A gain factor adapted by both the intra-frame masking properties of the human auditory system and the inter-frame SNR variation is proposed to enhance a speech signal corrupted by additive noise. In this article we employ an averaging factor, varying with time–frequency, to improve the estimate of the a priori SNR. In turn, this SNR estimate is utilized to adapt a gain factor for speech enhancement...
A speech enhancement algorithm adapted by both intra- frame masking properties of the human auditory system and inter-frame SNR variation is proposed to enhance a speech signal corrupted by colored noise. Herein, we employ a gain factor adapted by the SNR variation to reduce the spectral variation over successive frames, so the effect of musical residual noise can be mitigated. In addition, the masking...
