We have proved that restoring the instantaneous amplitude as well as instantaneous phase on Gammatone filterbank plays a significant role for speech enhancement. However, it is still challenging topic with dereverberation since previously proposed scheme can only work in noisy environments. In this paper, we extend our previously proposed scheme to be general speech enhancement of removing the effects of noise and reverberation by restoring instantaneous amplitude and phase simultaneously. Objective and subjective experiments were conducted under various noisy reverberant conditions to evaluate the effectiveness of the extension of proposed scheme. The signal to error ratio (SER), correlation, PESQ, and SNR loss were used in objective evaluations. The
normalized mean preference score was used in subjective evaluations. The
results of both evaluations revealed that the proposed scheme could effectively improve quality and intelligibility of speech signals under noisy reverberant conditions. |
