FaceBot uses the Preston-Blair simple phoneme set to sync animation to audio using blendshapes, with best results achieved by creating a model phoneme config file mapping blendshapes to phoneme shapes. While using matching blendshape names allows AutoSync to work without a config file, it prevents adjusting animation with the facial rig since phonemes are not part of its blendshape set structure.

blendshape phoneme structure & order
FaceBot AutoSync uses the Preston-Blair
simple phoneme set. This works best for
cartoon style animation.
For best results create a model phoneme
config file, setting a keyframe using existing
blendshapes for defined phoneme shapes
on next page. If your model has a blend
shapes matching the required name
mapping, AutoSync will use those without
the need for a model config file. However,
you will not be able to adjust the animation
using the facial rig. This is because named
phonemes are not part of the main blend
shape set structure used by the rig.
