We have proposed a new method of extracting the desired speech from noisy speech precisely even in waveforms by using constraints on the continuity of the instantaneous phases as well as constraints on the continuity of the instantaneous amplitudes and the fundamental frequency.
To show that the proposed model can extract real speech from noisy speech precisely even in waveforms, we demonstrated one evaluation and three simulations of segregating two acoustic sources. The result of evaluation showed that all constraints related to the four regularities are useful in order to segregate the desired vowel from noisy vowel. The results of the three simulations showed that the proposed method can segregate the desired vowel from noisy vowel precisely even in waveforms. It was also shown that the proposed method can precisely segregate the desired signal from the simultaneous signals using the instantaneous amplitude and phase.
