Communication Sciences and Disorders 323

COSD 323: Speech Science

Credit Hours: (4) Three hours lecture; two hours laboratory


Introduction to the theories and models of speech production and perception, acoustic and physiological measures of speech and the role breakdowns in the normal speech production process have on various speech disorders.


Detailed Description of Course

The following topics will be covered in this course:

1. Basics of acoustic phonetics

2. Theories and models of speech production and perception

3. Acoustic and physiologic characteristics of speech production

4. Acoustic and physiologic measurements of speech

5. Disorders of speech production, to include those with neurological component (e.g. aphasia)


Detailed Description of Conduct of Course

Instructional activities may include in-class lectures, demonstrations, case studies, group activities, and lab exercises.


Student Goals and Objectives of the Course

Upon completion of this course, students will be able:

1. To define basic acoustical concepts.

2. To critically evaluate theories and models of speech production and perception.

3. To discuss the process of respiration and how it relates to speech production.

4. To examine phonetics from physiological, acoustical, and perceptual points of view.

5. To understand basic principles of resonance as it pertains to vocal tract resonance.

6. To understand the phonological process as it relates to phonological processing deficiencies.

7. To describe acoustic measures of speech in both the temporal and frequency domains.

8. To explain the involvement of neurology in speech production and speech perception.

9. To explain how applications of speech measures are considered as they apply to the diagnosis and management of disorders in speech production.


Assessment Measures

Assessment measures may include written homework assignments, in-class quizzes and exams, two spectrogram analysis labs (individual or group), and a comprehensive final exam.
