An unofficial PyTorch implementation of VALL-E(Neural Codec Language Models are Zero-Shot Text to Speech Synthesizers).

We can train the VALL-E model on one GPU.

Inference: In-Context Learning via Prompting

see LibriTTS/Inference

Demo

Broader impacts

Since VALL-E could synthesize speech that maintains speaker identity, it may carry potential risks in misuse of the model, such as spoofing voice identification or impersonating a specific speaker.

To avoid abuse, Well-trained models and services will not be provided.

Troubleshooting

• SummaryWriter segmentation fault (core dumped)
  • LINE tb_writer = SummaryWriter(log_dir=f"{params.exp_dir}/tensorboard")
  • FIX https://github.com/tensorflow/tensorboard/pull/6135/files

  file=`python  -c 'import site; print(f"{site.getsitepackages()[0]}/tensorboard/summary/writer/event_file_writer.py")'`
  sed -i 's/import tf/import tensorflow_stub as tf/g' $file
