Conclusions

We proposed an algorithm which enables to detect the number of speakers, accurate $ F_0$s and spectral envelopes from co-channel input simultaneous speech signals with spectral domain procedure. It showed a high performance for speech signals of both single speaker and two speakers. Still, several improvements are prospective by considering temporal continuity of $ F_0$ contour (e.g., introducing Fujisaki model), incorporating variance into the model parameters also as a variable or by introducing a priori probability distribution of the model parameters, etc.
