This course considers the anatomic, physiologic, acoustic, and perceptual aspects of normal voice and selected voice problems across the lifespan. A hypothesis-driven context and patient-centered framework is used to develop protocols for prevention of voice problems, identification of risk factors, and promotion of efficient phonation. We will discuss the impact of multicultural and psychosocial factors on voice. Participation in labs links motor learning theory to manner of phonation and facilitates development of goals and identification of appropriate procedures.
