Lifetime Upgradeable Computer Interface is designed to provide a blendshape model that allows for an avatar to have lips animated and speak from an AI engine such as my GPT-2-Speech-Output repo.
Below is a software called Lipsync Pro - there is also a free version as far as I can tell but I was unable to find it in the asset store - I purchased this for $35 and found it worked great bridging the gap between GPT-2 and the lip movements needed to make her seem "real"
