Supported regions for Azure Speech

Azure Speech allows your application to convert audio to text, perform speech translation, and convert text to speech. Azure Speech is available in multiple regions with unique endpoints for the Speech SDK and REST APIs.

Use region identifiers

When configuring Azure Speech in your application:

Provide the region identifier (such as westus) when you create a SpeechConfig instance with the Speech SDK. Make sure the region matches your Azure Speech resource.
Use the region as part of the endpoint URI when making requests to the Speech REST APIs.
Keys are region-scoped — using a key with a different region returns authentication errors.

Note

Azure Speech doesn't store or process your data outside the region of your Azure Speech resource. The data is stored or processed only in the region where the resource is created. For example, if you create a Foundry resource for speech in the westus region, the data is only in the westus region.

Regions

The regions in the following tables support most of the core features of Azure Speech, such as speech to text, text to speech, and translation. Some features, such as fast transcription and batch synthesis, require specific regions. For the features that require specific regions, the tables indicate the regions that support them.

¹ Supports the processing of custom speech models.

² The region uses dedicated hardware for custom speech training. If you plan to train a custom model, you must use one of the regions that have dedicated hardware. Then you can copy the trained model to another region.
