In one embodiment, a system detects a lecturer within a videoconference. The system includes two or more participant systems and a media switch coupled to each of the participant systems. The media switch includes a switch processor to receive and process audio and video information from the participant systems. The switch processor analyzes loudness metric values of active speakers and designates a particular speaker as a lecturer. In addition, the switch processor provides audio and video information of the remaining conference participants to the lecturer participant system to rotate through conference participants with each participant being displayed to the lecturer for a predetermined interval (e.g., in a round robin fashion), thereby enabling the lecturer to view the entire audience.
