Abstract :
A method of speech enhancement using a microphone array and the generalized eigenvalue decomposition is proposed in this paper. This method is a blind approach which does not require array calibration. The advantage of this method over the conventional blind separation based on the ICA is its fast adaptation. This is verified by a speech enhancement experiment.
