Abstract :
This paper proposes a dereverberation system for speech enhancement using modified linear prediction (LP) residual in the reverberant room condition. We obtain a delay-and-sum beamformer and new LP residual signal using modified LP residual combination, which derived from weighting of the LP residual and the Hilbert transform of LP residual.
