Welcome to VocalTractLab

This web site features:

VocalTractLab: An interactive multimedia application for the simulation and study of speech production. This software contains a complete articulatory speech synthesizer!
Image3D: A tool for the exploration of volumetric magnetic resonance images and the tracing of outlines in these images.
Background information about articulatory speech synthesis and the models and methods implemented in VocalTractLab.

We hope that this web site and the software made available here will help interested people to improve their understanding of the human vocal system and the principles of speech production.
