Abstract |
AB |
[EN] The present invention relates to a system for speech signal processing with combined noise reduction and echo compensation, comprising an adaptive beamforming signal processing means (Fig.1,w(k);Fig.2 w c (k),B(k) and w a (k)) configured to receive first speech signals (x(k),M) and to derive adaptively beamformed signals from the first speech signals, an adaptive echo compensating means (Fig.1,Fig.2,a(k)) configured to reduce acoustic echoes in the adaptively beamformed signals and an adaptation means configured to simultaneously perform a combined adaptation of the adaptive beamforming means and the adaptive echo compensating means. |
