[Azure Gov] Cognitive Speech API always points to commercial

[p-nagpal]

This comes from a customer issue: microsoft/BotFramework-WebChat#2969

Webchat consumes the cognitive-services-speech-sdk-js and we found that the endpoints for STT API always point to commercial cloud. From customer issue report:

Cognitive Speech API in webchat always points to the commercial endpoint. wss://virginia.stt.speech.microsoft.com instead of wss://virginia.stt.speech.azure.us as stated in this link. This is regardless of using "virginia" or "usgovvirginia" as the region parameter when constructing webSpeechPonyfillFactory.

We noticed that SpeechConnectionFactory uses .stt.speech.microsoft.com regardless of the region and perhaps this is the cause of the issue.

Could you advise us on how to use Speech API in Azure Gov clouds?

From the link:
SR in SpeechSDK: config.fromHost("wss://virginia.stt.speech.azure.us", "");

For the Soverign Clouds you need to use the fromHost method to get the right endpoint.

We're investigating more streamlined solutions in the long run, but for now...

Thanks @rhurey for the tips.

This is done on Web Chat side, in this PR, microsoft/BotFramework-WebChat#3040.

The work is only for traditional STT/TTS but not Direct Line Speech.
