Opti-Speech is an interactive system that integrates tongue, lip, and jaw motion capture from 3D Electromagnetic Articulography (EMA) systems to animate a realistic 3D avatar. Users get real-time visual feedback of their tongue and jaw movements during speech therapy, which helps both them and the speech therapist to guide correct tongue positioning for speech sounds.
Tongue movements can be guided with customizable shape targets that are derived from normal speaker datasets or from users' own best movements.
Development of the Opti-Speech System is supported by the Small-Business Innovation Research (SBIR) grant 2R44DC013467
from the National Institute on Deafness and Other Communication Disorders.
