Abstract
A method for auto focus on a speaker during a communication session includes receiving video captured of a scene that includes a plurality of images of participants to the communication session, identifying the plurality of images of the participants in the video captured of the scene, recognizing audio from at least one of the participants, detecting facial movement in one of the images of the plurality of images and equating the recognized audio to the detected movement in the one of the images of the plurality of images. The method also includes selecting the one of the images of the plurality of images as a speaker based on the equated recognized audio to the detected movement in the one of the images, zooming in on the speaker and filtering out a remainder of the images of the plurality of images.
