A VIDEO-BASED SYSTEM FOR RECORDING SPEECH MOVEMENTS IN 3 DIMENSIONS

This paper reports a study of speech articulator movement using a vide o-based system for tracking and recording movement in three dimensions , the MacReflex(R). The system is non-invasive, there is no hazardous radiation or electromagnetic field, and there are no wires that might impede movement by the subject. The facility is installed at the facul ty of odontology (Departments of Clinical Neurophysiology and Clinical Oral Physiology) at the University of Umea, where it is currently bei ng used to study strategies for motor control of precise movement in t he hand, in the neck and mandible, and in various neurological disabil ities.
