Abstract:
A sound source localization unit determines a localized sound source direction that is a direction to a sound source on the basis of acoustic signals of a plurality of channels acquired from M (M is an integer equal to or greater than 3) sound pickup units being at different positions, and a sound source position estimation unit determines an intersection of straight lines to an estimated sound source direction, which is a direction from the sound pickup unit to an estimated sound source position of the sound source for each set of the two sound pickup units, classifies a distribution of intersections into a plurality of clusters, and updates the estimated sound source positions so that an estimation probability that is a probability of the estimated sound source positions being classified into clusters corresponding to the sound sources becomes high.

Claim (Index 6):
The acoustic processing device according to  claim 5 ,\n wherein the sound source specifying unit evaluates stability of a second cluster on the basis of a variance of the estimated sound source positions of the sound sources related to the spectra classified into each of the second clusters, and preferentially selects the estimated sound source position of a sound source of which the spectrum is classified into the second cluster having higher stability.
