Claim:
1. A method for determining a location of an active speaker, the method comprising: from an image capture device, receiving image data of a room in which the active speaker and at least one inactive speaker are located; using the image data, generating a three dimensional model of at least a portion of the room; from a first microphone array at the image capture device, receiving first audio data from the room; from a second microphone array that is laterally spaced from the image capture device, receiving second audio data from the room; using the three dimensional model, determining a location of the second microphone array with respect to the image capture device; using at least the first audio data, the second audio data, the location of the second microphone array, and an angular orientation of the second microphone array, determining an estimated location in the three dimensional model of the active speaker; using the estimated location of the active speaker to compute a setting for the image capture device; and outputting the setting to control the image capture device to highlight the active speaker.
