This is a pytorch implementation of the paper: StarGAN-VC: Non-parallel many-to-many voice conversion with star generative adversarial networks https://arxiv.org/abs/1806.02169 . Note that the model architecture is a little different from that of the original paper.

• Python 3.6 (or 3.5)
• Pytorch 0.4.0
• pyworld
• tqdm
• librosa
• tensorboardX and tensorboard

Download and unzip VCTK corpus to designated directories.

mkdir ./data
wget https://datashare.is.ed.ac.uk/bitstream/handle/10283/2651/VCTK-Corpus.zip?sequence=2&isAllowed=y
unzip VCTK-Corpus.zip -d ./data

If the downloaded VCTK is in tar.gz, run this:

tar -xzvf VCTK-Corpus.tar.gz -C ./data

Preprocess data

We will use Mel-cepstral coefficients(MCEPs) here.

python preprocess.py --sample_rate 16000 \
                    --origin_wavpath data/VCTK-Corpus/wav48 \
                    --target_wavpath data/VCTK-Corpus/wav16 \
                    --mc_dir_train data/mc/train \
                    --mc_dir_test data/mc/test

Train model

Note: you may need to early stop the training process if the training-time test samples sounds good or the you can also see the training loss curves to determine early stop or not.

python main.py

Convert

For example: restore model at step 200000 and specify the source speaker and target speaker to p262 and p272, respectively.

convert.py --resume_iters 200000 --src_spk p262 --trg_spk p272

• Post some converted samples (Please find some converted samples in the converted_samples folder).
