Abstract
Systems and methods for active speaker detection for videoconferencing are provided. For example, an audio recording system can record a set of raw audio signals. The set of raw audio signals include audio signals recorded by a set of microphones at different distances from an audio source with different orientations. An audio dataset generation system can access a virtual meeting room setup which specifies microphones used in a virtual meeting room, locations of speakers and the microphones, and orientations of the speakers. The audio dataset generation system generates a synthetic audio signal for each of the speakers specified in the virtual meeting room setup by combining audio signals selected from the set of raw audio signals according to the virtual meeting room setup.
