Source/WebKit:

We currently only allow one page to capture media at a time and we did this by muting (stop capture in) other
pages. To make speech recognition work with this behavior, two changes are made:

  1. when page is muted, mute audio capture source used for speech recognition on the page. This will

ultimately fail recognition.

  1. when speech recognition is about to start, make sure other pages are muted for capture.
