| Abstract;Audio-teleconferencing, video-teleconferencing, and hands-free telecommunication using personal computers in noisy offices are on the increase. To achieve hands-free telecommunication that is pleasant even in such environments, we have developed technology for an echo canceller that includes noise reduction. Here we describe a mechanism for suppressing ambient noise and the echoes embedded in that noise, and we introduce practical devices that implement that mechanism. (author abst.) |
