Abstract:
A sound source separation device includes a first microphone that picks up a first voice, a second microphone that picks up a second voice, a first crosstalk canceller that removes, from a voice signal of the first microphone, first crosstalk caused when the second voice is picked up by the first microphone, and a second crosstalk canceller that removes, from a voice signal of the second microphone, second crosstalk caused when the first voice is picked up by the second microphone. The first crosstalk canceller uses a voice signal in which the second crosstalk is removed from the voice signal of the second microphone to estimate and calculate a first interference signal indicative of a degree of the first crosstalk, and to remove the calculated first interference signal from the voice signal of the first microphone. The second crosstalk canceller uses a voice signal in which the first crosstalk is removed from the voice signal of the first microphone to estimate and calculate a second interference signal indicative of a degree of the second crosstalk, and to remove the calculated second interference signal from the voice signal of the second microphone.

Claim (Index 5):
The sound source separation device according to  claim 1 , further comprising:\n a third microphone that picks up a third voice; a third crosstalk canceller that removes, from a voice signal of the third microphone, third crosstalk caused when the second voice is picked up by the third microphone; a fourth crosstalk canceller that removes, from a voice signal of the first microphone, fourth crosstalk caused when the third voice is picked up by the first microphone; a fifth crosstalk canceller that removes, from a voice signal of the second microphone, fifth crosstalk caused when the third voice is picked up by the second microphone; and a sixth crosstalk canceller that removes, from a voice signal of the third microphone, sixth crosstalk caused when the first voice is picked up by the third microphone, wherein the first crosstalk canceller uses a voice signal in which the second crosstalk and the fifth crosstalk are removed from the voice signal of the second microphone to estimate the first interference signal, the second crosstalk canceller uses a voice signal in which the first crosstalk and the fourth crosstalk are removed from the voice signal of the first microphone to estimate the second interference signal, the third crosstalk canceller uses a voice signal in which the second crosstalk and the fifth crosstalk are removed from the voice signal of the second microphone to estimate and calculate a third interference signal indicative of a degree of the third crosstalk, and to remove the calculated third interference signal from the voice signal of the third microphone, the fourth crosstalk canceller uses a voice signal in which the third crosstalk and the sixth crosstalk are removed from the voice signal of the third microphone to estimate and calculate a fourth interference signal indicative of a degree of the fourth crosstalk, and to remove the calculated fourth interference signal from the voice signal of the first microphone, the fifth crosstalk canceller uses a voice signal in which the third crosstalk and the sixth crosstalk are removed from the voice signal of the third microphone to estimate and calculate a fifth interference signal indicative of a degree of the fifth crosstalk, and to remove the calculated fifth interference signal from the voice signal of the second microphone, and the sixth crosstalk canceller uses a voice signal in which the first crosstalk and the fourth crosstalk are removed from the voice signal of the first microphone to estimate and calculate a sixth interference signal indicative of a degree of the sixth crosstalk, and to remove the calculated sixth interference signal from the voice signal of the third microphone.
