| description | The present invention implements audio signal processing capable of extracting the voice of each speaker even when a plurality of speakers speaks at the same time. An audio signal processing device 400 is provided with: a determination unit 401 that determines a first voice segment for a target speaker linked to a host device on the basis of an externally acquired first audio signal; a sharing unit 402 that transmits the first audio signal and the first voice segment to another device linked to a non-target speaker and receives a second audio signal and a second voice segment associated with the non-target speaker from the other device; an estimation unit 403 that estimates the voice of the non-target speaker mixed in the first audio signal on the basis of the second audio signal and the second voice segment that are received and an estimation parameter associated with the target speaker that is acquired; and a removal unit 404 that removes the voice of the non-target speaker from the first audio signal to thus create a first voice from which the voice of the non-target speaker is removed. |
