MULTIPOINT CONFERENCE DEVICE, MULTIPOINT CONFERENCE CONTROL PROGRAM, AND MULTIPOINT CONFERENCE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multipoint conference device with which it is possible to exhibit an echo cancellation function without being affected by an individual difference in the function or performance of a conference terminal.SOLUTION: This multipoint conference device has: voice synthesis processing means for synthesizing voice signals received from conference devices in first to N-th conference devices that satisfy a prescribed condition and outputting a synthesized voice signal; transmission means for transmitting the synthesized voice signal to an n-th conference device (n is one of 1 to N); reception means for receiving an n-th voice signal; pseudo-echo generation means for generating a pseudo-echo signal that imitates an echo component based on the synthesized voice signal included in the n-th voice signal; and echo component deletion means for deleting the pseudo-echo signal from the n-th voice signal.SELECTED DRAWING: Figure 1
