Abstract In this paper, a weighting factor for alleviating the speech distortion and reducing the residual noise in the speech enhancement system is derived. The function of weighting factor is to keep the energy of residual noise lower than the noise masking threshold and the speech distortion smaller than the residual noise. With Matlab language, the emulational results show the enhancement speech using the proposed method sounds more natural and leads to a significant reduction of the unnatural structure of the residual noise while alleviating the speech distortion.
