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.
MeasureTransferFunction: A free and open-source PC software for the measurement of acoustic transfer functions using sine sweeps.
The Dresden Vocal Tract Dataset that contains geometric (e.g., MRI and 3D-printable models) and (aero)acoustic data of the vocal tract of 22 German speech sounds, each from one male and one female speaker.
Background information about articulatory speech synthesis.
We hope that this website, software and data 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.
