摘要

The system of the present invention relates to a speech processing system that efficiently performs noise suppression processing on a plurality of noise sources that spread laterally toward a speaker of interest. The speech processing system inputs a mixed sound of noise from a noise source area including a plurality of noise sources arranged side by side toward the speaker of interest and the speech of the speaker of interest, and mixes the voice signal and the noise signal. A plurality of microphones that output signals, the microphones arranged side by side so that the difference between each microphone and each speaker of interest is different from the distance between each microphone and the noise source area And a noise suppression unit that suppresses noise based on mixed signals output from a plurality of microphones.
