An infrared reflective marker tracking system is introduced in this paper. This system is designed to measure facial muscle movement for communication disorder research. The extent and timing of jaw opening and lip spreading are monitored while subjects are performing a variety of speech production tasks with different speech or voice facilitating strategies. This facial tracking device is used in combination with acoustic and electroglottographic recordings to allow for an investigation of the oral-laryngeal coordination. A calibrator with known geometry properties is used to compensate for errors resulted from a subject’s head movement and convert pixel distance to real distance in millimeters.
