Abstract
The sound collection system includes: a first beamformer that outputs a first signal obtained by emphasizing sound coming from a direction within a first range, among sound arriving at a plurality of microphones, more than sound coming from other directions; a second beamformer that outputs a second signal obtained by emphasizing sound coming from a direction within a second range more than sound coming from other directions; a sound source direction detecting part that detects a sound source direction generating sound arriving at the plurality of microphones; and a directivity control part that causes the second beamformer to output the second signal if it is determined that a change angle per unit time of the direction of the sound source detected by the sound source direction detecting part is equal to or greater than a threshold while the first beamformer is outputting the first signal.
