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 aSpeechConfig. 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.

1 The region has dedicated hardware for custom speech training. If you plan to train a custom model with audio data, you must use one of the regions with dedicated hardware. Then you can copy the trained model to another region.
2 The region is available for custom neural voice training. You can copy a trained neural voice model to other regions for deployment.
3 The region doesn't support Batch Synthesis API.
4 The region supports custom keyword advanced models.
5 The region supports keyword verification.
6 The region doesn't support Speaker Recognition.
7 The region supports the high performance endpoint type for custom neural voice.
8 The region doesn't support Custom Neural Voice.
9 The region supports personal voice.
10 The region supports text to speech avatar.
11 The region supports video translation.
12 The region supports fast transcription.
