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.
