Conditional End-to-End Audio Transforms
Table 2: Comparison to existing methods. We measure mean opinion score (MOS) and mel-cepstral distortion (MCD) on voice conversion and musical style transfer. Higher MOS is better. Lower MCD is better. The 95% confidence interval for TIMIT MOS and MCD values are ±0.024 and ±0.017, respectively, and for NSynth, ±0.016 and ±0.053. C-Seq2Seq is a vanilla conditioned seq-to sequence model.

We follow this same procedure for audio generated by our model by randomly selecting a fixed set of 50 test set examples. Audio generated from all baseline models on this set were rated by at least three normal-hearing human raters. A total of 10 raters participated in the study and listened to the generated audio with the same over-ear headphones. The rating scale is a 5-point numeric scale: 1. bad, 2. poor, 3. fair, 4. good, and 5. excellent. Higher values are better.
