How to put metahuman face bones on another mesh for voice2face prep?

I need to use speech to face movements on a 3d model that’s not a meta human (Couldn’t find any meta humans that didn’t look like 40+ years old btw).

Can someone point me in the right direction on how to start this probably hellish task? I need to have the facial rig like a meta human has so I can use voice2face or similar solutions to have it speak audio files with its mouth and face.

Thanks.
