- W985959438 abstract "Aim at the underdetermined convolutive mixture model,a blind speech source separation method based on nonlinear time-frequency masking was proposed,where the ap- proximate W-disjoint orthogonality(W-DO)property among independent speech signals in time-frequency domain is utilized.In this method,the observation mixture signal from multi- microphones is normalized to be independent of frequency in the time-frequency domain at first,then the dynamic clustering algorithm is adopted to obtain the active source information in each time-frequency slot,a nonlinear function via deflection angle from the cluster center is selected for time-frequency masking,finally the blind separation of mixture speech signals can be achieved by inverse STFT(short-time Fourier transformation).This method can not only solve the problem of frequency permutation which may be met in most classic frequency-domain blind separation techniques,but also suppress the spatial direction diffusion of the separation matrix.The simulation results demonstrate that the proposed separation method is better than the typical BLUES method,the signal-noise-ratio gain(SNRG)increases 1.58 dB averagely." @default.
