Speech Science as the Foundation for Voice and Motor Speech Disorders

Abstract

Physiological concepts can be effectively taught in speech science. These will serve as the foundation for understanding the physiological changes associated with neurogenic and voice disorders. In this tutorial, relevant concepts are highlighted across the respiratory, phonatory, velopharyngeal, and articulatory systems. Student activities and illustrative videos are presented. The culminating activity is based on a speech sample of an individual with moderate flaccid–spastic dysarthria. Students relate the physiological changes associated with dysarthria to the acoustic outcomes. Although traditionally speech science focuses on acoustics, this tutorial provides guidance on shaping the class to highlight the physiology underlying the acoustics. In this manner, students more easily see the clinical relevance.
