Abstract

A method and system to index the content of conferences. It includes identifying each such conference participant producing a sound, capturing an image of each such conference participant, and with correlating the images of the conference participants with audio segments of an audio recording, that is the segments corresponding to the audio produced by the conference participant. The indexing system includes a sound recording mechanism, at least one identifier of locations of conference participants, a camera, an image storage device, a processor for associating the still images captured by the camera to the sound recorded by the sound recording mechanism thereby correlating still images of the conference participants to audio segments produced by the conference participants, and a graphical user interface which allows easy access to stored sound, images, and correlated data. It may also include an aiming device for pointing the camera at the person speaking.
