This paper presents an articulator movement model that was devised by specifying the motor task for each phoneme in terms of vocal tract parameters representing lip protrusion, opening height, and tongue shape. Articulator movements were generated to form the vocal tract into specific shapes while minimizing the energy criterion that resolves the kinematic redundancies caused by the coordinated structure of speech organs and by the requirement to interpolate consecutive motor tasks. This paper also examines the task-independent energy criterion that predicts movements for different phoneme strings with different utterance styles. Simulation results were compared with actual movements to quantitatively show the capability of the model.
