  • a memory comprising teleconference information which identifies a teleconference to be held, and a name database comprising a spoken name of at least one caller to the teleconference, said spoken name indexed by a caller'"'"'s identification;

    a switching matrix for selectively connecting telephone trunk lines, to which callers to the teleconference are coupled, for receipt of incoming voice signals from the telephone trunk lines to which callers to the teleconference are coupled and output of voice signals to the telephone trunk lines to which callers to the teleconference are coupled;

    a plurality of digital signal processors (DSPs) coupled to said switching matrix for mixing a plurality of audio signals received on said trunk lines to provide teleconferencing among a plurality of callers, wherein the plurality of callers teleconferenced become teleconference attendees;

    a system controller coupled to the memory and the switching matrix, said controller generating audio prompts to the callers and to the attendees to guide the callers and attendees in the operation of the teleconferencing system, one of said audio prompts requesting a caller'"'"'s identification to be entered prior to be admitted to a teleconference, and, in response to an entered caller'"'"'s identification, said controller retrieving the spoken name from the memory indexed by the caller'"'"'s identification and generating an announcement to the attendees of the teleconference using the retrieved spoken name, said announcement announcing that the caller is to join the conference, said switching matrix causing the announcement to be output on the trunk lines such that the attendees receive the announcement.
