Active speaker mode is a feature of the prebuilt UI that highlights the participant who is talking. It helps preserve bandwidth to improve video call quality.
- To turn it on or off from the prebuilt UI, click on More, in the lower right of your in-call menu. Then select Active Speaker mode.
- To turn it on or off programmatically, read about
setActiveSpeakerMode()
in Daily's reference docs.
Note that active speaker mode only exists for calls that use the built-in UI. If you’ve provided custom CSS (through a factory method, join()
, or loadCss()
) or are using a Call Object (created with DailyIframe.createCallObject()
), this method will have no effect. However, you can listen to active-speaker-change
events to build your own active speaker mode in a custom UI.
