Abstract

Recently, time-frequency masking algorithm has been interested as a method of BSS (blind source separation) of speech mixtures. It is based on the property of speech signals called W-disjoint orthogonality. This paper aims to realize the omnidirectional BSS system with small computational cost and to provide high separation performance even for closely located sound sources. The time-frequency masking is applied to equilateral triangular array where the three delay estimates from each microphone pairs are obtained. These data are integrated to separate speech signals. To prove the efficiency of the method, some experimental results in real environment are shown.
