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 stores and processes speech data in the region where you create your resource. Voice Live is an exception: speech recognition, HD voice synthesis, and LLM inference have separate processing scopes. Processing can occur outside your resource region. See Voice Live region support.

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.

Voice Live speech features and large language models (LLMs) have separate regional availability and data processing (inference) scopes. Check both tables when you choose a resource region.

Speech feature availability and processing scope

Azure Speech standard high-definition (HD) voices are available in all Voice Live resource regions listed in the following table. Voice Live routes synthesis to an HD-capable region when HD voices aren't available locally. The Text to speech tab describes standalone Speech availability, not HD voice availability through Voice Live.

mai-transcribe-2 is also available in all listed regions. mai-transcribe-2-streaming is available only in the indicated regions. The mai-transcribe alias uses the same availability and processing scope as mai-transcribe-2.

Each cell shows the feature's processing scope: Global, Data zone, or Regional. A dash (-) means the feature isn't available through Voice Live in that resource region. These scopes apply to speech input or output, independently of the LLM scope.

LLM availability and processing scope

The following table lists predeployed LLM availability by Voice Live resource region. Each model cell shows the LLM's data processing (inference) scope: Global, Data zone, or Regional. A dash (-) means the model isn't available in that resource region. This table doesn't describe speech recognition or HD voice synthesis availability.

Note

The gpt-realtime-datazone, gpt-realtime-1.5-datazone, and gpt-realtime-2.1-datazone models use data zone processing. Prompts and responses are processed only within the data zone associated with your resource's region.

Note

Models gpt-5.5, gpt-5.4-mini and gpt-5.4-nano are supported and tested with Voice Live but aren't pre-deployed. To use them, deploy them in your Foundry resource and connect via Bring Your Own Model (BYOM).
