SNR-based teachers-student technique for speech enhancement
Table 3: Comparison of the proposed method and the baselines.
['Method', 'PESQ', 'STOI']
We can easily notice that the proposed method (S2) achieves the best performance, whether it is PESQ or STOI. Compared to the most robust method CRN in the baseline methods, we still improved 0.143 on PESQ and 0.021 on STOI. In the scenario that contains both high SNR and low SNR noisy speeches, our proposed method based on SNR-based teachers-student technique and time-domain U-Net is undoubtedly more advantageous.
