Abstract

The invention relates to an apparatus and method for identifying teleconference participants. More particularly, the invention relates to a conference system that includes an initialization means for initializing a call between participants located in at least two remote stations and an identification means for identifying one of the participants in one remote station responsive to a request from another of the participants in another remote station. The initialization means comprises table means for creating a table associating each of the participants to a position in a particular remote station and including a recorded voice segment of each of the participants. The identification means uses the table to identify the participant last to speak by looking up the position of the last speaker on the table and playing back the recorded voice segment of the participant associated with that position.
