  A simplified model of articulatory synthesis involving four stages is
presented. The planning of articulatory gestures is based on syllable graphs
with arcs and nodes that are implemented in a complex representation. This was
first motivated by a reduction in the many-to-one relationship between
articulatory parameters and formant space. This allows for consistent
trajectory planning and computation of articulation dynamics with coordination
and selection operators. The flow of articulatory parameters is derived from
these graphs with four equations. Many assertions of Articulatory Phonology
have been abandoned. This framework is adapted to synthesis using VLAM (a
Maeda's model) and simulations are performed with syllables including main
vowels and the plosives /b,d,g/ only. The model is able to describe
consonant-vowel coarticulation, articulation of consonant clusters, and verbal
transformations are seen as transitions of the syllable graph structure.
