要旨

We present a method for generating realistic speech-synchronized
facial animations using a physics-based approach and support for
coarticulation, i.e.\ the coloring of a speech segment by
surrounding segments. We have implemented several extensions to
the original coarticulation algorithm of Cohen and Massaro. The
enhancements include an optimization to improve performance as
well as special treatment of closure and release phase of
bilabial stops and other phonemes. Furthermore, for phonemes
that are shorter than the sampling intervals of the algorithm
and might therefore be missed, additional key frames are created
to ensure their impact onto the animation.
