Welcome to VocalTractLab
On this website you find:
VocalTractLab: An articulatory speech synthesizer and tool to visualize and explore the mechanisms
of speech production with regard to articulation, acoustics, and control.
Image3D: A tool for the exploration of volumetric magnetic resonance images and tracing of contours in these images.
GlottalImageExplorer: A free and open-source PC software for the segmentation of the glottis in endoscopic high-speed films of the larynx.
TargetOptimizer: A free and open-source PC software for the estimation of pitch targets from the f0-contour of spoken utterances.
Background information about articulatory speech synthesis and the models and methods implemented in VocalTractLab.
We hope that this website and software will facilitate the understanding of the human vocal system and the principles of speech production.
VocalTractLab was developed as a research tool by Peter Birkholz
and is continually extended due to ongoing research.
