What is Active Speaker Mode?
Active Speaker is a dynamic video layout that automatically detects who is talking (using VAD) and displays their video feed in the largest, central part of the screen. Other participants are usually shown in a smaller filmstrip or thumbnail row.
How it Works
- Audio Level Detection: The system monitors the audio volume of all participants.
- Switching Logic: To prevent rapid, dizzying switching (e.g., if someone coughs), algorithms usually require a person to speak for a certain duration (e.g., 500ms) and volume threshold before switching the main view.
- Last Active: When no one is speaking, the view typically remains on the last person who spoke.
