This is just a quick lip-sync test using Blender, and Unity with the Salsa lip-sync asset. I re-used the same mesh for all three characters, swapping out the image texture. I used two blendshapes for the mouth, but did several different combinations of them for visemes. I also used three other blendshapes for brows, nose, and eyes to add a little more life.
