PROBLEM TO BE SOLVED: To provide a specific voice suppressor which suppresses voice of a specific speaker in the mixture voice signal, a specific voice suppression method and a program.SOLUTION: A specific voice suppressor comprises: a sound source separation unit which generates, when i is an element of {1,...,M}, a voice estimated value Sof a speaker i and a power parameter Pcorresponding to a voice power of the speaker i from a voice signal including voice of M speakers; a loud voice determination unit which compensates, when j is an element of {1,...,M} other than i, the voice power Pof the voice of the speaker i specified by the power parameter Pusing a distance d(U, L) between a microphone that is used when recording the voice signal and the speaker i, generates the compensated voice power P, and calculates a loud voice degree Ethat represents a loud voice degree of the speaker i to the other speakers j using the power P; and a mixture voice signal generation unit which combines the voice estimated value Sother than the estimated value Scorresponding to the loud voice degree Ethat is a threshold A or more to generate a mixture voice signal. |
