PROBLEM TO BE SOLVED: To provide a sound source estimation device, method, and program capable of estimating a sound source more accurately and to provide a moving body using the same.SOLUTION: The sound source estimation device uses observation signals acquired by microphones 11 and 12 to estimate a direction of a sound source and includes: a noise estimator 23 which estimates noise components included in the observation signals; a mask generation unit 24 which generates a mask M(ω,t) on the basis of the noise components estimated by the noise estimator 23; a reliability generation unit 25 which calculates reliability (t) of the mask generated by the mask generation unit 24; a CSP coefficient calculation unit 26 which calculates a CSP coefficient corrected by the mask and the reliability of the mask; and a direction estimation unit 28 which estimates the direction of the sound source on the basis of the CSP coefficient. |
