PROBLEM TO BE SOLVED: To provide a sound source separation device, method and program, capable of reducing degradation of performance of sound source separation. SOLUTION: The sound source separation device separates a target sound from an interference sound occurring from a sound source differing from that of the target sound. The sound source separation device includes one or a plurality of input means of converting an input sound input from two sound input units to a sound reception signal according to prescribed sound reception processing, one or a plurality of frequency analyzer of analyzing a frequency component of each sound reception signal from each input means, one or a plurality of signal characteristic corrector of normalizing characteristics of the frequency component of the plurality of sound reception signals based on the frequency component of each sound reception signal, one or a plurality of separator of separating one or a plurality of first sound signal components obtained by suppressing the frequency component of sound arriving from a prescribed direction except an arrival direction of the target sound based on the frequency component of each normalized sound reception signal from a second sound signal component obtained by suppressing the frequency component of the sound arriving from the arrival direction of the target sound, and a remover of using each of first and second sound signal components to obtain a target sound characteristic component.
