Active Speaker` is a feature that highlights the person currently talking in video calls, improving conversation flow and preserving bandwidth for better quality. The two components of this feature are `Indicator UI` and `Active Speaker Layout`, with the latter displaying the speaker's video feed prominently in the center of the screen while minimizing other participants' feeds to the lower right corner. This layout helps save data and improve call quality, but its setting is not remembered when the call ends. The feature was initially automatically triggered by poor connections but was changed based on user feedback, who found it distracting during team calls.
