From: Lip-Synching Using Speaker-Specific Articulation, Shape and Appearance Models
A zoomed portion of Figure 7 evidencing that PHMM (red) captures the original carryover movements (dark blue) of the open consonant [sh] into the [ua] vowel.We plot here the behavior of the lower and upper lip opening. PHMM predicts a protrusion of the lips into half of the duration of the [ua] allophone while both HMM-based (light blue) and concatenation-based (black) trajectory formation systems predict a quite earlier retraction at acoustic onset. In the original stimuli the protrusion is sustained till the end of the word "ensures".
