A muscle-driven model of human lower face was established. Three pairs of fac ial mimic muscles (ZM-Zygomaticus Major, LLS-Levator Labii Superioris, LAO-Levator Anguli Oris), subcutaneous soft tissues, skin and skull were reconstructed based on segmentation of subject-specific MRI data. FE simulation were performed to reproduc e designed facial mimic positions (e.g. pronunciation of sound /o/ ), with comparison to experimental measurements. Muscle was modeled as a transversely-isotropic hyperelastic material with autonomous contraction.
