Blender 2d lipsync script

I’m wondering if there’s a script like lipSynchro were you can use 2d mouth shape images instead of 3d shapes. It dosen’t sound to difficult to make that adjustment to lipSynchro. then again i don’t know much about programming. I’m just thinking that you could browse for the images you want to use for the specific mouth shapes.

And by the way can anyone give me a detailed explanation of how to use lipSynchro. I never really understood how to use it.
