See who is speaking or presenting
An icon will indicate if a participant is speaking or sending audible background noise.
In the screenshot below, Sandra Ty is currently audible. Sally Wood has been audible within the last 30 seconds, so the icon is still displayed, but has turned gray.
If you filter by Speaking participants, you will see all participants who are currently audible, as well as participants who have been audible within the last 30 seconds.
Another icon will indicate if a participant is presenting.
