We previously proved that restoring the instantaneous amplitude as well as instantaneous phase on the output from Gammatone filterbank plays a significant role in speech enhancement. However, dereverberation is still a challenge since the previously proposed scheme can only work in noisy environments. In this paper, we extend our previously proposed scheme to general speech enhancement for removing...
This paper proposes a restoration scheme for the instantaneous amplitudes and phases in sub-bands by using a Kalman filter with linear prediction (LP). A few important studies have already proved that the phase spectrum in the short-time Fourier transform plays an important role in speech enhancement. Thus, the proposed scheme concentrates on simultaneously restoring both instantaneous amplitudes...
