Abstract
A sound source localization system and a sound source localization method. The sound source localization system includes sound capturing devices and an arithmetic unit. The sound capturing devices sense a sound source to output time domain signals. The arithmetic unit transforms the time domain signals into frequency domain signals, performs a cross spectrum process according to the frequency domain signals to determine time differences of arrival, and locates the sound source according to the time differences of arrival and locations of the sound capturing devices.
