I am using following article to enable speech, which is working fine in Chrome (even with bing speech).

However same is not working in Firefox, though it has been mentioned that it should work in Firefox. I also posted same question here, but havent got a reply, any suggestion? https://github.com/Microsoft/BotFramework-WebChat/issues/1141

Answer 2

I do a test to enable speech recognition and synthesis in the Web Chat control via Bing Speech service, which can work in both Chrome and Firefox.

To troubleshoot the issue, you can try:

1) Upgrade your Firefox to the latest version, I'm using Version 62.0

2) Make sure you allow your site to use your microphone
