Speech separation based on time-frequency masking has been shown to improve intelligibility of speech signals corrupted by noise. A perceived weakness of binary masking is the quality of separated speech. In this paper, an approach for improving the perceptual quality of separated speech from binary masking is proposed. Our approach consists of two stages, where a binary mask is generated in the first stage that effectively performs speech separation. In the second stage, a sparse… CONTINUE READING
