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. A speech processing system comprises: at least one hardware processor configured to implement: a linear microphone array (201, 701) comprising a plurality of microphones (211, 212), arranged on a straight line, each of which inputs speech of a speaker (220) of interest and noise from a noise source region (310, 320) comprising a plurality of noise sources, and outputs a mixture signal comprising said speech and said noise; and a noise suppressor (430) that suppresses said noise based on said mixture signals, wherein a direction of arranging the plurality of microphones (211, 212) in said linear microphone array (210, 701) is determined such that said straight line is perpendicular to a longitudinal axis of said noise source region (310, 320), and a distance, between said linear microphone array (201, 701) and said noise source region (310, 320), and a tilt of a placement plane of said microphone array (201, 701) are adjusted so as to decrease differences between respective distances from each of noise sources in said noise source region (310, 320) to the plurality of microphones (211, 212) in said linear microphone array (201, 701
