In lip sync animation, why is it important to animate the tongue and teeth, not just the lips?

Accepted Answer

Many phonemes require visible tongue position and teeth shape to be believable in close-up

Answer

In facial motion capture retargeting, what challenge arises when transferring data between actors and characters with different proportions?
