Speech Service supported regions

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

Make sure that you use the endpoint that matches the region for your subscription.

Speech SDK

In the Speech SDK, regions are specified as a string (for example, as a parameter to SpeechConfig.FromSubscription in the Speech SDK for C#).

Speech-to-text, text-to-speech, and translation

The Speech SDK is available in these regions for speech recognition, text-to-speech, and translation:
