20 Claims

1. A method of processing audio signals, comprising:

receiving an audio signal via a plurality of microphones;

receiving an image associated with a frame of the audio signal;

detecting one or more faces in the received image;

selecting a number (N) of target faces among the one or more faces detected in the received image;

determining a respective direction of each of the N target faces relative to the plurality of microphones; and

selectively steering a beam associated with a multi-channel beamformer toward a direction-of-arrival (DOA) of the audio signal based at least in part on the directions of the N target faces.
