Abstract (in Japanese) (See Japanese page) 
(in English) Conventionally the speech enhancement in noisy environment is widely studied by modifying only the amplitude spectrum of the speech signal, while the phase spectrum which is regarded as the unimportant feature in speech enhancement field is ignored.However, it has recently reported that the phase spectrum plays an important role in the intelligibility of the speech.
This paper proposes the speech enhancement with a phase reconstruction based on a harmonic structure of a speech.The proposed method presents that the phase spectrum is reconstructed along time and frequency and is applied to the speech enhancement.The objective experiment results show the improvement of speech quality and the efficiency of the proposed method.
