"The aim of the study is to learn the relationship between facial movements 
and the acoustics of speech sounds. We recorded A database of 3D video of 
the face, including markers, and corresponding synchronized audio of a 
single speaker. The database consists of 110 English sentences. These 
sentences were selected for strong expressive content in the fundamental 
emotions: Anger, Surprise, Sadness, Happiness, Fear and Disgust. 
Comparisons are made with the same sentences with neutral expression. 
Principal component analysis of the marker movements was performed to 
identify significant modes of variation. The results of this analysis show 
that there are various characteristic difference between visual features of 
emotional versus neutral speech. The findings of the current research 
provide a basis for generating realistic animations of emotional speech for 
applications such as computer games and films."
