Abstract

A system and method for speaker identification in a conference calling unit. The method identifies the speaker, locates the speaker identifier, transfers the speaker identifier to an outgoing path and sends the speaker identifier to endpoints participating in the conference call. If the endpoints have the capability of displaying caller identification, their displays will be updated dynamically with the speaker identifier in place of the caller identifier. The system includes a conference call unit. The unit has a processing unit operable to extract the caller identification of the line having the speaker and a network interface unit operable to send the caller identification to endpoints participating in the call as speaker identification.

Claims

1. A method for providing speaker identification in a conference call, the method comprising:

receiving at least two calls from a telephone network to form a conference call at a centralized conference call control unit;

determining a first conference call control unit identifier;

identifying a speaker in the conference call at the centralized conference call control unit;

extracting speaker identifier for the speaker at the conference call control unit;

overriding the first conference call control unit identifier with the sneaker identifier; and

sending the speaker identifier from the conference call control unit to endpoints participating in the conference call.

2. The method of claim 1 further comprising monitoring the conference call at the conference call control unit for changes in the speaker prior to identifying the speaker.

3. The method of claim 1 wherein extracting a speaker identifier further comprises extracting the user name information element of a public switched transmission network at the conference call control unit.

4. The method of claim 1 wherein extracting a speaker identifier further comprises extracting the user name field of a Voice over Internet packet at the conference call control unit.

5. The method of claim 1 wherein extracting the speaker identifier further comprises accessing a registry of speakers maintained by the conference call control unit.

6. The method of claim 1 wherein the conference call control unit is a public switched transmission network bridge.

7. The method of claim 1 wherein the conference call control unit is a voice over Internet multipoint control unit.

8. A conference call control unit, said unit comprising:

a processing unit operable to receive at least two calls from a network to form a conference call and locate and extract caller identification information identifying a speaker participating in a conference call; and

a network device operable to override a conference call control unit identity of the network device and send the caller identification information as the identity of the network device to endpoints participating in the conference call as speaker identification.

9. The unit of claim 8, wherein the processing unit is further to extract the caller identification from the user name identification element of a public switched transmission network.

10. The unit of claim 8, wherein the processing unit is further to extract the caller identification from a Voice-over-Internet packet.

11. The unit of claim 8, wherein the network device is further to embed the caller identification in the bearer channel of a public switched transmission network.

12. The unit of claim 8, wherein the network device is further to embed the caller identification in an outgoing packet of a voice-over-Internet transmission.

20. The conference call control unit of claim 8, wherein the processor is to receiving the call from a network through one of a public branch exchange or a multipoint control unit.

13. A method for providing speaker identification in a voice-over-internet conference call, the method comprising:

receiving at least two calls from a network at a conference call control unit;

overriding a conference call control unit identifier with a speaker identifier;

monitoring the call at a central conference call control unit for changes in the speaker;

identifying the speaker from a user name information element to determine an active speaker identifier; and

transferring the active speaker identifier through a multipoint control unit to an outgoing path.

14. The method of claim 13 further comprising receiving the active speaker identifier from the outgoing path at stations participating in the conference call and displaying the active speaker identifier at the participating stations.

15. Software for identifying an active speaker in a Voice-over-Internet conference call, the software comprising:

code for receiving at least two calls from a network at a conference call control unit;

code for overriding a conference call control unit identifier with a speaker identifier

code for monitoring the conference call at a central conference call control unit for changes in the active speaker;

code for generating an active speaker identifier in the conference call from a user name information element; and

code for transmitting the active speaker identifier to endpoints participating in the Voice-over-Internet conference call.

16. The software program according to claim 15 including code for displaying the identifier at the participating conference call endpoints.

17. A method for providing speaker identification in a voice-over-internet conference call, the method comprising:

receiving at least one two calls from a telephone network at a central conference call control unit from a network;

overriding a conference call control unit identifier with a speaker identifier;

monitoring the call at the conference call control unit for changes in the speaker;

identifying the speaker using voice spectrum analysis; and

providing an active speaker identifier based upon the voice spectrum analysis.

18. The method of claim 17, wherein the voice spectrum analysis is performed by a central unit, which provides the active speaker identifier to other stations participating in the conference call.

19. The method of claim 17, wherein the voice spectrum analysis is performed by at an endpoint of the conference call and the active speaker identifier is only provided to a display at that station.
