Classification: CPC G  H | IPC G  H

Claim 8:
9. An audio signal processing apparatus comprising:
an audio signal inputter configured to receive an audio signal corresponding to a voice of a talker;
an image obtainer configured to obtain an image of the talker;
a posture estimator configured to estimate posture information of the talker using the image of the talker;
a filter generator configured to generate, according to the estimated posture information, a correction filter;
an audio signal processor configured to perform filter processing on the audio signal using the generated correction filter; and
an outputter configured to output 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 by the audio signal processor 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.
