From: Room-localized speech activity detection in multi-microphone smart homes
An example of room-independent vs. room-localized SAD in multi-room domestic environments equipped with multiple microphones. Here, three speakers are active in three rooms. Left: floor plan of the smart home used in the DIRHA project [10] (see also Section 7.1 and Fig. 6), with dots indicating microphone locations on the apartment walls and ceiling. Right: 1-min-long waveforms, captured by the red-colored microphones (one per room with an active speaker), shown together with the corresponding ground truth of room-localized SAD. The room-independent speech/non-speech segmentation is also depicted at the top
