| Research Abstract |
The purpose of this research is to develop a blind source separation (BSS) system restoring a target speech sound with high quality by removing noise and reverberation, and to establish the required signal processing technique. From a viewpoint of sparseness of speech sounds, several approaches have been proposed to solve the problems inherent to the current BSS system based on independent component analysis. These approaches are expected to be bases for extracting the target speech immediately in a real-time manner.
