Abstract

In many speech applications, the target signal is corrupted by highly correlated noise sources. Separating desired speaker signals from the mixture is one of the most challenging research topics in speech signal processing. This paper proposes a binaural system combined with a monaural incoherent post processor for speech segregation. The proposed binaural system is based on spatial localization cues: INTERAURAL TIME DIFFERENCES (ITD) and INTERAURAL INTENSITY DIFFERENCES (IID). A target speech is separated from interfering sounds by estimating time-frequency binary and RATIO MASKs. The binary mask is estimated using the multi-level extension of the Otsu thresholding algorithm used in image segmentation. ITD and IID are important features for mask estimation in low and high frequencies, respectively. The RATIO MASK is estimated using the incoherent monaural SPEECH SEPARATION system as the post processing stage. Systematic evaluations show that the proposed system can separate the target signal with acceptance quality.
