Claim:
1. A videoconferencing endpoint, the endpoint comprising: at least one processor, a predetermined number of microphones and at least one camera, each in signal communication with the processor; at least one non-transitory computer readable storage medium in signal communication with the processor; at least one program module, stored on the non-transitory computer readable storage medium and operable, upon execution of the processor to: receive audio information via the predetermined number of microphones for a predetermined period during a teleconferencing session, the audio information corresponding to one or more angles with respect to the microphones from within a location of the teleconferencing session; analyze the received audio information according to at least one algorithm to determine at least one candidate angle, the candidate angle corresponding to a possible location of an active talker, wherein the algorithm gives greater weight to lower frequency bands than to higher frequency bands from within the received audio information; receive motion information via at the least one camera; and analyze the candidate angle with respect to the received motion information to determine whether the candidate angle corresponds to an active talker.
