摘要：
A system of this invention is directed to a speech processing system that efficiently performs noise suppression processing for a plurality of noise sources spreading in a lateral direction with respect to a speaker of interest. The speech processing system includes a microphone array including a plurality of microphones, each of which inputs a sound mixture including speech of a speaker of interest and noise from a noise source region including a plurality of noise sources placed in a lateral direction with respect to the speaker of interest, and outputs a mixture signal including a speech signal and a noise signal, the plurality of microphones being arranged such that a difference between respective distances from the plurality of microphones to the speaker of interest becomes different from a difference between respective distances from the plurality of microphones to the noise source region, and a noise suppressor that suppresses the noise based on the mixture signals output from the plurality of microphones.
