TRANSLATE REVERBERATED SPEECH TO ANECHOIC ONES: SPEECH DEREVERBERATION WITH BERT
Table 3: PESQ of CNN1d-BERT with Griffin-Lim 32 iterations (GL) and Neural vocoder (NV)
['[ITALIC] T60', '0.3', '0.6', '0.9']
Griffin-Lim with 32 iterations obtains an real time factor (RTF) of 0.319, whereas Parallel WaveGan on GPU obtains an RTF of 0.027. Decoding with Parallel WaveGan is about 10 times faster than Griffin-Lim with comparable performance. However, decoding using a neural vocoder is rarely considered in the context of speech dereverberation and denoising.
