== Description ==
{{unreferenced section|date=March 2024}}
The central component of the program is the face graph. It combines bone poses and morph targets to a single target which is driven by animation curves. These are created by a [speech recognition](/source/speech_recognition) system but can also be manually edited. The facial animation is then outputted to the game engine either as [bone transformation](/source/Skeletal_animation) or [morph target](/source/Morph_target_animation) frame by frame.

To create a realistic animation curve, the program recognizes 42 [phonemes](/source/phonemes) and tries to take co-articulation rules into account. It also tries to create head movement, blinks, and eyebrow raises from emphasis points in the audio file.
