  We present an interface involving four degrees-of-freedom (DOF) mechanical
control of a two dimensional, mid-sagittal tongue through a biomechanical
toolkit called ArtiSynth and a sound synthesis engine called JASS towards
articulatory sound synthesis. As a demonstration of the project, the user will
learn to produce a range of JASS vocal sounds, by varying the shape and
position of the ArtiSynth tongue in 2D space through a set of four force-based
sensors. In other words, the user will be able to physically play around with
these four sensors, thereby virtually controlling the magnitude of four
selected muscle excitations of the tongue to vary articulatory structure. This
variation is computed in terms of Area Functions in ArtiSynth environment and
communicated to the JASS based audio-synthesizer coupled with two-mass glottal
excitation model to complete this end-to-end gesture-to-sound mapping.
