Azure speech to text does not hear sound from stereo mix.

tayfun kaya 5

google translate microphone detects voice very well, but azure speech to text microphone does not detect any sound.

https://speech.microsoft.com/portal/speechtotexttool

I recorded audio from the above site and when I listened to the audio I recorded, I only heard a sizzling sound.

tayfun kaya Are you using the mic button to record audio from the tool?

The recordings from my session seem fine, are you using any external audio to play sound instead of a microphone?

Also, does the browser have the requested permission to record audio when you hit the mic button?

Yes, seems like something is wrong in your case. Do you see same behavior with a different browser or machine?

I would request to collect the trace logs of this session and report the same through an azure support case with the Azure Speech service team. You can collect the same as HAR file and attach it with your support case.
