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 5):
The acoustic processing device according to  claim 1 , further comprising:\n a sound source separation unit configured to separate acoustic signals of the plurality of channels into sound source-specific signals for respective sound sources; a frequency analysis unit configured to calculate a spectrum of the sound source-specific signal; and a sound source specifying unit configured to classify the spectra into a plurality of second clusters, determine whether or not the sound sources related to the respective spectra classified into the second clusters are the same, and select the estimated sound source position of the sound source determined to be the same in preference to the sound source determined not to be the same.
