Enables or disables Active Speaker mode for the call.
Our Daily Prebuilt Active Speaker feature displays the participant who is currently speaking prominently, while others are displayed smaller. Active speaker mode only applies to the local participant, so changing the mode only changes the view locally.
If you are not currently in a call (you have not
join()ed one), this method will have no effect.
To specify the initial mode when you first
join() a call, set the
activeSpeakerMode call property.
