This paper presents an investigation of the visual variation on the bilabial plosive consonant /p/ in three coarticulation contexts. The aim is to provide detailed ensemble analysis to assist coarticulation modelling in visual speech synthesis. The underlying dynamics of labeled visual speech units, represented as lip shape, from symmetric VCV utterances, is investigated. Variation in lip dynamics is quantitatively and qualitatively analyzed. This analysis shows that there are statistically significant differences in both the lip shape and trajectory during coarticulation.
