SNR-based teachers-student technique for speech enhancement
Table 1: The PESQ and STOI of the proposed method at different SNRs and different noises.
['Noise', 'Target', 'PESQ Seen', 'PESQ Seen', 'PESQ Seen', 'PESQ Seen', 'PESQ Seen', 'PESQ Unseen', 'PESQ Unseen', 'PESQ Unseen', 'PESQ Unseen', 'STOI Seen', 'STOI Seen', 'STOI Seen', 'STOI Seen', 'STOI Seen', 'STOI Unseen', 'STOI Unseen', 'STOI Unseen', 'STOI Unseen']
The “Noisy” lines in the table represent the noisy speech, and the “Enhanced” lines represent the enhanced speech using the proposed method. The “Seen” columns mean the SNRs exist in the training dataset of the student model while the “Unseen” columns indicate the SNRs that do not exist in the training dataset of the student model.
