Speech Synthesizer behavior change in V4

See original GitHub issue

Version

4.6 vis CDN

Describe the bug

In V3, we had an option to stop the speech from code and after that, the speech synthesizes won’t work until the user again uses speech recognizer.

In V4, this behavior has changed. The bot speaks out every message even after stoping it from code.

To Reproduce

Steps to reproduce the behavior:

Go to any voice-enabled samples.
Click on mic
Speak something to the bot and wait for the bot to speak back.
Execute the code segment speechServicesPonyfill.speechSynthesis.queue.stop(); speechServicesPonyfill.speechSynthesis.cancel(); The speech will stop now.
Now type something to the bot. The reply will be again spoken by the bot.

Expected behavior

The bot should not speak once this code segment is executed. This was the behavior in V3.

Additional context

This is an upgrade issue and the context is that if we minimize the bot and we trigger any message from the user to the bot via piggybacking, the reply will be spoken by the bot even when it is minimized.

@alokraj68 are you trying to stop all speech synthesis?

If yes, this sample will help, https://github.com/microsoft/BotFramework-WebChat/tree/master/samples/03.speech/d.cognitive-speech-services-speech-recognition-only.

This sample build a partial adapter that enable speech recognition but disable speech synthesis, which will aid in your case if you are stopping all speech synthesis.
