I am very much fascinated by this virtual avatar talking thing. I tried video-retalking https://github.com/OpenTalker/video-retalking just to see how far I can make it work to make a talking avatar but it is tremendously difficult. But this holds tremendous possibilities and I hope it can be eventually cheaper to run such models. I know this is far superior and probably a lot different but I hope to find open source solutions like Lemon Slice someday that I can experiment with.

Nice! Thanks for sharing. I hadn't seen that paper before. Looks like they take in a real-world video and then re-generate the mouth to get to lip synch. In our solution, we take in an image and then generate the entire video.

I am sure they will have open source solutions for fully-generated real-time video within the next year. We also plan to provide an API for our solution at some point.
