Claim 0:
1. An audio signal processing method comprising:
receiving an audio signal corresponding to a voice of a talker;
obtaining an image of the talker;
estimating posture information of the talker using the image of the talker;
generating a correction filter according to the estimated posture information;
performing filter processing on the audio signal using the generated correction filter; and
outputting the audio signal on which the filter processing has been performed,
wherein:
the estimated posture information includes a direction in which a face of the talker faces,
the generated correction filter is configured to perform beamforming on the audio signal, and, in the filter processing performed on the audio signal using the generated correction filter, a directional strength of the beamforming is controlled according to the direction in which the face of the talker faces, and
the directional strength of the beamforming is sharpest when the face of the talker is facing right in front.
