Claim 6:
7. A method for acoustic echo cancellation, comprising:
determining a location of a person in a room based in part on camera information;
capturing an audio signal received from the location of the person using a beamformer;
determining a room impulse response based in part on the audio signal captured from the location of the person;
providing an output of the beamformer as an input to an echo canceler that performs acoustic echo cancellation on the audio signal received from the location of the person based in part on the room impulse response, wherein the room impulse response is an acoustic echo cancellation parameter;
performing the acoustic echo cancellation on a number of channels that are outputted from the beamformer, wherein the number of channels corresponds to a number of persons detected in the room based in part on the camera information; and
transmitting the audio signal having the canceled acoustic echo.
