This sound collection system S has: a microphone array 1 that includes a plurality of microphones 2; a first beamformer 152 that outputs a first signal in which a sound signal based on a sound arriving from a direction within a first range is emphasized more than a sound signal based on a sound arriving from another direction, among a plurality of sound signals based on sounds that have arrived at the plurality of microphones 2; a second beamformer 153 that outputs a second signal in which a sound signal based on a sound arriving from a direction within a second range is emphasized more than a sound signal based on a sound arriving from another direction, among the plurality of sound signals; a sound source direction detection unit 151 that detects the direction of sound sources generating the sounds arriving at the plurality of microphones 2; and a directivity control unit 155 that causes the second beamformer 153 to output the second signal if a change angle per unit time in the direction of the sound sources detected by the sound source direction detection unit 151 is judged to be at least a threshold value while the first beamformer 152 is outputting the first signal.
