A video-based system for recording speech movements in three dimensions.

Research output: Contribution to journalArticle


An examination of speech articulator movement used a video-based system for tracking & recording movement in three dimensions - the MacReflex(R). The system is noninvasive with no hazardous radiation or electromagnetic field, & no wires to impede movement. The facility is currently used at the Depts of Clinical Neurophysiology & Clinical Oral Physiology, U of Umea, to study strategies for motor control of precise movement in the hand, neck, & mandible, & in various neurological disabilities.
