Vocal tract images are made in multiple planes during sustained speech sounds. Tagged Cine-MRI (tMRI) allows tracking of tissue points in oral structures.
Ultra high-frequency sound waves are used to create movies of planar tongue motion.
Acrylic palates, custom made to fit each subject's palate, record tongue-palate contact in real time.
Modeling the interdigitated tongue muscles tests the many muscle combinations used to produce speech.
The tongue can be segmented into regions that produce a speech gesture using coordinated muscle activation strategies.
Tongue surface deformation creates a transverse waveform that propels the bolus from the oral cavity (front) into the pharynx (back).
We study speech adaptation to glossectomy surgery, which removes a malignant tumor from the tongue. A ‘flap’ and may be used to replace the tissue.
Vocal tract airway sections are calculated from reconstructed 3D super-resolution volumes, and used to generate speech spectra.
