| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a method of restoring the instantaneous amplitudes and phases using Kalman filter with linear prediction from a noisy reverberant signal for speech enhancement. Recent studies have shown that the phase spectrum in short time Fourier transform plays an important role for speech enhancement. We thus have previously proposed the method of restoring the instantaneous amplitudes and phases simultaneously in noisy environment based on this fact. In this paper, we extend our previous method to be general speech enhancement in real environments by removing the effects of noise and reverberation simultaneously. Objective experiments were conducted in various noisy reverberant environments to evaluate the effectiveness of the proposed scheme by using signal to error ratio (SER), correlation, perceptual evaluation of speech quality (PESQ), and SNR loss. Results showed that the proposed method can effectively improve these objective measurements in noisy reverberant environments, compared with typical methods such as Wiener filtering method and minimum mean square error short-time spectral amplitude (MMSE-STSA) method. | |
