The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I was able to reproduce the issue using Ubuntu 20.04 using FF build 117.0 (although tab is muted sound is heard while drawing).
Marking issue as new.

Working for me on Windows. Once i mute the tab I no longer hear anything.

Thanks for the simple testcase in the attachment. That produces sound even when muted with Nightly on Linux.

Given the linux-but-not-windows reproduction, I suspect something is not behaving as desired in SpeechDispatcherService code.
A comment acknowledges ineffectiveness mid-utterance, but this is reproducing even when muting before speak() is called.

This code is about how we mute web speech before. If now it doesn't work, then probably means something broken around those functions.
