UltrasoundUltra 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:
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.
Electropalatography (EPG)Acrylic palates, custom made to fit each subject's palate, record tongue-palate contact in real time.
