[EN] <P>PROBLEM TO BE SOLVED: To suppress a signal from a remote user that is received again by a microphone. <P>SOLUTION: A system for speech signal processing with combined noise reduction and echo compensation, comprising an adaptive beamforming signal processing means 13 configured to receive first speech signals and to acquire adaptively beaformed signals, an adaptive echo compensating means 14 configured to reduce acoustic echoes in the adaptively beamformed signals and an adaptation means, configured to simultaneously perform a combined adaptation of the adaptive beam forming means and the adaptive echo compensating means. The output microphone signal is synchronized, corresponding to the desired target signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
