Speech service supported regions
The Speech service allows your application to convert audio to text, perform speech translation, and convert text to speech. The service is available in multiple regions with unique endpoints for the Speech SDK and REST APIs. You can perform custom configurations to your speech experience, for all regions, at the Speech Studio.
Keep in mind the following points:
- If your application uses a Speech SDK, you provide the region identifier, such as
westus, when you create a speech configuration. Make sure the region matches the region of your subscription. - If your application uses one of the Speech service REST APIs, the region is part of the endpoint URI you use when making requests.
- Keys created for a region are valid only in that region. If you attempt to use them with other regions, you get authentication errors.
Note
Speech service doesn't store or process customer data outside the region the customer deploys the service instance in.
Speech SDK
In the Speech SDK, you specify the region as a parameter (for example, in the Speech SDK for C#, you specify the region as a parameter to SpeechConfig.FromSubscription).
Speech-to-text, pronunciation assessment, text-to-speech, and translation
The Speech service is available in these regions for speech-to-text, pronunciation assessment, text-to-speech, and translation:

1 The region has dedicated hardware for Custom Speech training. In regions with dedicated hardware for Custom Speech training, the Speech service will use up to 20 hours of your audio training data, and can process about 10 hours of data per day. In other regions, the Speech service uses up to 8 hours of your audio data, and can process about 1 hour of data per day.
If you plan to train a custom model with audio data, use one of the regions with dedicated hardware for faster training. Then you can use the Speech-to-text REST API v3.0 to copy the trained model to another region.
Tip
For pronunciation assessment, en-US and en-GB are available in all regions listed above, zh-CN is available in East Asia and Southeast Asia regions, de-DE, es-ES, and fr-FR are available in West Europe region, and en-AU is available in Australia East region.
