ABSTRACT:
A voice conference apparatus includes: a communication unit that transmits and receives a first voice signal to and from another apparatus via a network; an output unit that reproduces the first voice signal received by the communication unit and outputs the reproduced first voice signal as a first voice; an input unit that collects the first voice and a second voice generated by a voice source, as a second voice signal; a separating unit that separates the second voice signal into a third voice signal originated from the first voice and a fourth voice signal originated from the second voice; and a selecting unit that selects one of the third voice signal and the fourth voice signal. The communication unit transmits the one of the third voice signal and the fourth voice signal selected by the selecting unit to the other apparatus.
