Various research areas

Ultrasound

Ultra high-frequency sound waves are used to create movies of planar tongue motion. The 2D planar motion can be reconstructed into 3D surface motion.Click to download a Guide to Analyzing Tongue Motion from Ultrasound Images.Our applications of this technology include:

Visualizes and compares multiple contours using SURFACES.

Magnetic Resonance Imaging (MRI)

Vocal tract images are made in multiple planes during sustained speech sounds. Tagged Cine-MRI (tMRI) allows tracking of tissue points in oral structures.
