Abstract
A sound processing apparatus includes an acquisition unit configured to acquire sound signals collected by a microphone array, a sound source localization unit configured to determine a sound source direction on the basis of the sound signals acquired by the acquisition unit, and a sound source identification unit configured to identify a type of sound source on the basis of a sound model indicating a dependence relationship between sound sources, in which the sound model is represented by a probabilistic model expression including sound source localization as an element.
