摘要

PROBLEM TO BE SOLVED: To provide a sound source position estimation device with which it is possible to estimate and record who is talking and when and where in a prescribed space.SOLUTION: In a sound source position estimation device 2000, a sound source direction estimation unit specifies a direction in which a sound arrives at a plurality of microphone arrays 1052.1-4 on the basis of physical relationship between each of signals on a plurality of channels from the plurality of microphone arrays and each microphone included in the microphone arrays. A voiced section estimation unit estimates a person who is uttering on the basis of a set of directions in which the sound specified by each of different microphone arrays among the plurality of microphone arrays 1052.1-4 arrive and the position information of the person.SELECTED DRAWING: Figure 1
