AB  - A new monaural method for the suppression of late room reverberation from speech signals, based on spectral subtraction, is presented. The problem of reverberation suppression differs from classical speech de-noising in that the -reverberation noise- is non-stationary. In this paper, the use of a novel estimator of the non-stationary reverberation noise power spectrum, based on a statistical model of late reverberation, is presented. Tests on real reverberated signals show that the proposed system yields significant reduction of reverberation together with little signal distortion.
