An adaptive a priori SNR estimator for perceptual speech enhancement

An adaptive a priori SNR estimator for perceptual speech enhancement

Abstract In this paper, an adaptive averaging a priori SNR estimation employing critical band processing is proposed. The proposed method modifies the current decision-directed a priori SNR estimation to achieve faster tracking when SNR changes. The decision-directed estimator (DD) employs a fixed w...
