Abstract

A system and method for determining a speaker'"'"'s position and a generating a display showing the position of the speaker. In one embodiment, the system comprises a first speakerphone system and a second speakerphone system communicatively coupled to send and receive data. The speakerphone system comprises a display, an input device, a microphone array, a speaker, and a position processing module. The position processing module is coupled to receive acoustic signals from the microphone array. The position processing module uses these acoustic signals to determine a position of the speaker. The position information is then sent to other speakerphone system for presentation on the display. In one embodiment, the position processing module comprises an auto-detection module, a position analysis module, a tracking module and an identity matching module for the detection of sound, the determination of position and transmission of position information over the network. The position processing module comprises a position display module and a position translation module for receiving position information from the network and generating a user interface for display. The present invention also includes a method for determining speaker position and presenting position information.

17. The method of claim 5 wherein presenting the determined position at the second site comprises:

presenting on the display at the second site a first stored or live image corresponding to the first speaker, the first stored or live image presented as it would appear from the vantage point of the microphone array at the first site.

19. The method of claim 1 further comprising:

determining a distance from the determined position;

generating an audio signal from the received acoustic signals; and

using the determined distance to modify an audio level of the audio signal. presenting the determined position on a display at the second site.

20. A system for facilitating speaker identification on a call, the system comprising:

a first phone system having a microphone array having a plurality of microphones, a position processing module and a transmitter for determining a position of the first speaker based on acoustic signals received by the microphone array and outputting the determined position, the position processing module coupled to the microphone array; and
