| Abstract(in English) | The purpose of this study is to enhance speeches in multiple speaker condition. We proposed the speech enhancement system for the harmonic signals such as speeches. The proposed system used information of fundamental frequency and power of speeches. It was not enough to track the pitches of same speaker by influence of other speeches. We consider the problem of connection for pitches will be relaxed by information of sound source direction. If the pitches of each syllable is connected, this system can be useful for pre-emphasis system for speech recognition. The results show the better performance for the pre-enhancement system. |
