For example, your service can extract datetime entities to extract dates and times that will be provided to a meeting scheduling system.

-Use this article to get an overview of the new API changes starting from `2023-04-15-preview` version. This API change mainly introduces two new concepts (`entity types` and `entity tags`) replacing the `category` and `subcategory` fields in the current Generally Available API.

-The changes introduce better flexibility for named entity recognition, including:

-* More granular entity recognition through introducing the tags list where an entity could be tagged by more than one entity tag.

-Named Entity Recognition (NER) is one of the features offered by [Azure AI Language](../overview.md), a collection of machine learning and AI algorithms in the cloud for developing intelligent applications that involve written language. The NER feature can identify and categorize entities in unstructured text. For example: people, places, organizations, and quantities.

-This article is to help you understand the support lifecycle for the Azure OpenAI API previews. New preview APIs target a monthly release cadence. After July 1, 2024, the latest three preview APIs will remain supported while older APIs will no longer be supported unless support is explictly indicated.

-Azure OpenAI API version [2024-03-01-preview](https://github.com/Azure/azure-rest-api-specs/blob/main/specification/cognitiveservices/data-plane/AzureOpenAI/inference/preview/2024-03-01-preview/inference.json)

-This version contains support for all the latest Azure OpenAI features including:

-Assistants use the [same API for file upload as fine-tuning](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP). When uploading a file you have to specify an appropriate value for the [purpose parameter](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP#purpose).

-Annotations are currently available in the GA API version `2024-02-01` and in all preview versions starting from `2023-06-01-preview` for Completions and Chat Completions (GPT models). The following code snippet shows how to use annotations:

-> When content filtering is triggered for a prompt and a `"status": 400` is received as part of the response there may be a charge for this request as the prompt was evaluated by the service. [Charges will also occur](https://azure.microsoft.com/pricing/details/cognitive-services/openai-service/) when a `"status":200` is received with `"finish_reason": "content_filter"`. In this case the prompt did not have any issues, but the completion generated by the model was detected to violate the content filtering rules which results in the completion being filtered.

-| [GPT-4](#gpt-4-and-gpt-4-turbo-preview) | A set of models that improve on GPT-3.5 and can understand and generate natural language and code. |

-## GPT-4 and GPT-4 Turbo Preview

- GPT-4 is a large multimodal model (accepting text or image inputs and generating text) that can solve difficult problems with greater accuracy than any of OpenAI's previous models. Like GPT-3.5 Turbo, GPT-4 is optimized for chat and works well for traditional completions tasks. Use the Chat Completions API to use GPT-4. To learn more about how to interact with GPT-4 and the Chat Completions API check out our [in-depth how-to](../how-to/chatgpt.md).

- GPT-4 Turbo with Vision is the version of GPT-4 that accepts image inputs. It is available as the `vision-preview` model of `gpt-4`.

-You can see the token context length supported by each model in the [model summary table](#model-summary-table-and-region-availability).

-> This article only covers model/region availability that applies to all Azure OpenAI customers with deployment types of **Standard**. Some select customers have access to model/region combinations that are not listed in the unified table below. These tables also do not apply to customers using only **Provisioned** deployment types which have their own unique model/region availability matrix. For more information on **Provisioned** deployments refer to our [Provisioned guidance](./provisioned-throughput.md).

-### GPT-4 and GPT-4 Turbo Preview models

-GPT-4, GPT-4-32k, and GPT-4 Turbo with Vision are now available to all Azure OpenAI Service customers. Availability varies by region. If you don't see GPT-4 in your region, please check back later.

-These models can only be used with the Chat Completion API.

-GPT-4 version 0314 is the first version of the model released. Version 0613 is the second version of the model and adds function calling support.

-See [model versions](../concepts/model-versions.md) to learn about how Azure OpenAI Service handles model version upgrades, and [working with models](../how-to/working-with-models.md) to learn how to view and configure the model version settings of your GPT-4 deployments.

-> Version `0314` of `gpt-4` and `gpt-4-32k` will be retired no earlier than July 5, 2024. Version `0613` of `gpt-4` and `gpt-4-32k` will be retired no earlier than September 30, 2024. See [model updates](../how-to/working-with-models.md#model-updates) for model upgrade behavior.

-GPT-4 version 0125-preview is an updated version of the GPT-4 Turbo preview previously released as version 1106-preview. GPT-4 version 0125-preview completes tasks such as code generation more completely compared to gpt-4-1106-preview. Because of this, depending on the task, customers may find that GPT-4-0125-preview generates more output compared to the gpt-4-1106-preview. We recommend customers compare the outputs of the new model. GPT-4-0125-preview also addresses bugs in gpt-4-1106-preview with UTF-8 handling for non-English languages.

-> [!IMPORTANT]

->

-> - `gpt-4` versions 1106-Preview and 0125-Preview will be upgraded with a stable version of `gpt-4` in the future. The deployment upgrade of `gpt-4` 1106-Preview to `gpt-4` 0125-Preview scheduled for March 8, 2024 is no longer taking place. Deployments of `gpt-4` versions 1106-Preview and 0125-Preview set to "Auto-update to default" and "Upgrade when expired" will start to be upgraded after the stable version is released. For each deployment, a model version upgrade takes place with no interruption in service for API calls. Upgrades are staged by region and the full upgrade process is expected to take 2 weeks. Deployments of `gpt-4` versions 1106-Preview and 0125-Preview set to "No autoupgrade" will not be upgraded and will stop operating when the preview version is upgraded in the region.

-Provisioned throughput quota represents a specific amount of total throughput you can deploy. Quota in the Azure OpenAI Service is managed at the subscription level. All Azure OpenAI resources within the subscription share this quota.

-Quota is specified in Provisioned throughput units and is specific to a (deployment type, model, region) triplet. Quota isn't interchangeable. Meaning you can't use quota for GPT-4 to deploy GPT-35-turbo. You can raise a support request to move quota across deployment types, models, or regions but the swap isn't guaranteed.

-### How utilization enforcement works

-Provisioned deployments provide you with an allocated amount of model processing capacity to run a given model. The `Provisioned-Managed Utilization` metric in Azure Monitor measures a given deployments utilization on 1-minute increments. Provisioned-Managed deployments are optimized to ensure that accepted calls are processed with a consistent model processing time (actual end-to-end latency is dependent on a call's characteristics). When the workload exceeds the allocated PTU capacity, the service returns a 429 HTTP status code until the utilization drops down below 100%.

-We use a variation of the leaky bucket algorithm to maintain utilization below 100% while allowing some burstiness in the traffic. The high-level logic is as follows:

-The number of concurrent calls you can achieve depends on each call's shape (prompt size, max_token parameter, etc). The service will continue to accept calls until the utilization reach 100%. To determine the approximate number of concurrent calls you can model out the maximum requests per minute for a particular call shape in the [capacity calculator](https://oai.azure.com/portal/calculator). If the system generates less than the number of samplings tokens like max_token, it will accept more requests.

-## To Avoid Fabrication or Ungrounded Content

-* If you're converting data from an unsupported format into a supported format, make sure the conversion:

- This affects the quality of the model response.

-You need to connect to a data source to upload your data. When you want to use your data to chat with an Azure OpenAI model, your data is chunked in a search index so that relevant data can be found based on user queries. For some data sources such as uploading files from your local machine (preview) or data contained in a blob storage account (preview), Azure AI Search is used.

-When you choose the following data sources, your data is ingested into an Azure AI Search index.

-|Data source | Description |

-Azure OpenAI On Your Data has intelligent search enabled for your data. Semantic search is enabled by default if you have both semantic search and keyword search. If you have embedding models, intelligent search will default to hybrid + semantic search.

-If you're using your own index, you will be prompted in the Azure OpenAI Studio to define which fields you want to map for answering questions when you add your data source. You can provide multiple fields for *Content data*, and should include all fields that have text pertaining to your use case.

-Mapping these fields correctly helps ensure the model has better response and citation quality. You can additionally configure this [in the API](../references/on-your-data.md) using the `fieldsMapping` parameter.

-# [Azure Cosmos DB for MongoDB vCore](#tab/mongo-db)

-* [Azure Cosmos DB for MongoDB vCore](/azure/cosmos-db/mongodb/vcore/introduction) account

-* Only Azure Cosmos DB for MongoDB vCore is supported.

-* The search type is limited to [Azure Cosmos DB for MongoDB vCore vector search](/azure/cosmos-db/mongodb/vcore/vector-search) with an Azure OpenAI embedding model.

-Use the script provided on [GitHub](https://github.com/microsoft/sample-app-aoai-chatGPT/blob/feature/2023-9/scripts/cosmos_mongo_vcore_data_preparation.py) to prepare your data.

-<!--### Add your data source in Azure OpenAI Studio

-To add Azure Cosmos DB for MongoDB vCore as a data source, you will need an existing Azure Cosmos DB for MongoDB vCore index containing your data, and a deployed Azure OpenAI Ada embeddings model that will be used for vector search.

-1. In the [Azure OpenAI portal](https://oai.azure.com/portal) chat playground, select **Add your data**. In the panel that appears, select **Azure Cosmos DB for MongoDB vCore** as the data source.

-1. Select your Azure subscription and database account, then connect to your Azure Cosmos DB account by providing your Azure Cosmos DB account username and password.

-

-1. **Select Database**. In the dropdown menus, select the database name, database collection, and index name that you want to use as your data source. Select the embedding model deployment you would like to use for vector search on this data source, and acknowledge that you will incur charges for using vector search. Then select **Next**.

- :::image type="content" source="../media/use-your-data/select-mongo-database.png" alt-text="A screenshot showing the screen for adding Mongo DB settings in Azure OpenAI Studio." lightbox="../media/use-your-data/select-mongo-database.png":::

-When you add your Azure Cosmos DB for MongoDB vCore data source, you can specify data fields to properly map your data for retrieval.

-* Content data (required): One or more provided fields that will be used to ground the model on your data. For multiple fields, separate the values with commas, with no spaces.

-> * Automatic index refreshing is supported for Azure Blob Storage only.

-> * If a document is deleted from input blob container, the corresponding chunk index records won't be removed by the scheduled refresh.

-After the data ingestion is set to a cadence other than once, Azure AI Search indexers will be created with a schedule equivalent to `0.5 * the cadence specified`. This means that at the specified cadence, the indexers will pull the documents that were added or modified from the storage container, reprocess and index them. This ensures that the updated data gets preprocessed and indexed in the final index at the desired cadence automatically. To update your data, you only need to upload the additional documents from the Azure portal. From the portal, select **Storage Account** > **Containers**. Select the name of the original container, then **Upload**. The index will pick up the files automatically after the scheduled refresh period. The intermediate assets created in the Azure AI Search resource will not be cleaned up after ingestion to allow for future runs. These assets are:

-Using Azure OpenAI Studio, you can upload files from your machine to try Azure OpenAI On Your Data, and optionally creating a new Azure Blob Storage account and Azure AI Search resource. The service then stores the files to an Azure storage container and performs ingestion from the container. You can use the [quickstart](../use-your-data-quickstart.md) article to learn how to use this data source option.

-A small chunk size like 256 produces more granular chunks. This size also means the model will utilize fewer tokens to generate its output (unless the number of retrieved documents is very high), potentially costing less. Smaller chunks also mean the model does not have to process and interpret long sections of text, reducing noise and distraction. This granularity and focus however pose a potential problem. Important information might not be among the top retrieved chunks, especially if the number of retrieved documents is set to a low value like 3.

-Azure OpenAI On Your Data works by sending instructions to a large language model in the form of prompts to answer user queries using your data. If there is a certain behavior that is critical to the application, you can repeat the behavior in system message to increase its accuracy. For example, to guide the model to only answer from documents, you can add "*Please answer using retrieved documents only, and without using your knowledge. Please generate citations to retrieved documents for every claim in your answer. If the user question cannot be answered using retrieved documents, please explain the reasoning behind why documents are relevant to user queries. In any case, do not answer using your own knowledge."*.

-> The system message is used to modify how GPT assistant responds to a user question based on retrieved documentation. It does not affect the retrieval process. If you'd like to provide instructions for the retrieval process, it is better to include them in the questions.

-* For processing the intent: The token estimate for the *intent prompt* includes those for the user question, conversation history and the instructions sent to the model for intent generation.

-* For generating the response: The token estimate for the *generation prompt* includes those for the user question, conversation history, the retrieved list of document chunks, role information and the instructions sent to it for generation.

-### Failed ingestion jobs

-To troubleshoot a failed job, always look out for errors or warnings specified either in the API response or Azure OpenAI studio. Here are some of the common errors and warnings:

-*An index with the name X in service Y could not be created. Index quota has been exceeded for this service. You must either delete unused indexes first, add a delay between index creation requests, or upgrade the service for higher limits.*

-*Could not execute skill because the Web API request failed*

-*Could not execute skill because Web API skill response is invalid*

-description: Learn how to create helpful AI Assistants with tools like Code Interpreter

-Azure OpenAI Assistants (Preview) allows you to create AI assistants tailored to your needs through custom instructions and augmented by advanced tools like code interpreter, and custom functions. In this article we'll provide an in-depth walkthrough of getting started with the Assistants API.

-Now let's create a thread

-A thread is essentially the record of the conversation session between the assistant and the user. It's similar to the messages array/list in a typical chat completions API call. One of the key differences, is unlike a chat completions messages array, you don't need to track tokens with each call to make sure that you're remaining below the context length of the model. Threads abstract away this management detail and will compress the thread history as needed in order to allow the conversation to continue. The ability for threads to accomplish this with larger conversations is enhanced when using the latest models, which have larger context lengths as well as support for the latest features.

-Next create the first user question to add to the thread

-# Learn how to work with the GPT-35-Turbo and GPT-4 models

-The GPT-35-Turbo and GPT-4 models are language models that are optimized for conversational interfaces. The models behave differently than the older GPT-3 models. Previous models were text-in and text-out, meaning they accepted a prompt string and returned a completion to append to the prompt. However, the GPT-35-Turbo and GPT-4 models are conversation-in and message-out. The models expect input formatted in a specific chat-like transcript format, and return a completion that represents a model-written message in the chat. While this format was designed specifically for multi-turn conversations, you'll find it can also work well for non-chat scenarios too.

-In Azure OpenAI there are two different options for interacting with these type of models:

-The Chat Completion API is a new dedicated API for interacting with the GPT-35-Turbo and GPT-4 models. This API is the preferred method for accessing these models. **It is also the only way to access the new GPT-4 models**.

-ChatML uses the same [completion API](../reference.md#completions) that you use for other models like text-davinci-002, it requires a unique token based prompt format known as Chat Markup Language (ChatML). This provides lower level access than the dedicated Chat Completion API, but also requires additional input validation, only supports gpt-35-turbo models, and **the underlying format is more likely to change over time**.

-This article walks you through getting started with the GPT-35-Turbo and GPT-4 models. It's important to use the techniques described here to get the best results. If you try to interact with the models the same way you did with the older model series, the models will often be verbose and provide less useful responses.

-Assistants use the [same API for file upload as fine-tuning](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP). When uploading a file you have to specify an appropriate value for the [purpose parameter](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP#purpose).

-* [File Upload API reference](/rest/api/azureopenai/files/upload?view=rest-azureopenai-2024-02-15-preview&tabs=HTTP)

-> All customers have the ability to modify the content filters to be stricter (for example, to filter content at lower severity levels than the default). Approval is required for turning the content filters partially or fully off. Managed customers only may apply for full content filtering control via this form: [Azure OpenAI Limited Access Review: Modified Content Filters](https://ncv.microsoft.com/uEfCgnITdR).

-You must also include the `enhancements` and `data_sources` objects. `enhancements` represents the specific Vision enhancement features requested in the chat. It has a `grounding` and `ocr` property, which both have a boolean `enabled` property. Use these to request the OCR service and/or the object detection/grounding service. `data_sources` represents the Computer Vision resource data that's needed for Vision enhancement. It has a `type` property which should be `"AzureComputerVision"` and a `parameters` property. Set the `endpoint` and `key` to the endpoint URL and access key of your Computer Vision resource.

- "data_sources": [

-You call the same method as in the previous step, but include the new *extra_body* parameter. It contains the `enhancements` and `data_sources` fields.

-`data_sources` represents the Computer Vision resource data that's needed for Vision enhancement. It has a `type` field which should be `"AzureComputerVision"` and a `parameters` field. Set the `endpoint` and `key` to the endpoint URL and access key of your Computer Vision resource. R

-In the beginning, there was nothingness, a vast expanse of empty space, a blank canvas waiting to be painted with the wonders of existence. Then, approximately 13.8 billion years ago, something extraordinary happened, an event that would mark the birth of the universe ΓÇô the Big Bang.

-The Big Bang was not an explosion in the conventional sense but rather an expansion, an incredibly rapid stretching of space that took place everywhere in the universe at once. In just a fraction of a second, the universe grew from smaller than a single atom to an incomprehensibly large expanse.

-In these first moments, the universe was unimaginably hot and dense, filled with a seething soup of subatomic particles and radiant energy. As the universe expanded, it began to cool, allowing the first particles to form. Protons and neutrons came together to create the first simple atomic nuclei in a process known as nucleosynthesis.

-For hundreds of thousands of years, the universe continued to cool and expand

-Once upon a time, in the vast expanse of nothingness, there was a moment that would come to define everything. This moment, a tiny fraction of a second that would be forever known as the Big Bang, marked the birth of the universe as we know it.

-Before this moment, there was no space, no time, just an infinitesimally small point of pure energy, a singularity where all the laws of physics as we understand them did not apply. Then, suddenly, this singular point began to expand at an incredible rate. In a cosmic symphony of creation, matter, energy, space, and time all burst forth into existence.

-The universe was a hot, dense soup of particles, a place of unimaginable heat and pressure. It was in this crucible of creation that the simplest elements were formed. Hydrogen and helium, the building blocks of the cosmos, came into being.

-Once upon a time, in the vast expanse of nothingness, there was a singularity, an infinitely small and infinitely dense point where all the mass and energy of what would become the universe were concentrated. This singularity was like a tightly wound cosmic spring holding within it the potential of everything that would ever exist.

-Then, approximately 13.8 billion years ago, something extraordinary happened. This singularity began to expand in an event we now call the Big Bang. In just a fraction of a second, the universe grew exponentially during a period known as cosmic inflation. It was like a symphony's first resounding chord, setting the stage for a cosmic performance that would unfold over billions of years.

-As the universe expanded and cooled, the fundamental forces of nature that we know today ΓÇô gravity, electromagnetism, and the strong and weak nuclear forces ΓÇô began to take shape. Particles of matter were created and began to clump together under the force of gravity, forming the first atoms

These clouds, driven by the force of gravity, began to collapse in on themselves, creating the first stars. The stars were crucibles of nuclear fusion, forging heavier elements like carbon, nitrogen, and oxygen

-By using the same `seed` parameter of 42 for each of our three requests we're able to produce much more consistent (in this case identical) results.

-# How to switch between OpenAI and Azure OpenAI endpoints with Python

-While OpenAI and Azure OpenAI Service rely on a [common Python client library](https://github.com/openai/openai-python), there are small changes you need to make to your code in order to swap back and forth between endpoints. This article walks you through the common changes and differences you'll experience when working across OpenAI and Azure OpenAI.

-This article only shows examples with the new OpenAI Python 1.x API library. For information on migrating from `0.28.1` to `1.x` refer to our [migration guide](./migration.md).

-## Authentication

-We recommend using environment variables. If you haven't done this before our [Python quickstarts](../quickstart.md) walk you through this configuration.

-## Keyword argument for model

-OpenAI uses the `model` keyword argument to specify what model to use. Azure OpenAI has the concept of unique model [deployments](create-resource.md?pivots=web-portal#deploy-a-model). When using Azure OpenAI `model` should refer to the underlying deployment name you chose when you deployed the model.

-> [!IMPORTANT]

-> When you access the model via the API in Azure OpenAI you will need to refer to the deployment name rather than the underlying model name in API calls. This is one of the [key differences](../how-to/switching-endpoints.md) between OpenAI and Azure OpenAI. OpenAI only requires the model name, Azure OpenAI always requires deployment name, even when using the model parameter. In our docs we often have examples where deployment names are represented as identical to model names to help indicate which model works with a particular API endpoint. Ultimately your deployment names can follow whatever naming convention is best for your use case.

-* Learn more about how to work with GPT-35-Turbo and the GPT-4 models with [our how-to guide](../how-to/chatgpt.md).

-* For more examples, check out the [Azure OpenAI Samples GitHub repository](https://aka.ms/AOAICodeSamples)

-To enable chat history, deploy or redeploy your model as a web app using [Azure OpenAI Studio](https://oai.azure.com/portal)

-* [Azure openAI on your data](../concepts/use-your-data.md)

-## Resources configuration

-> To allow access to your Azure AI Search resource from Azure OpenAI resource, you need to submit an [application form](https://aka.ms/applyacsvpnaoaioyd). The application will be reviewed in 10 business days and you will be contacted via email about the results. If you are eligible, we will provision the private endpoint in Microsoft managed virtual network, and send a private endpoint connection request to your search service, and you will need to approve the request.

-> [!NOTE]

-> The trusted service feature is only available using the command line described above, and cannot be done using the Azure portal.

-See the [ingestion API reference article](/azure/ai-services/openai/reference#start-an-ingestion-job) for details on the request and response objects used by the ingestion API.

-The Whisper models, currently in preview, can be used to transcribe and translate speech to text.

-| Max Files per resource (fine-tuning) | 30 |

-| `enhancements` | object | No | N/A | Represents the Vision enhancement features requested for the chat. It has `grounding` and `ocr` properties, each has a boolean `enabled` property. Use these to request the OCR service and/or the object detection/grounding service [This preview parameter is not available in the `2024-02-01` GA API].|

-Extensions for chat completions, for example Azure OpenAI On Your Data.

-| Parameters | Type | Required? | Default | Description |

-|--|--|--|--|--|

-| `messages` | array | Required | null | The messages to generate chat completions for, in the chat format. |

-| `dataSources` | array | Required | | The data sources to be used for the Azure OpenAI On Your Data feature. |

-| `temperature` | number | Optional | 0 | What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. We generally recommend altering this or `top_p` but not both. |

-| `top_p` | number | Optional | 1 |An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with `top_p` probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered. We generally recommend altering this or temperature but not both.|

-| `stream` | boolean | Optional | false | If set, partial message deltas are sent, like in ChatGPT. Tokens are sent as data-only server-sent events as they become available, with the stream terminated by a message `"messages": [{"delta": {"content": "[DONE]"}, "index": 2, "end_turn": true}]` |

-| `stop` | string or array | Optional | null | Up to two sequences where the API will stop generating further tokens. |

-| `max_tokens` | integer | Optional | 1000 | The maximum number of tokens allowed for the generated answer. By default, the number of tokens the model can return is `4096 - prompt_tokens`. |

-The following parameters can be used inside of the `parameters` field inside of `dataSources`.

-| Parameters | Type | Required? | Default | Description |

-|--|--|--|--|--|

-| `type` | string | Required | null | The data source to be used for the Azure OpenAI On Your Data feature. For Azure AI Search the value is `AzureCognitiveSearch`. For Azure Cosmos DB for MongoDB vCore, the value is `AzureCosmosDB`. For Elasticsearch the value is `Elasticsearch`. For Azure Machine Learning, the value is `AzureMLIndex`. For Pinecone, the value is `Pinecone`. |

-| `indexName` | string | Required | null | The search index to be used. |

-| `inScope` | boolean | Optional | true | If set, this value limits responses specific to the grounding data content. |

-| `topNDocuments` | number | Optional | 5 | Specifies the number of top-scoring documents from your data index used to generate responses. You might want to increase the value when you have short documents or want to provide more context. This is the *retrieved documents* parameter in Azure OpenAI studio. |

-| `semanticConfiguration` | string | Optional | null | The semantic search configuration. Only required when `queryType` is set to `semantic` or `vectorSemanticHybrid`. |

-| `roleInformation` | string | Optional | null | Gives the model instructions about how it should behave and the context it should reference when generating a response. Corresponds to the "System Message" in Azure OpenAI Studio. See [Using your data](./concepts/use-your-data.md#system-message) for more information. ThereΓÇÖs a 100 token limit, which counts towards the overall token limit.|

-| `filter` | string | Optional | null | The filter pattern used for [restricting access to sensitive documents](./concepts/use-your-data.md#document-level-access-control)

-| `embeddingEndpoint` | string | Optional | null | The endpoint URL for an Ada embedding model deployment, generally of the format `https://YOUR_RESOURCE_NAME.openai.azure.com/openai/deployments/YOUR_DEPLOYMENT_NAME/embeddings?api-version=2023-05-15`. Use with the `embeddingKey` parameter for [vector search](./concepts/use-your-data.md#search-types) outside of private networks and private endpoints. |

-| `embeddingKey` | string | Optional | null | The API key for an Ada embedding model deployment. Use with `embeddingEndpoint` for [vector search](./concepts/use-your-data.md#search-types) outside of private networks and private endpoints. |

-| `embeddingDeploymentName` | string | Optional | null | The Ada embedding model deployment name within the same Azure OpenAI resource. Used instead of `embeddingEndpoint` and `embeddingKey` for [vector search](./concepts/use-your-data.md#search-types). Should only be used when both the `embeddingEndpoint` and `embeddingKey` parameters are defined. When this parameter is provided, Azure OpenAI On Your Data use an internal call to evaluate the Ada embedding model, rather than calling the Azure OpenAI endpoint. This enables you to use vector search in private networks and private endpoints. Billing remains the same whether this parameter is defined or not. Available in regions where embedding models are [available](./concepts/models.md#embeddings-models) starting in API versions `2023-06-01-preview` and later.|

-| `strictness` | number | Optional | 3 | Sets the threshold to categorize documents as relevant to your queries. Raising the value means a higher threshold for relevance and filters out more less-relevant documents for responses. Setting this value too high might cause the model to fail to generate responses due to limited available documents. |

-# Azure AI SDK reference

-> The maximum JSON payload size that will be accepted is 2 megabytes. Each Speech resource can have up to 300 batch synthesis jobs that are running concurrently.

-To create a transcription, use the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation of the [Speech to text REST API](rest-speech-to-text.md#transcriptions). Construct the request body according to the following instructions:

-Make an HTTP POST request that uses the URI as shown in the following [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) example.

-The top-level `self` property in the response body is the transcription's URI. Use this URI to [get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) details such as the URI of the transcriptions and transcription report files. You also use this URI to [update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Update) or [delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete) a transcription.

-You can query the status of your transcriptions with the [Transcriptions_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) operation.

-Call [Transcriptions_Delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete)

-Here are some property options that you can use to configure a transcription when you call the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation.

-|`diarization`|Indicates that the Speech service should attempt diarization analysis on the input, which is expected to be a mono channel that contains multiple voices. The feature isn't available with stereo recordings.<br/><br/>Diarization is the process of separating speakers in audio data. The batch pipeline can recognize and separate multiple speakers on mono channel recordings.<br/><br/>Specify the minimum and maximum number of people who might be speaking. You must also set the `diarizationEnabled` property to `true`. The [transcription file](batch-transcription-get.md#transcription-result-file) contains a `speaker` entry for each transcribed phrase.<br/><br/>You need to use this property when you expect three or more speakers. For two speakers, setting `diarizationEnabled` property to `true` is enough. For an example of the property usage, see [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create).<br/><br/>The maximum number of speakers for diarization must be less than 36 and more or equal to the `minSpeakers` property. For an example, see [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create).<br/><br/>When this property is selected, source audio length can't exceed 240 minutes per file.<br/><br/>**Note**: This property is only available with Speech to text REST API version 3.1 and later. If you set this property with any previous version, such as version 3.0, it's ignored and only two speakers are identified.|

-|`timeToLive`|A duration after the transcription job is created, when the transcription results will be automatically deleted. The value is an ISO 8601 encoded duration. For example, specify `PT12H` for 12 hours. As an alternative, you can call [Transcriptions_Delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Delete) regularly after you retrieve the transcription results.|

-Whisper models by batch transcription are supported in the East US, Southeast Asia, and West Europe regions.

-You can make a [Models_ListBaseModels](https://westus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-2-preview2/operations/Models_ListBaseModels) request to get available base models for all locales.

-To get the status of the transcription job, call the [Transcriptions_Get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Get) operation of the [Speech to text REST API](rest-speech-to-text.md).

-The [Transcriptions_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) operation returns a list of result files for a transcription. A [transcription report](#transcription-report-file) file is provided for each submitted batch transcription job. In addition, one [transcription](#transcription-result-file) file (the end result) is provided for each successfully transcribed audio file.

-Batch transcription is used to transcribe a large amount of audio data in storage. Both the [Speech to text REST API](rest-speech-to-text.md#transcriptions) and [Speech CLI](spx-basics.md) support batch transcription.

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Transcription Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-> Logging data is kept for 30 days. After this period the logs are automatically deleted. This is valid for BYOS-enabled Speech resources as well. If you want to keep the logs longer, copy the correspondent files and folders from `customspeech-audiologs` Blob container directly or use REST API.

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Base Model Logs](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_ListBaseModelLogs) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-[Speech to text REST API](rest-speech-to-text.md) fully supports BYOS-enabled Speech resources. However, because the data is now stored within the BYOS-enabled Storage account, requests like [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) interact with the BYOS-associated Storage account Blob storage, instead of Speech service internal resources. It allows using the same REST API based code for both "regular" and BYOS-enabled Speech resources.

-For maximum security use the `sasValidityInSeconds` parameter with the value set to `0` in the requests, that return data file URLs, like [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) request. Here's an example request URL:

-> If `sasValidityInSeconds` parameter is omitted in [Get Dataset Files](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_ListFiles) request or similar ones, then a [User delegation SAS](../../storage/common/storage-sas-overview.md) with the validity of 30 days will be generated for each data file URL returned. This SAS is signed by the system assigned managed identity of your BYOS-enabled Speech resource. Because of it, the SAS allows access to the data, even if storage account key access is disabled. See details [here](../../storage/common/shared-key-authorization-prevent.md#understand-how-disallowing-shared-key-affects-sas-tokens).

-To create a project, use the [Projects_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Create) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-Make an HTTP POST request using the URI as shown in the following [Projects_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Create) example. Replace `YourSubscriptionKey` with your Speech resource key, replace `YourServiceRegion` with your Speech resource region, and set the request body properties as previously described.

-The top-level `self` property in the response body is the project's URI. Use this URI to [get](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Get) details about the project's evaluations, datasets, models, endpoints, and transcriptions. You also use this URI to [update](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Update) or [delete](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_Delete) a project.

-To create an endpoint and deploy a model, use the [Endpoints_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Create) operation of the [Speech to text REST API](rest-speech-to-text.md). Construct the request body according to the following instructions:

-Make an HTTP POST request using the URI as shown in the following [Endpoints_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Endpoints_Create) example. Replace `YourSubscriptionKey` with your Speech resource key, replace `YourServiceRegion` with your Speech resource region, and set the request body properties as previously described.

-> We are retiring the standard voices from September 1, 2021 through August 31, 2024. If you used a standard voice with your Speech resource that was created prior to September 1, 2021 then you can continue to do so until August 31, 2024. To use neural voices, choose voice names that include 'Neural' in their name, for example: en-US-JennyMultilingualNeural. All other Speech resources can only use prebuilt neural voices. You can choose from the supported [neural voice names](language-support.md?tabs=tts). After August 31, 2024 the standard voices won't be supported with any Speech resource.

-| `EnableMiscue` | Enables miscue calculation when the pronounced words are compared to the reference text. Enabling miscue is optional. If this value is `True`, the `ErrorType` result value can be set to `Omission` or `Insertion` based on the comparison. Values are `False` and `True`. Default: `False`. To enable miscue calculation, set the `EnableMiscue` to `True`. You can refer to the code snippet below the table. |

-| `PronScore` | Overall score of the pronunciation quality of the given speech. `PronScore` is aggregated from `AccuracyScore`, `FluencyScore`, and `CompletenessScore` with weight. |Full Text level|

-| `PronScore` | Overall score of the pronunciation quality of the given speech. This value is aggregated from `AccuracyScore`, `FluencyScore`, and `CompletenessScore` with weight. | Full Text level |

-| `Thresholds` | Suggested thresholds on both confidence scores are 0.75. That means, if the value of `UnexpectedBreak ΓÇô Confidence` is larger than 0.75, it has an unexpected break. If the value of `MissingBreak ΓÇô confidence` is larger than 0.75, it has a missing break. If you want to have variable detection sensitivity on these two breaks, you can assign different thresholds to the `UnexpectedBreak - Confidence` and `MissingBreak - Confidence` fields. |

-The following table summarizes which features that locales support. For more specifies, see the following sections.

-To identify languages with [Batch transcription REST API](batch-transcription.md), use `languageIdentification` property in the body of your [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) request.

-The table in this section summarizes the 27 locales supported for pronunciation assessment, and each language is available on all [Speech to text regions](regions.md#speech-service). Latest update extends support from English to 26 more languages and quality enhancements to existing features, including accuracy, fluency and miscue assessment. You should specify the language that you're learning or practicing improving pronunciation. The default language is set as `en-US`. If you know your target learning language, [set the locale](how-to-pronunciation-assessment.md#get-pronunciation-assessment-results) accordingly. For example, if you're learning British English, you should specify the language as `en-GB`. If you're teaching a broader language, such as Spanish, and are uncertain about which locale to select, you can run various accent models (`es-ES`, `es-MX`) to determine the one that achieves the highest score to suit your specific scenario.

-description: This document helps developers migrate code from v2 to v3 of the Speech to text REST API.speech-to-text REST API.

-# Migrate code from v2.0 to v3.0 of the REST API

-> [!IMPORTANT]

-> The Speech to text REST API v2.0 is retired as of February 29, 2024. Please migrate your applications to the Speech to text REST API v3.2. Complete the steps in this article and then see the Speech to text REST API [v3.0 to v3.1](migrate-v3-0-to-v3-1.md) and [v3.1 to v3.2](migrate-v3-1-to-v3-2.md) migration guides for additional requirements.

-## Forward compatibility

-All entities from v2.0 can also be found in the v3.0 API under the same identity. Where the schema of a result has changed (such as transcriptions), the result of a GET in the v3 version of the API uses the v3 schema. The result of a GET in the v2 version of the API uses the same v2 schema. Newly created entities on v3 aren't available in responses from v2 APIs.

-## Migration steps

-This is a summary list of items you need to be aware of when you're preparing for migration. Details are found in the individual links. Depending on your current use of the API not all steps listed here might apply. Only a few changes require nontrivial changes in the calling code. Most changes just require a change to item names.

-General changes:

-1. [Change the host name](#host-name-changes)

-1. [Rename the property ID to self in your client code](#identity-of-an-entity)

-1. [Change code to iterate over collections of entities](#working-with-collections-of-entities)

-1. [Rename the property name to displayName in your client code](#name-of-an-entity)

-1. [Adjust the retrieval of the metadata of referenced entities](#accessing-referenced-entities)

-1. If you use Batch transcription:

- * [Adjust code for creating batch transcriptions](#creating-transcriptions)

- * [Adapt code to the new transcription results schema](#format-of-v3-transcription-results)

- * [Adjust code for how results are retrieved](#getting-the-content-of-entities-and-the-results)

-1. If you use Custom model training/testing APIs:

- * [Apply modifications to custom model training](#customizing-models)

- * [Change how base and custom models are retrieved](#retrieving-base-and-custom-models)

- * [Rename the path segment accuracy tests to evaluations in your client code](#accuracy-tests)

-1. If you use endpoints APIs:

- * [Change how endpoint logs are retrieved](#retrieving-endpoint-logs)

-1. Other minor changes:

- * [Pass all custom properties as customProperties instead of properties in your POST requests](#using-custom-properties)

- * [Read the location from response header Location instead of Operation-Location](#response-headers)

-## Breaking changes

-### Host name changes

-Endpoint host names changed from `{region}.cris.ai` to `{region}.api.cognitive.microsoft.com`. Paths to the new endpoints no longer contain `api/` because it's part of the hostname. The [Speech to text REST API v3.0](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0) reference documentation lists valid regions and paths.

->[!IMPORTANT]

->Change the hostname from `{region}.cris.ai` to `{region}.api.cognitive.microsoft.com` where region is the region of your speech subscription. Also remove `api/`from any path in your client code.

-### Identity of an entity

-The property `id` is now `self`. In v2, an API user had to know how our paths on the API are being created. This was non-extensible and required unnecessary work from the user. The property `id` (uuid) is replaced by `self` (string), which is location of the entity (URL). The value is still unique between all your entities. If `id` is stored as a string in your code, a rename is enough to support the new schema. You can now use the `self` content as the URL for the `GET`, `PATCH`, and `DELETE` REST calls for your entity.

-If the entity has more functionality available through other paths, they're listed under `links`. The following example for transcription shows a separate method to `GET` the content of the transcription:

->[!IMPORTANT]

->Rename the property `id` to `self` in your client code. Change the type from `uuid` to `string` if needed.

-**v2 transcription:**

-```json

-{

- "id": "9891c965-bb32-4880-b14b-6d44efb158f3",

- "createdDateTime": "2019-01-07T11:34:12Z",

- "lastActionDateTime": "2019-01-07T11:36:07Z",

- "status": "Succeeded",

- "locale": "en-US",

- "name": "Transcription using locale en-US"

-}

-```

-**v3 transcription:**

-```json

-{

- "self": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/transcriptions/9891c965-bb32-4880-b14b-6d44efb158f3",

- "createdDateTime": "2019-01-07T11:34:12Z",

- "lastActionDateTime": "2019-01-07T11:36:07Z",

- "status": "Succeeded",

- "locale": "en-US",

- "displayName": "Transcription using locale en-US",

- "links": {

- "files": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/transcriptions/9891c965-bb32-4880-b14b-6d44efb158f3/files"

- }

-}

-```

-Depending on your code's implementation, it might not be enough to rename the property. We recommend using the returned `self` and `links` values as the target urls of your REST calls, rather than generating paths in your client. By using the returned URLs, you can be sure that future changes in paths won't break your client code.

-### Working with collections of entities

-Previously the v2 API returned all available entities in a result. To allow a more fine grained control over the expected response size in v3, all collection results are paginated. You have control over the count of returned entities and the starting offset of the page. This behavior makes it easy to predict the runtime of the response processor.

-The basic shape of the response is the same for all collections:

-```json

-{

- "values": [

- {

- }

- ],

- "@nextLink": "https://{region}.api.cognitive.microsoft.com/speechtotext/v3.0/{collection}?skip=100&top=100"

-}

-```

-The `values` property contains a subset of the available collection entities. The count and offset can be controlled using the `skip` and `top` query parameters. When `@nextLink` isn't `null`, there's more data available and the next batch of data can be retrieved by doing a GET on `$.@nextLink`.

-This change requires calling the `GET` for the collection in a loop until all elements are returned.

->[!IMPORTANT]

->When the response of a GET to `speechtotext/v3.1/{collection}` contains a value in `$.@nextLink`, continue issuing `GETs` on `$.@nextLink` until `$.@nextLink` is not set to retrieve all elements of that collection.

-### Creating transcriptions

-A detailed description on how to create batches of transcriptions can be found in [Batch transcription How-to](./batch-transcription.md).

-The v3 transcription API lets you set specific transcription options explicitly. All (optional) configuration properties can now be set in the `properties` property.

-Version v3 also supports multiple input files, so it requires a list of URLs rather than a single URL as v2 did. The v2 property name `recordingsUrl` is now `contentUrls` in v3. The functionality of analyzing sentiment in transcriptions is removed in v3. See [Text Analysis](https://azure.microsoft.com/services/cognitive-services/text-analytics/) for sentiment analysis options.

-The new property `timeToLive` under `properties` can help prune the existing completed entities. The `timeToLive` specifies a duration after which a completed entity is deleted automatically. Set it to a high value (for example `PT12H`) when the entities are continuously tracked, consumed, and deleted and therefore usually processed long before 12 hours have passed.

-**v2 transcription POST request body:**

-```json

-{

- "locale": "en-US",

- "name": "Transcription using locale en-US",

- "recordingsUrl": "https://contoso.com/mystoragelocation",

- "properties": {

- "AddDiarization": "False",

- "AddWordLevelTimestamps": "False",

- "PunctuationMode": "DictatedAndAutomatic",

- "ProfanityFilterMode": "Masked"

- }

-}

-```

-**v3 transcription POST request body:**

-```json

-{

- "locale": "en-US",

- "displayName": "Transcription using locale en-US",

- "contentUrls": [

- "https://contoso.com/mystoragelocation",

- "https://contoso.com/myotherstoragelocation"

- ],

- "properties": {

- "diarizationEnabled": false,

- "wordLevelTimestampsEnabled": false,

- "punctuationMode": "DictatedAndAutomatic",

- "profanityFilterMode": "Masked"

- }

-}

-```

->[!IMPORTANT]

->Rename the property `recordingsUrl` to `contentUrls` and pass an array of urls instead of a single url. Pass settings for `diarizationEnabled` or `wordLevelTimestampsEnabled` as `bool` instead of `string`.

-### Format of v3 transcription results

-The schema of transcription results has changed slightly to align with transcriptions created by real-time endpoints. Find an in-depth description of the new format in the [Batch transcription How-to](./batch-transcription.md). The schema of the result is published in our [GitHub sample repository](https://aka.ms/csspeech/samples) under `samples/batch/transcriptionresult_v3.schema.json`.

-Property names are now camel-cased and the values for `channel` and `speaker` now use integer types. Formats for durations now use the structure described in ISO 8601, which matches duration formatting used in other Azure APIs.

-Sample of a v3 transcription result. The differences are described in the comments.

-```json

- }

- ]

- }

- ]

- }

- ]

-}

-```

->[!IMPORTANT]

->Deserialize the transcription result into the new type as shown previously. Instead of a single file per audio channel, distinguish channels by checking the property value of `channel` for each element in `recognizedPhrases`. There is now a single result file for each input file.

-### Getting the content of entities and the results

-In v2, the links to the input or result files are inline with the rest of the entity metadata. As an improvement in v3, there's a clear separation between entity metadata (which is returned by a GET on `$.self`) and the details and credentials to access the result files. This separation helps protect customer data and allows fine control over the duration of validity of the credentials.

-In v3, `links` include a sub-property called `files` in case the entity exposes data (datasets, transcriptions, endpoints, or evaluations). A GET on `$.links.files` returns a list of files and a SAS URL

-to access the content of each file. To control the validity duration of the SAS URLs, the query parameter `sasValidityInSeconds` can be used to specify the lifetime.

-```

-The `kind` property indicates the format of content of the file. For transcriptions, the files of kind `TranscriptionReport` are the summary of the job and files of the kind `Transcription` are the result of the job itself.

->[!IMPORTANT]

->To get the results of operations, use a `GET` on `/speechtotext/v3.0/{collection}/{id}/files`, they are no longer contained in the responses of `GET` on `/speechtotext/v3.0/{collection}/{id}` or `/speechtotext/v3.0/{collection}`.

-### Customizing models

-Before v3, there was a distinction between an _acoustic model_ and a _language model_ when a model was being trained. This distinction resulted in the need to specify multiple models when creating endpoints or transcriptions. To simplify this process for a caller, we removed the differences and made everything depend on the content of the datasets that are being used for model training. With this change, the model creation now supports mixed datasets (language data and acoustic data). Endpoints and transcriptions now require only one model.

-With this change, the need for a `kind` in the `POST` operation is removed and the `datasets[]` array can now contain multiple datasets of the same or mixed kinds.

-To improve the results of a trained model, the acoustic data is automatically used internally during language training. In general, models created through the v3 API deliver more accurate results than models created with the v2 API.

->[!IMPORTANT]

->To customize both the acoustic and language model part, pass all of the required language and acoustic datasets in `datasets[]` of the POST to `/speechtotext/v3.0/models`. This will create a single model with both parts customized.

-### Retrieving base and custom models

-To simplify getting the available models, v3 has separated the collections of "base models" from the customer owned "customized models". The two routes are now

-`GET /speechtotext/v3.0/models/base` and `GET /speechtotext/v3.0/models/`.

-In v2, all models were returned together in a single response.

->[!IMPORTANT]

->To get a list of provided base models for customization, use `GET` on `/speechtotext/v3.0/models/base`. You can find your own customized models with a `GET` on `/speechtotext/v3.0/models`.

-### Name of an entity

-The `name` property is now `displayName`. This is consistent with other Azure APIs to not indicate identity properties. The value of this property must not be unique and can be changed after entity creation with a `PATCH` operation.

-**v2 transcription:**

-```json

-{

- "name": "Transcription using locale en-US"

-}

-```

-**v3 transcription:**

-```json

-{

- "displayName": "Transcription using locale en-US"

-}

-```

->[!IMPORTANT]

->Rename the property `name` to `displayName` in your client code.

-### Accessing referenced entities

-In v2, referenced entities were always inlined, for example the used models of an endpoint. The nesting of entities resulted in large responses and consumers rarely consumed the nested content. To shrink the response size and improve performance, the referenced entities are no longer inlined in the response. Instead, a reference to the other entity appears, and can directly be used for a subsequent `GET` (it's a URL as well), following the same pattern as the `self` link.

-**v2 transcription:**

-```json

-{

- "id": "9891c965-bb32-4880-b14b-6d44efb158f3",

- "models": [

-```

-**v3 transcription:**

-```json

- }

-}

-```

-If you need to consume the details of a referenced model as shown in the above example, just issue a GET on `$.model.self`.

->[!IMPORTANT]

->To retrieve the metadata of referenced entities, issue a GET on `$.{referencedEntity}.self`, for example to retrieve the model of a transcription do a `GET` on `$.model.self`.

-### Retrieving endpoint logs

-Version v2 of the service supported logging endpoint results. To retrieve the results of an endpoint with v2, you would create a "data export", which represented a snapshot of the results defined by a time range. The process of exporting batches of data was inflexible. The v3 API gives access to each individual file and allows iteration through them.

-**A successfully running v3 endpoint:**

-```json

-{

- "self": "https://eastus.api.cognitive.microsoft.com/speechtotext/v3.0/endpoints/afa0669c-a01e-4693-ae3a-93baf40f26d6",

- "links": {

- }

-}

-```

-**Response of GET `$.links.logs`:**

-```json

-}

-```

-Pagination for endpoint logs works similar to all other collections, except that no offset can be specified. Due to the large amount of available data, pagination is determined by the server.

-In v3, each endpoint log can be deleted individually by issuing a `DELETE` operation on the `self` of a file, or by using `DELETE` on `$.links.logs`. To specify an end date, the query parameter `endDate` can be added to the request.

-> [!IMPORTANT]

-> Instead of creating log exports on `/api/speechtotext/v2.0/endpoints/{id}/data` use `/v3.0/endpoints/{id}/files/logs/` to access log files individually.

-### Using custom properties

-To separate custom properties from the optional configuration properties, all explicitly named properties are now located in the `properties` property and all properties defined by the callers are now located in the `customProperties` property.

-**v2 transcription entity:**

-```json

-{

- "properties": {

- "customerDefinedKey": "value",

- "diarizationEnabled": "False",

- "wordLevelTimestampsEnabled": "False"

- }

-}

-```

-**v3 transcription entity:**

-```json

-{

- "properties": {

- "diarizationEnabled": false,

- "wordLevelTimestampsEnabled": false

- },

- "customProperties": {

- "customerDefinedKey": "value"

- }

-}

-```

-This change also lets you use correct types on all explicitly named properties under `properties` (for example boolean instead of string).

->[!IMPORTANT]

->Pass all custom properties as `customProperties` instead of `properties` in your `POST` requests.

-### Response headers

-v3 no longer returns the `Operation-Location` header in addition to the `Location` header on `POST` requests. The value of both headers in v2 was the same. Now only `Location` is returned.

-Because the new API version is now managed by Azure API management (APIM), the throttling related headers `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` aren't contained in the response headers.

->[!IMPORTANT]

->Read the location from response header `Location` instead of `Operation-Location`. In case of a 429 response code, read the `Retry-After` header value instead of `X-RateLimit-Limit`, `X-RateLimit-Remaining`, or `X-RateLimit-Reset`.

-### Accuracy tests

-Accuracy tests have been renamed to evaluations because the new name describes better what they represent. The new paths are: `https://{region}.api.cognitive.microsoft.com/speechtotext/v3.0/evaluations`.

->[!IMPORTANT]

->Rename the path segment `accuracytests` to `evaluations` in your client code.

-* [Speech to text REST API v3.0 reference](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0)

-In the [Transcriptions_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_Create) operation the following three properties are added:

-The `filter` property is added to the [Transcriptions_List](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_List), [Transcriptions_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Transcriptions_ListFiles), and [Projects_ListTranscriptions](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Projects_ListTranscriptions) operations. The `filter` expression can be used to select a subset of the available resources. You can filter by `displayName`, `description`, `createdDateTime`, `lastActionDateTime`, `status`, and `locale`. For example: `filter=createdDateTime gt 2022-02-01T11:00:00Z`

-To support model adaptation with [structured text in markdown](how-to-custom-speech-test-and-train.md#structured-text-data-for-training) data, the [Datasets_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Datasets_Create) operation now supports the **LanguageMarkdown** data kind. For more information, see [upload datasets](how-to-custom-speech-upload-data.md#upload-datasets).

-The [Models_ListBaseModels](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_ListBaseModels) and [Models_GetBaseModel](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_GetBaseModel) operations return information on the type of adaptation supported by each base model.

-The [Models_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_Create) operation has a new `customModelWeightPercent` property where you can specify the weight used when the Custom Language Model (trained from plain or structured text data) is combined with the Base Language Model. Valid values are integers between 1 and 100. The default value is currently 30.

-Added the [Models_ListFiles](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_ListFiles) operation to get the files of the model identified by the given ID.

-Added the [Models_GetFile](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_GetFile) operation to get one specific file (identified with fileId) from a model (identified with ID). This lets you retrieve a **ModelReport** file that provides information on the data processed during training.

-The name of each `operationId` in version 3.1 is prefixed with the object name. For example, the `operationId` for "Create Model" changed from [CreateModel](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-0/operations/CreateModel) in version 3.0 to [Models_Create](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_Create) in version 3.1.

-> We are retiring the standard voices from September 1, 2021 through August 31, 2024. If you used a standard voice with your Speech resource that was created prior to September 1, 2021 then you can continue to do so until August 31, 2024. All other Speech resources can only use prebuilt neural voices. You can choose from the supported [neural voice names](language-support.md?tabs=tts). After August 31, 2024 the standard voices won't be supported with any Speech resource.

-| **Speech output audio format** | opus, mp3, aac, flac | opus, mp3, pcm, truesilk | opus, mp3, pcm, truesilk |

-The following table outlines the Speech Synthesis Markup Language (SSML) elements supported by OpenAI text to speech voices in Azure AI speech. Only a subset of SSML tags are supported for OpenAI voices. See [SSML document structure and events](speech-synthesis-markup-structure.md) for more information.

-> For supported locales, see [personal voice language support](./language-support.md#personal-voice).

-The demo in Speech Studio is made available to approved customers. You can apply for access [here](https://aka.ms/customneural).

-1. Select **Request demo access**.

-1. After your access is approved, you can record your own voice and try the voice output samples in different languages. The demo includes a subset of the languages supported by personal voice.

-This article describes how to use [Power Automate](/power-automate/getting-started) and the [Azure AI services for Batch Speech to text connector](/connectors/cognitiveservicesspe/) to transcribe audio files from an Azure Storage container. The connector uses the [Batch Transcription REST API](batch-transcription.md), but you don't need to write any code to use it. If the connector doesn't meet your requirements, you can still use the [REST API](rest-speech-to-text.md#transcriptions) directly.

-2. Run the [Models_CopyTo](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1/operations/Models_CopyTo) operation to replicate the custom model to all prepared regions (Secondary).

-In this article, you learn about the benefits and capabilities of the speech translation service, which enables real-time, multi-language speech to speech and speech to text translation of audio streams.

-* Speech to text translation with recognition results.

-* Speech-to-speech translation.

-* Support for translation to multiple target languages.

-* Interim recognition and translation results.

-As your first step, try the [Speech translation quickstart](get-started-speech-translation.md). The speech translation service is available via the [Speech SDK](speech-sdk.md) and the [Speech CLI](spx-overview.md).

-spx translate --microphone --source en-US --target ru-RU;fr-FR;es-ES

-The [Swagger specification](https://eastus.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1) has options that allow you to quickly test for various paths. However, sometimes it's desirable to generate code for all paths, creating a single library of calls that you can base future solutions on. Let's take a look at the process to generate a Python library.

-1. In a browser, go to the Swagger specification for your [region](regions.md#speech-service):

- `https://<your-region>.dev.cognitive.microsoft.com/docs/services/speech-to-text-api-v3-1`

-1. On that page, select **API definition**, and select **Swagger**. Copy the URL of the page that appears.

-1. In a new browser, go to [https://editor.swagger.io](https://editor.swagger.io)

-1. Select **File**, select **Import URL**, paste the URL, and select **OK**.

-Doing some basic processing of your video data is helpful for model training efficiency, such as:

-First, you need to create a WebRTC peer connection object. WebRTC is a P2P protocol, which relies on ICE server for network relay. Azure provides [Communication Services](../../../communication-services/overview.md), which can provide network relay function. Therefore, we recommend you fetch the ICE server from the Azure Communication resource, which is mentioned in the [prerequisites section](#prerequisites). You can also choose to use your own ICE server.

-The following code snippet shows how to create the WebRTC peer connection. The ICE server URL, ICE server username, and ICE server credential can all be fetched from the network relay token you prepared in the [prerequisites section](#prerequisites) or from the configuration of your own ICE server.

-#

-recommendations: false

-# Configure Translator Docker containers

-Azure AI services provide each container with a common configuration framework. You can easily configure your Translator containers to build Translator application architecture optimized for robust cloud capabilities and edge locality.

-The **Translator** container runtime environment is configured using the `docker run` command arguments. This container has both required and optional settings. The required container-specific settings are the billing settings.

-## Configuration settings

-The container has the following configuration settings:

-|Required|Setting|Purpose|

-|--|--|--|

-|Yes|[ApiKey](#apikey-configuration-setting)|Tracks billing information.|

-|No|[ApplicationInsights](#applicationinsights-setting)|Enables adding [Azure Application Insights](/azure/application-insights) telemetric support to your container.|

-|Yes|[Billing](#billing-configuration-setting)|Specifies the endpoint URI of the service resource on Azure.|

-|Yes|[EULA](#eula-setting)| Indicates that you've accepted the license for the container.|

-|No|[Fluentd](#fluentd-settings)|Writes log and, optionally, metric data to a Fluentd server.|

-|No|HTTP Proxy|Configures an HTTP proxy for making outbound requests.|

-|No|[Logging](#logging-settings)|Provides ASP.NET Core logging support for your container. |

-|Yes|[Mounts](#mount-settings)|Reads and writes data from the host computer to the container and from the container back to the host computer.|

- > [!IMPORTANT]

-> The [**ApiKey**](#apikey-configuration-setting), [**Billing**](#billing-configuration-setting), and [**EULA**](#eula-setting) settings are used together, and you must provide valid values for all three of them; otherwise your container won't start. For more information about using these configuration settings to instantiate a container.

-## ApiKey configuration setting

-The `ApiKey` setting specifies the Azure resource key used to track billing information for the container. You must specify a value for the ApiKey and the value must be a valid key for the _Translator_ resource specified for the [`Billing`](#billing-configuration-setting) configuration setting.

-This setting can be found in the following place:

-* Azure portal: **Translator** resource management, under **Keys**

-## ApplicationInsights setting

-## Billing configuration setting

-The `Billing` setting specifies the endpoint URI of the _Translator_ resource on Azure used to meter billing information for the container. You must specify a value for this configuration setting, and the value must be a valid endpoint URI for a _Translator_ resource on Azure. The container reports usage about every 10 to 15 minutes.

-This setting can be found in the following place:

-* Azure portal: **Translator** Overview page labeled `Endpoint`

-| Required | Name | Data type | Description |

-| -- | - | | -- |

-| Yes | `Billing` | String | Billing endpoint URI. For more information on obtaining the billing URI, see [gathering required parameters](translator-how-to-install-container.md#required-elements). For more information and a complete list of regional endpoints, see [Custom subdomain names for Azure AI services](../../cognitive-services-custom-subdomains.md). |

-## EULA setting

-## Fluentd settings

-## HTTP/HTTPS proxy credentials settings

-If you need to configure an HTTP proxy for making outbound requests, use these two arguments:

-| Name | Data type | Description |

-|--|--|--|

-|HTTPS_PROXY|string|The proxy to use, for example, `https://proxy:8888`<br>`<proxy-url>`|

-|HTTP_PROXY_CREDS|string|Any credentials needed to authenticate against the proxy, for example, `username:password`. This value **must be in lower-case**. |

-|`<proxy-user>`|string|The user for the proxy.|

-|`<proxy-password>`|string|The password associated with `<proxy-user>` for the proxy.|

-||||

-```bash

-docker run --rm -it -p 5000:5000 \

-<registry-location>/<image-name> \

-Eula=accept \

-Billing=<endpoint> \

-ApiKey=<api-key> \

-HTTPS_PROXY=<proxy-url> \

-HTTP_PROXY_CREDS=<proxy-user>:<proxy-password> \

-```

-## Logging settings

-Translator containers support the following logging providers:

-|Provider|Purpose|

-|--|--|

-|[Console](/aspnet/core/fundamentals/logging/#console-provider)|The ASP.NET Core `Console` logging provider. All of the ASP.NET Core configuration settings and default values for this logging provider are supported.|

-|[Debug](/aspnet/core/fundamentals/logging/#debug-provider)|The ASP.NET Core `Debug` logging provider. All of the ASP.NET Core configuration settings and default values for this logging provider are supported.|

-|[Disk](#disk-logging)|The JSON logging provider. This logging provider writes log data to the output mount.|

-* The `Logging` settings manage ASP.NET Core logging support for your container. You can use the same configuration settings and values for your container that you use for an ASP.NET Core application.

-* The `Logging.LogLevel` specifies the minimum level to log. The severity of the `LogLevel` ranges from 0 to 6. When a `LogLevel` is specified, logging is enabled for messages at the specified level and higher: Trace = 0, Debug = 1, Information = 2, Warning = 3, Error = 4, Critical = 5, None = 6.

-* Currently, Translator containers have the ability to restrict logs at the **Warning** LogLevel or higher.

-The general command syntax for logging is as follows:

-```bash

- -Logging:LogLevel:{Provider}={FilterSpecs}

-```

-The following command starts the Docker container with the `LogLevel` set to **Warning** and logging provider set to **Console**. This command prints anomalous or unexpected events during the application flow to the console:

-```bash

-docker run --rm -it -p 5000:5000

-mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest

-```

-### Disk logging

-The `Disk` logging provider supports the following configuration settings:

-| Name | Data type | Description |

-||--|-|

-| `Format` | String | The output format for log files.<br/> **Note:** This value must be set to `json` to enable the logging provider. If this value is specified without also specifying an output mount while instantiating a container, an error occurs. |

-| `MaxFileSize` | Integer | The maximum size, in megabytes (MB), of a log file. When the size of the current log file meets or exceeds this value, the logging provider starts a new log file. If -1 is specified, the size of the log file is limited only by the maximum file size, if any, for the output mount. The default value is 1. |

-#### Disk provider example

-```bash

-docker run --rm -it -p 5000:5000 \

-Eula=accept \

-Billing=<endpoint> \

-ApiKey=<api-key> \

-Logging:Disk:Format=json \

-Mounts:Output=/output

-```

-For more information about configuring ASP.NET Core logging support, see [Settings file configuration](/aspnet/core/fundamentals/logging/).

-## Mount settings

-Use bind mounts to read and write data to and from the container. You can specify an input mount or output mount by specifying the `--mount` option in the [docker run](https://docs.docker.com/engine/reference/commandline/run/) command.

-# Container: Translate

-Translate text.

-## Request URL

-Send a `POST` request to:

-```HTTP

-http://localhost:{port}/translate?api-version=3.0

-```

-Example: http://<span></span>localhost:5000/translate?api-version=3.0

-## Request parameters

-Request parameters passed on the query string are:

-### Required parameters

-| Query parameter | Description |

-| | |

-| api-version | _Required parameter_. <br>Version of the API requested by the client. Value must be `3.0`. |

-| from | _Required parameter_. <br>Specifies the language of the input text. Find which languages are available to translate from by looking up [supported languages](../reference/v3-0-languages.md) using the `translation` scope.|

-| to | _Required parameter_. <br>Specifies the language of the output text. The target language must be one of the [supported languages](../reference/v3-0-languages.md) included in the `translation` scope. For example, use `to=de` to translate to German. <br>It's possible to translate to multiple languages simultaneously by repeating the parameter in the query string. For example, use `to=de&to=it` to translate to German and Italian. |

-### Optional parameters

-| Query parameter | Description |

-| | |

-| textType | _Optional parameter_. <br>Defines whether the text being translated is plain text or HTML text. Any HTML needs to be a well-formed, complete element. Possible values are: `plain` (default) or `html`. |

-| includeSentenceLength | _Optional parameter_. <br>Specifies whether to include sentence boundaries for the input text and the translated text. Possible values are: `true` or `false` (default). |

-Request headers include:

-| Headers | Description |

-| | |

-| Authentication header(s) | _Required request header_. <br>See [available options for authentication](../reference/v3-0-reference.md#authentication). |

-| Content-Type | _Required request header_. <br>Specifies the content type of the payload. <br>Accepted value is `application/json; charset=UTF-8`. |

-| Content-Length | _Required request header_. <br>The length of the request body. |

-| X-ClientTraceId | _Optional_. <br>A client-generated GUID to uniquely identify the request. You can omit this header if you include the trace ID in the query string using a query parameter named `ClientTraceId`. |

-## Request body

-The body of the request is a JSON array. Each array element is a JSON object with a string property named `Text`, which represents the string to translate.

-```json

-[

- {"Text":"I would really like to drive your car around the block a few times."}

-]

-```

-The following limitations apply:

-* The array can have at most 100 elements.

-* The entire text included in the request can't exceed 10,000 characters including spaces.

-## Response body

-A successful response is a JSON array with one result for each string in the input array. A result object includes the following properties:

-* `translations`: An array of translation results. The size of the array matches the number of target languages specified through the `to` query parameter. Each element in the array includes:

-* `to`: A string representing the language code of the target language.

-* `text`: A string giving the translated text.

-* `sentLen`: An object returning sentence boundaries in the input and output texts.

-* `srcSentLen`: An integer array representing the lengths of the sentences in the input text. The length of the array is the number of sentences, and the values are the length of each sentence.

-* `transSentLen`: An integer array representing the lengths of the sentences in the translated text. The length of the array is the number of sentences, and the values are the length of each sentence.

- Sentence boundaries are only included when the request parameter `includeSentenceLength` is `true`.

- * `sourceText`: An object with a single string property named `text`, which gives the input text in the default script of the source language. `sourceText` property is present only when the input is expressed in a script that's not the usual script for the language. For example, if the input were Arabic written in Latin script, then `sourceText.text` would be the same Arabic text converted into Arab script.

-Examples of JSON responses are provided in the [examples](#examples) section.

-## Response headers

-| Headers | Description |

-| | |

-| X-RequestId | Value generated by the service to identify the request. It's used for troubleshooting purposes. |

-| X-MT-System | Specifies the system type that was used for translation for each 'to' language requested for translation. The value is a comma-separated list of strings. Each string indicates a type: </br></br>&FilledVerySmallSquare; Custom - Request includes a custom system and at least one custom system was used during translation.</br>&FilledVerySmallSquare; Team - All other requests |

-## Response status codes

-If an error occurs, the request will also return a JSON error response. The error code is a 6-digit number combining the 3-digit HTTP status code followed by a 3-digit number to further categorize the error. Common error codes can be found on the [v3 Translator reference page](../reference/v3-0-reference.md#errors).

-## Examples

-### Translate a single input

-This example shows how to translate a single sentence from English to Simplified Chinese.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}]"

-```

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"}

- ]

- }

-]

-```

-The `translations` array includes one element, which provides the translation of the single piece of text in the input.

-### Translate multiple pieces of text

-Translating multiple strings at once is simply a matter of specifying an array of strings in the request body.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}, {'Text':'I am fine, thank you.'}]"

-```

-The response contains the translation of all pieces of text in the exact same order as in the request.

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"}

- ]

- },

- {

- "translations":[

- {"text":"我很好，谢谢你。","to":"zh-Hans"}

- ]

- }

-]

-```

-### Translate to multiple languages

-This example shows how to translate the same input to several languages in one request.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans&to=de" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'Hello, what is your name?'}]"

-```

-The response body is:

-```

-[

- {

- "translations":[

- {"text":"你好, 你叫什么名字？","to":"zh-Hans"},

- {"text":"Hallo, was ist dein Name?","to":"de"}

- ]

- }

-]

-```

-### Translate content with markup and decide what's translated

-It's common to translate content that includes markup such as content from an HTML page or content from an XML document. Include query parameter `textType=html` when translating content with tags. In addition, it's sometimes useful to exclude specific content from translation. You can use the attribute `class=notranslate` to specify content that should remain in its original language. In the following example, the content inside the first `div` element won't be translated, while the content in the second `div` element will be translated.

-```

-<div class="notranslate">This will not be translated.</div>

-<div>This will be translated. </div>

-```

-Here's a sample request to illustrate.

-```curl

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=zh-Hans&textType=html" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'<div class=\"notranslate\">This will not be translated.</div><div>This will be translated.</div>'}]"

-```

-The response is:

-```

-[

- {

- "translations":[

- {"text":"<div class=\"notranslate\">This will not be translated.</div><div>这将被翻译。</div>","to":"zh-Hans"}

- ]

- }

-]

-```

-### Translate with dynamic dictionary

-If you already know the translation you want to apply to a word or a phrase, you can supply it as markup within the request. The dynamic dictionary is only safe for proper nouns such as personal names and product names.

-The markup to supply uses the following syntax.

-```

-<mstrans:dictionary translation="translation of phrase">phrase</mstrans:dictionary>

-```

-For example, consider the English sentence "The word wordomatic is a dictionary entry." To preserve the word _wordomatic_ in the translation, send the request:

-```

-curl -X POST "http://localhost:{port}/translate?api-version=3.0&from=en&to=de" -H "Ocp-Apim-Subscription-Key: <client-secret>" -H "Content-Type: application/json; charset=UTF-8" -d "[{'Text':'The word <mstrans:dictionary translation=\"wordomatic\">word or phrase</mstrans:dictionary> is a dictionary entry.'}]"

-```

-The result is:

-```

-[

- {

- "translations":[

- {"text":"Das Wort \"wordomatic\" ist ein W├╢rterbucheintrag.","to":"de"}

- ]

- }

-]

-```

-This feature works the same way with `textType=text` or with `textType=html`. The feature should be used sparingly. The appropriate and far better way of customizing translation is by using Custom Translator. Custom Translator makes full use of context and statistical probabilities. If you've created training data that shows your work or phrase in context, you'll get much better results. [Learn more about Custom Translator](../custom-translator/concepts/customization.md).

-## Request limits

-Each translate request is limited to 10,000 characters, across all the target languages you're translating to. For example, sending a translate request of 3,000 characters to translate to three different languages results in a request size of 3000x3 = 9,000 characters, which satisfy the request limit. You're charged per character, not by the number of requests. It's recommended to send shorter requests.

-The following table lists array element and character limits for the Translator **translation** operation.

-| Operation | Maximum size of array element | Maximum number of array elements | Maximum request size (characters) |

-|:-|:-|:-|:-|

-| translate | 10,000 | 100 | 10,000 |

-Before attempting to run a Docker container in an offline environment, make sure you're familiar with the following requirements to successfully download and use the container:

-* Host computer requirements and recommendations.

-* The Docker `pull` command to download the container.

-* How to validate that a container is running.

-* How to send queries to the container's endpoint, once it's running.

-## Request access to use containers in disconnected environments

-Complete and submit the [request form](https://aka.ms/csdisconnectedcontainers) to request access to the containers disconnected from the Internet.

-Access is limited to customers that meet the following requirements:

-* Your organization should be identified as strategic customer or partner with Microsoft.

-* Disconnected containers are expected to run fully offline, hence your use cases must meet at least one of these or similar requirements:

- * Environment or device(s) with zero connectivity to internet.

- * Remote location that occasionally has internet access.

- * Organization under strict regulation of not sending any kind of data back to cloud.

-* Application completed as instructed. Make certain to pay close attention to guidance provided throughout the application to ensure you provide all the necessary information required for approval.

-## Create a new resource and purchase a commitment plan

-1. Create a [Translator resource](https://portal.azure.com/#create/Microsoft.CognitiveServicesTextTranslation) in the Azure portal.

-1. Enter the applicable information to create your resource. Be sure to select **Commitment tier disconnected containers** as your pricing tier.

- > [!NOTE]

- >

- > * You will only see the option to purchase a commitment tier if you have been approved by Microsoft.

- :::image type="content" source="../media/create-resource-offline-container.png" alt-text="A screenshot showing resource creation on the Azure portal.":::

-1. Select **Review + Create** at the bottom of the page. Review the information, and select **Create**.

-## Gather required parameters

-There are three required parameters for all Azure AI services' containers:

-* The end-user license agreement (EULA) must be present with a value of *accept*.

-* The endpoint URL for your resource from the Azure portal.

-* The API key for your resource from the Azure portal.

-Both the endpoint URL and API key are needed when you first run the container to configure it for disconnected usage. You can find the key and endpoint on the **Key and endpoint** page for your resource in the Azure portal:

- :::image type="content" source="../media/quickstarts/keys-and-endpoint-portal.png" alt-text="Screenshot of Azure portal keys and endpoint page.":::

-> [!IMPORTANT]

-> You will only use your key and endpoint to configure the container to run in a disconnected environment. After you configure the container, you won't need the key and endpoint values to send API requests. Store them securely, for example, using Azure Key Vault. Only one key is necessary for this process.

-## Download a Docker container with `docker pull`

-Download the Docker container that has been approved to run in a disconnected environment. For example:

-|Docker pull command | Value |Format|

-|-|-||

-|&bullet; **`docker pull [image]`**</br>&bullet; **`docker pull [image]:latest`**|The latest container image.|&bullet; mcr.microsoft.com/azure-cognitive-services/translator/text-translation</br> </br>&bullet; mcr.microsoft.com/azure-cognitive-services/translator/text-translation: latest |

-|||

-|&bullet; **`docker pull [image]:[version]`** | A specific container image |mcr.microsoft.com/azure-cognitive-services/translator/text-translation:1.0.019410001-amd64 |

- **Example Docker pull command**

-```docker

-docker pull mcr.microsoft.com/azure-cognitive-services/translator/text-translation:latest

-```

-## Configure the container to run in a disconnected environment

-Now that you've downloaded your container, you need to execute the `docker run` command with the following parameters:

-* **`DownloadLicense=True`**. This parameter downloads a license file that enables your Docker container to run when it isn't connected to the internet. It also contains an expiration date, after which the license file is invalid to run the container. You can only use the license file in corresponding approved container.

-* **`Languages={language list}`**. You must include this parameter to download model files for the [languages](../language-support.md) you want to translate.

-> [!IMPORTANT]

-> The `docker run` command will generate a template that you can use to run the container. The template contains parameters you'll need for the downloaded models and configuration file. Make sure you save this template.

-The following example shows the formatting for the `docker run` command with placeholder values. Replace these placeholder values with your own values.

-| Placeholder | Value | Format|

-|-|-||

-| `[image]` | The container image you want to use. | `mcr.microsoft.com/azure-cognitive-services/translator/text-translation` |

-| `{LICENSE_MOUNT}` | The path where the license is downloaded, and mounted. | `/host/license:/path/to/license/directory` |

- | `{MODEL_MOUNT_PATH}`| The path where the machine translation models are downloaded, and mounted. Your directory structure must be formatted as **/usr/local/models** | `/host/translator/models:/usr/local/models`|

-| `{ENDPOINT_URI}` | The endpoint for authenticating your service request. You can find it on your resource's **Key and endpoint** page, in the Azure portal. | `https://<your-custom-subdomain>.cognitiveservices.azure.com` |

-| `{API_KEY}` | The key for your Text Translation resource. You can find it on your resource's **Key and endpoint** page, in the Azure portal. |`{string}`|

-| `{LANGUAGES_LIST}` | List of language codes separated by commas. It's mandatory to have English (en) language as part of the list.| `en`, `fr`, `it`, `zu`, `uk` |

-| `{CONTAINER_LICENSE_DIRECTORY}` | Location of the license folder on the container's local filesystem. | `/path/to/license/directory` |

- **Example `docker run` command**

-```docker

-docker run --rm -it -p 5000:5000 \

-[image]

-```

-### Translator translation models and container configuration

-After you've [configured the container](#configure-the-container-to-run-in-a-disconnected-environment), the values for the downloaded translation models and container configuration will be generated and displayed in the container output:

-```bash

- -e MODELS= usr/local/models/model1/, usr/local/models/model2/

- -e TRANSLATORSYSTEMCONFIG=/usr/local/models/Config/5a72fa7c-394b-45db-8c06-ecdfc98c0832

-```
