| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Conventional speech enhancement in noisy environment is widely studied by modifying only an amplitude spectrum of a speech signal, while a phase spectrum which is regarded as an 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 temporal and spectral variations in a speech harmonic structure. The proposed method presents that the phase spectrum is reconstructed by using a fundamental frequency and phase distortion for speech enhancement. The objective experiment results show the improvement of speech quality and the efficiency of the proposed method. | |
