Thank you!
Here you can find the Lip Sync Project by Synthesia: https://www.fxguide.com/fxfeatured/synthesia-lip-sync/

In GitHub, there are various repositories and experimentations, especially if you look for Face2Face method: https://github.com/topics/face2face

There are also Face2Face applications available — the results aren’t such convincing as in Ctrl+Shift+Face videos, but for the main conception, it can also be useful.
