Building an AI Vtuber

Hello fellow AI enthusiasts! I recently discovered the AI Vtuber Neuro-Sama, while there are a lot of videos of people who have built something like her, I can’t find an in-detail tutorial on how to build it. I’m not a computer expert, and I don’t claim to be, but I have a lot of determination and interest in this. So if anyone knows any highly detailed tutorials on how to build something similar to Neuro-Sama, I would very much appreciate that. Have a good Fourth of July! P.S. I deleted and reposted because I realized the title was not correct.
