Time-frequency masks for monaural speech separation: A comparative review

In this paper we present a comparative analysis of different time-frequency (T-F) masking techniques used for single channel speech separation (SCSS). We survey T-F masking concept and compare different types of masks in different criteria. The comparison is conduct theoretically by mathematical study and numerically by objective and subjective assessment. Also, we study the effect of the masking techniques on the perceptual quality of speech and their ability to separate a target speech from monaural mixing.
