title: A new head-mounted lip-jaw movement transduction system for the study of motor speech disorders.
abstract: A new head-mounted lip and jaw transduction system is described, which features (a) an ultra-low mass tubular aluminum headmount mainframe with a unique coupling apparatus, (b) a low mass transducer unit, (c) nonrestraint of the head, and (d) a transduction artifact of .1 mm or less under most recording conditions. The importance of observing labial and mandibular movements in addition to electromyographic and aerodynamic signals is emphasized by reference to actual recordings of speech from subjects with neuromotor disorders.
