Single-channel Speech Dereverberation via Generative Adversarial Training
Table 5: Comparison of dereverberation systems with online processing.
['3 System', 'PESQ Room D', 'PESQ Room E', 'SRMR Room D', 'SRMR Room E']
Compared with utterance-level DeReGAT, the performance of DeReGAT-online degrades. Compared with reverberant speech, the worse PESQ of DeRe-10 shows heavy distortion in speech quality. The comparable performance of DeRe-40 with DeReGAT makes it capable of serving as an online system, where the overall delay consists of model’s feed-forward time and the size of mini-batch. The speech dereverberated by DeRe-20 sounds better, and DeRe-40 generates the most consistent speech among all online systems.
