SPEECH SIGNAL PROCESSING WITH COMBINED NOISE REDUCTION AND ECHO COMPENSATION

摘要

The present invention relates to a speech signal processing system with a noise suppression and echo compensation in combination , speech ` signal processing system is configured to reduce acoustic echoes in the first receive a speech signal by adaptively adapting the beam formed signal is configured to derive a beam forming signal and the signal processing means from the first audio signal , adaptively beamformed signals adaptive echo compensating means, and includes adaptation means configured to perform a combined adaptation of the adaptive beamforming means and the adaptive echo compensating means at the same time .
