This repository provides a PyTorch implementation of SpeechSplit, which enables more detailed speaking style conversion by disentangling speech into content, timbre, rhythm and pitch.
This is a short video that explains the main concepts of our work. If you find this work useful and use it in your research, please consider citing our paper.

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.
Run demo.ipynb
Please refer to AutoVC if you have any problems with the vocoder part, because they share the same vocoder scripts.
Download training data to assets.
The provided training data is very small for code verification purpose only.
Please use the scripts to prepare your own data for training.
