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. |

DETAILED DESCRIPTION A multi-party conferencing method and system in accordance with our invention identify the participants who are speaking and send an identification of the speaking participants to the terminals of the participants in the conference.
When more than one participant is speaking at the same moment in time, the method and system analyze the audio streams from the terminals and identify a terminal associated with a dominant party.
When multiple participants are using the terminal associated with the dominant party, the method and system identify the speaking participant within the dominant party based on an indication received from the speaker.
In one embodiment, the system is implemented in an H.
323-compliant telephony environment.
A multipoint control unit controls the mixing of audio streams from H.
323-compliant terminals and the broadcasting of an audio stream to the terminals.
A speaker identifier service cooperates with the multipoint control unit to identify a speaker and to provide the identity of the speaker to the terminals.
Before commencing the conference, the participants register with the speaker identifier service.
This involves identifying which terminal the participant is using, registering the participant's name and, for those terminals that are used by more than one participant, identifying which speaker indication is associated with each participant.
During the conference, the multipoint processor in the multipoint control unit identifies the terminal associated with the dominant speaker and broadcasts the audio stream associated with that terminal to all of the terminals in the conference.
In addition, the multipoint processor sends the dominant speaker terminal information to the speaker identifier service.
The speaker identifier service compares the dominant speaker terminal information with the speaker identification information that was previously registered to obtain the identification information for that speaker.
If more than one speaker is associated with the dominant terminal, the speaker identifier service compares the speaker indication (provided it was sent by the actual speaker) with the speaker identification information that was previously registered
