Visual coarticulation effects in syllable environment

Hans-H. Bothe, Frauke Rieger, Robert Tackmann

This paper describes a method of analyzing visual articulation movements and determining coarticulation effects with respect to syllables. A modified DTW process (Dynamic Time Warping) has been used as a measure of local similarity and applied on the visual correlates of several frequent German syllables. These investigations lead to speaker dependent sets of coarticulation data. They are suggested to be used for a model-based computer-animation program showing an artificial speaker on the screen.
