Can we steal your vocal identity from the Internet?: Initial investigation of cloning Obama’s voice using GAN, WaveNet and low-quality found data
Table 4: Average SNR in dB estimated with NIST tool for the results of the different speech enhancement models.
['SOURCES', 'average SNR (dB)']
In particular, training using noisy data (i.e., “n”, “nr”, and their mixtures) was considerably more effective than training using the other two possibilities (i.e., “r” and “DR”). This is attributed to the fact that their use reduces the noise levels in the signal, which is what the SNR measure targets. Their use may not actually improve the perceptual quality of the voice signals.
