1. A method of identifying a correlation between a user and user voice, the method comprising the steps of: (a) receiving images of one or more users taken over a plurality of time periods; (b) receiving audio of voices for a plurality of time periods; and (c) correlating a voice identified in said step (b) to a user of the one or more users based on a plurality of samplings of determined positions of the user in different images and determined source locations of the voice at different times, said step (c) comprising the step of performing a first sampling of the plurality of samplings to derive a scored confidence level of an association between the voice and a user, the scored confidence level obtained by examining one or more of the following factors: i. how close the estimated position of the voice source is to the one or more users; ii. the number of voices which are being heard; iii. the closeness of the one or more users to an estimated source of the voice; iv. whether the source of the voice is estimated to be centered within a field of view of the image or closer to edges of the field of view.
