Single channel speech separation based on sinusoidal modeling

We present an approach of single channel speech separation based on sinusoidal modeling and multi-scale product analysis. To construct the sinusoidal model of speech, we need to determine three parameters which are namely frequency, amplitude and phase. For fundamental frequency determination, we apply an effective method based on multi-scale product analysis. For amplitude estimation, we adopt an iterative peak picking algorithm. This approach effectively estimates multi-pitch of the desired speaker in a multiple speaker context.
