Summary

Wav2Lip is open-source code for syncing a video's lip movements to speech. Its inference script accepts supported audio files or a video file and extracts the audio automatically. The project describes compatibility with different identities, voices and languages, including CGI faces and synthetic voices, and provides training code, inference code and pretrained models. It also includes instructions for training with the LRS2 dataset; training without the visual quality discriminator takes under one day, while using it takes about two days. Wav2Lip's code is limited to personal, research and non-commercial use, and commercial use of models trained on LRS2 is prohibited. For commercial use, the repository points to Sync Labs, which offers a hosted lip-sync API and says its commercial model is higher quality than the older open-source model. Sync's plans include API access and SDKs, with features varying by plan. Hobbyist is 50.05 USD per month; Creator is 190.05 USD per month; Growth is 490.05 USD per month; and Scale is 2490.04 USD per month. Enterprise has no listed price.
