Language documentation and resources

Frequently asked questions about AI Language

  • Capabilities previously available in these services are upgraded with the latest AI and offered as capabilities in Language. Language offers a unified studio experience and unified SDKs in popular programming languages to build natural-language AI into your applications. Choose from 12 ready-to-use capabilities and easily customize with your labeled data, or simply annotate data using the data-labeling canvas.

  • Language represents a commitment to provide you with the latest natural language capabilities. It consolidates familiar capabilities previously available in Text Analytics, QnA Maker, and LUIS into a unified service. Use these capabilities in a single convenient SDK by creating a AI Language resource.

  • To get started, you’ll need to create a AI Language resource. Visit the Azure portal, select “create a resource,” and search for AI Language. Once you have a resource, use the capabilities via the API or SDK (for Python or C#). Download the SDK from the Azure portal, PyPi, or NuGet.

  • Text Analytics (including question answering) customers benefit from the unified AI Language without interruption, while classic QnA Maker and LUIS customers need to migrate to use the unified AI Language. The migration is a simple process. See the documentation for detailed migration steps.

  • See each feature's supported languages in the AI Language documentation for more information.

  • Yes, use the analyze operation to combine more than one feature in the same asynchronous call. The analyze operation is currently only available in the Standard pricing tier and follows the same pricing criteria.

  • LUIS will continue to be supported and maintained as a GA service and customers are not required to migrate to the AI Language as both products will be maintained.
