M-B-P bilabial visemes

We all have asymmetries in our expressions. Many of these asymmetries can be observed during speech. As a specific example: When our lips press together to produce M’s, B’s, and P’s, you’ll commonly see one side of the face (lips, nose, etc.) dragged more than the other. 👄

In this video, observe how the nose and lips are pulled down more dominantly toward the right (screen right):

Leveraging these nuanced (and sometimes not-so-nuanced) idiosyncrasies can be used to create more believable digital humans and animated characters. They can also be used to decode or improve deepfakes.

We all have different degrees and patterns of signature asymmetry. Simple and subtle application of asymmetry can take your animation and 3D characters to the next level.
