| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a new blind speech extraction method consisting of a minimum mean-square error short-time spectral amplitude (MMSE STSA) estimator and noise estimation based on independent component analysis. First, we handle a computer simulation using the artificial noise only in which the stationarity is controlled parametrically, and the result indicates that the proposed method is superior to the conventional methods, blind spatial subtraction array and the original MMSE STSA estimator, under the non-point-source and nonstationary noise condition. Finally, we conduct a experiment in an actual railway-station environment, and objective and subjective evaluations are shown to confirm the advantage of the proposed method in real world. | |
