| Abstract(in English) | A stereo echo canceller is required for a stereo teleconferencing system. The main problems are that the adaptive filters often misconverge or, if not, convergence speeds are very slow because of the cross-correlation between stereo signals. Several pre-processing methods which decorrelate stereo signals in order to overcome this problem have been proposed. But these methods introduce distortion resulting in low speech quality. In this paper, we focus on tiny movement of far-end talker and propose a new method of decorrelating with stereo signals without any confusion in sound image localization. We show that convergence can be further improved and speech quality maintained by optimizing using the characteristics of auditory perception. |
