Abstract
There is provided a sound collecting device, including: an orientation direction forming section that forms an orientation direction of a microphone array; and a control section that, when a characteristic in a frequency band of a synthesized signal obtained by synthesizing the acoustic signals corresponds to a characteristic of an acoustic signal corresponding to a sound other than a target sound, controls the orientation direction forming section such that an orientation direction that is a direction that is different than an orientation direction of the microphone array at a present point in time is formed, and, when the characteristic in the frequency band of the synthesized signal does not correspond to a characteristic of an acoustic signal corresponding to a sound other than the target sound, controls the orientation direction forming section such that the orientation direction of the microphone array is maintained.
