  • Acoustic processing device, acoustic processing method, and program
    Patent number: 10356520
    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.
