  • Patent number: 6457043
    Abstract: A multi-party conferencing method and system determine which participants are currently speaking and send a speaker identification message to the terminals used by the participants in the conference. The terminals then display the speaker's identity on a display screen. When more than one participant is speaking at the same moment in time, the system analyzes the audio streams from the terminals and identifies a terminal associated with a dominant party. When multiple participants are using the terminal associated with the dominant party, the system identifies the speaking participant within the dominant party based on an indication received from the speaker. In one embodiment, the invention is implemented in an H.323 Internet telephony environment.
