| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Frequency domain independent component analyis has received much attention from many industries for high performace speech enhancement applications. When this method would be applied to mobile devices, it is important to develop a fewer computational method.A speech signal consists of a set of some predominant frequency bands, therefore, a separation matrix could be learned on limited frequency bands, and the null-beamformer could be an alternative separation matrix on the other bands. Outputs of the null-beamformer has distortion caused by attenuation in the low frequency region, however, a frame-wise spectral softmask based on output signals via the alternative separation matrix mitigates this problem. | |
