Wav2Lip: Accurately Lip-syncing Videos and OpenVINO#
This Jupyter notebook can be launched after a local installation only.
Lip sync technologies are widely used for digital human use cases, which enhance the user experience in dialog scenarios.
Wav2Lip is an approach to generate accurate 2D lip-synced videos in the wild with only one video and an audio clip. Wav2Lip leverages an accurate lip-sync “expert” model and consecutive face frames for accurate, natural lip motion generation.
teaser#
In this notebook, we introduce how to enable and optimize Wav2Lippipeline with OpenVINO. This is adaptation of the blog article Enable 2D Lip Sync Wav2Lip Pipeline with OpenVINO Runtime.
Here is Wav2Lip pipeline overview:

Installation Instructions#
This is a self-contained example that relies solely on its own code.
We recommend running the notebook in a virtual environment. You only need a Jupyter server to start. For details, please refer to Installation Guide.

Convert the model to OpenVINO IR#
You don’t need to download checkpoints and load models, just call the
helper function download_and_convert_models. It takes care about it
and will convert both model in OpenVINO format.
