Welcome to ArtiSynth
A 3D Biomechanical Modeling Toolkit for
Physical Simulation of Anatomical Structures

ArtiSynth is a 3D biomechanical simulation platform directed toward modelling the vocal tract and upper airway. It provides an open-source, cross-platform environment in which researchers can create and interconnect various kinds of dynamic and parametric models to form a complete integrated biomechanical system that is capable of articulatory speech synthesis. An interactive graphical timeline runs the simulation and allows the temporal arrangement of input/output channels to control or observe properties of the model's components. Library support is available for particle-spring and rigid body systems, finite element models, and spline-based curves and surfaces. To date, these have been used to create a dynamic muscle-based model of the jaw, a deformable tongue model, a deformable airway, and a non-linear acoustics model, which have been connected together to form a complete vocal tract that produces speech and is drivable both by data and by dynamics.

Primary development of ArtiSynth is being undertaken in the Electrical and Computer Engineering and Computer Science Departments of the University of British Columbia, Vancouver, Canada.

Researchers from around the world continue to add new models and modeling techniques to ArtiSynth.
