Speech: Microphone not respecting input hint

[eljodon]

The microphone keeps activating and listening after a message is received, ignoring the message input hint value. This behavior is happening in the latest Chrome and Edge browsers at least.

I am using the the latest full bundle:

Got it, will work on it. 😉

Need to figure out the corner case:

• The bot send 2 successive activities after the user talk to a bot using speech
  • First incoming activity has inputHint set to expectingInput
  • Second incoming activity has inputHint set to ignoringInput
  • What is the expected behavior? Either one of the following
    • After speaking first and second activity, we should start recording, or,
    • After speaking first and second activity, we should not start recording

@lauren-mills provided very helpful input that I will copy-paste below: (emphasis mine)

The approach that seems to work best is that each message should be IgnoringInput except for the final message on a turn, which should be ExpectingInput for prompts or AcceptingInput for other messages. This approach prevents the bot from ever listening to itself and getting stuck in a feedback loop.
