Solution of Underdetermined Speech Separation Problems by Combining ICA and Time-Frequency Masking Methods

Abstract (in Japanese) (See Japanese page) 
(in English) Blind source separation of speech signals has many potential applications. Toward practical applications, underdetermined problem attracts much interest. This paper proposes a new approach to solve underdetermined problem. There are three stages in the approach: 1) Separate mixtures into two independent parts; 2) Two time-frequency masks are then generated; 3) Conventional time-frequency masking method is applied to separate each source. Experimental results prove the effectiveness of the proposal. Compared with conventional methods, the proposal improves signal-to-interference ratio by at least 4~5 dB in the same setup. The advantages of the proposed method are simple array configuration, low computation cost, and higher separation performance.
