Speech Service supported regions
![Doug Erickson [MSFT]](https://github.com/erickson-doug.png?size=32)
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:

This is a subset of the publishing regions supported by the Language Understanding service (LUIS).
REST APIs
The Speech service also exposes REST endpoints for speech-to-text and text-to-speech requests.
Speech-to-text
For speech-to-text reference documentation, see Speech-to-text REST API.

Note
The language parameter must be appended to the URL to avoid receiving an 4xx HTTP error. For example, the language set to US English using the West US endpoint is: https://westus.stt.speech.microsoft.com/speech/recognition/conversation/speech/recognition/conversation/cognitiveservices/v1?language=en-US.
Text-to-speech
For text-to-speech reference documentation, see Text-to-speech REST API.
