1. A computer-implemented process for finding the location of a person speaking using signals output by a microphone array having a plurality of audio sensors, comprising using a computer to perform the following process actions: inputting the signal generated by each audio sensor of the microphone array; distinguishing the portion of each of the array sensor signals that contains human speech data from non-speech portions; reducing noise attributable to stationary sources on those portions of the array sensor signals that contain human speech data; and locating the position of the person speaking using a time-delay-of-arrival (TDOA) based sound source localization (SSL) technique on those portions of the array sensor signals that contain human speech data.
