"In this paper we describe a parameterisation of lip movements
which maintains the dynamic structure inherent in the task of
producing speech sounds. A stereo capture system is used to
reconstruct 3D models of a speaker producing sentences from
the TIMIT corpus. This data is mapped into a space which
maintains the relationships between samples and their temporal
derivatives. By incorporating dynamic information within
the parameterisation of lip movements we can model the cyclical
structure, as well as the causal nature of speech movements
as described by an underlying visual speech manifold. It is believed
that such a structure will be appropriate to various areas
of speech modeling, in particular the synthesis of speech lip
movements."
