抄録

An audio teleconferencing set with an acoustic echo canceller has been developed which eliminates acoustic coupling and echo feedback, and allows full open and life-like conversation. It is designed to be used with a multiple microphone system containing gain switching. The echo canceller is provided with memories for multiple echo paths so that filter coefficients may be updated when an echo path is switched due to a change of actuated microphone when speaker alternation occurs. Delay processing time of 0. 5 sec. for 7 kHz band signal is achieved by using digital signal processor chips.
