Dependencies

• Python 3.6
• Numpy
• Scipy
• PyTorch == v1.6.0
• librosa
• pysptk

• wavenet_vocoder pip install wavenet_vocoder==0.1.1 for more information, please refer to https://github.com/r9y9/wavenet_vocoder

To Run Demo

Download pre-trained models to assets

Download the same WaveNet vocoder model as in AutoVC to assets

The fast and high-quality hifi-gan v1 (https://github.com/jik876/hifi-gan) pre-trained model is now available here.

Please refer to AutoVC if you have any problems with the vocoder part, because they share the same vocoder scripts.
