VoiceCraft: Zero-Shot Speech Editing and Text-to-Speech in the Wild

Demo Paper

TL;DR: VoiceCraft is a token infilling neural codec language model, that achieves state-of-the-art performance on both speech editing and zero-shot text-to-speech (TTS) on in-the-wild data including audiobooks, internet videos, and podcasts.

To clone or edit an unseen voice, VoiceCraft needs only a few seconds of reference.

TODO

The TODOs left will be completed by the end of March 2024.

• Codebase upload
• Environment setup
• Inference demo for speech editing and TTS
• Upload model weights
• Training guidance
• Upload the RealEdit dataset

Environment setup

conda create -n voicecraft python=3.9.16
conda activate voicecraft

pip install torch==2.0.1 torchaudio==2.0.2 # this assumes your system is compatible with CUDA 11.7, otherwise checkout https://pytorch.org/get-started/previous-versions/#v201
apt-get install ffmpeg # if you don't already have ffmpeg installed
pip install -e git+https://github.com/facebookresearch/audiocraft.git@c5157b5bf14bf83449c17ea1eeb66c19fb4bc7f0#egg=audiocraft
apt-get install espeak-ng # backend for the phonemizer installed below
pip install phonemizer==3.2.1
pip install tensorboard
pip install datasets==2.12.0
# install MFA for getting forced-alignment, this could take a few minutes
conda install -c conda-forge montreal-forced-aligner=2.2.17 openfst=1.8.2 kaldi=5.5.1068
# conda install pocl # above gives an warning for installing pocl, not sure if really need this

# to run ipynb
conda install -n voicecraft ipykernel --update-deps --force-reinstall
