About The Book

Preclinical Speech Science: Anatomy, Physiology, Acoustics, and Perception, Third Edition is a high-quality text for undergraduate and graduate courses in speech and hearing science. Written in a user-friendly style by distinguished scientists/clinicians who have taught the course to thousands of students at premier academic programs, it is the text of choice for instructors and students. Additionally, it is applicable to a broad range of courses that cover the anatomy and physiology of speech production, speech acoustics, and swallowing as well as those that cover the hearing mechanism, psychoacoustics, and speech perception.

The material in this book is designed to help future speech-language pathologists and audiologists to understand the science that underpins their work and provide a framework for the evaluation and management of their future clients. It provides all the information students need to be fully ready for their clinical practicum training.

Thomas J. Hixon, PhD, (1940-2009), received his PhD from the University of Iowa and did postdoctoral work in physiology at Harvard University. He was Professor Emeritus of Speech, Language, and Hearing Sciences and Dean Emeritus of the Graduate College at the University of Arizona and had been Head of the Department of Speech, Language, and Hearing Sciences, Director of the National Center for Neurogenic Communication Disorders, Director of Graduate Interdisciplinary Programs, Director of the Movement Neuroscience Program, Research Integrity Officer, and Associate Vice President for Research at the same institution. Dr. Hixon was a Fellow of the American Speech-Language-Hearing Association and was awarded Honors of the Association, the Council of Editor’s Award, two Journal Editor’s Awards from the Association for the outstanding article of the year, and a Career Teaching Award from the University of Arizona. Dr. Hixon served as Editor of the Journal of Speech and Hearing Research, Speech Section Editor of the Journal of Speech, Language, and Hearing Research, and an editorial reviewer and/or Associate Editor to over a dozen other speech and voice journals. His research interests centered on normal and abnormal speech production and the biomechanics of singing.

Gary Weismer, PhD, is Oros-Bascom Professor Emeritus in the Department of Communication Sciences & Disorders, University of Wisconsin-Madison. He received his bachelor’s and master’s degrees from the Pennsylvania State University and his doctorate from University of Wisconsin-Madison in 1975. Dr. Weismer’s research publications concern speech production in healthy talkers, as well as speech production and speech intelligibility in persons with motor speech disorders. Dr. Weismer served twice as Associate Editor for the Journal of Speech, Language, and Hearing Research (formerly the Journal of Speech and Hearing Research), as Associate Editor at Folia Phoniatrica et Logopaedica (FPL) from 2004 to 2011, and as Editor-in-Chief at FPL from 2011 to 2016. During his 35 years at University of Wisconsin-Madison, Dr. Weismer won several teaching awards, including for mentoring efforts in the University of Wisconsin-Madison Honors program. Dr. Weismer mentored 16 doctoral students during his career, many of whom are currently scientific leaders and university administrators. He is a past member of the Executive Board of the International Association of Logopedics and Phoniatrics IALP), an Honored Member of IALP, a Fellow of the Acoustical Society of America, and past chair of his department. He has edited, authored, and coauthored five textbooks.

Jeannette D. Hoit, PhD, CCC-SLP is Professor in the Department of Speech, Language, and Hearing Sciences and Director of Postdoctoral Affairs at the University of Arizona and a speech-language pathologist. Dr. Hoit received her BA in Anthropology from the University of California at Los Angeles, her MA in Communicative Disorders from San Diego State University, and her PhD in Speech and Hearing Sciences from the University of Arizona, and she pursued postdoctoral study in the Harvard School of Public Health Respiratory Biology Program and the Massachusetts Institute of Technology Speech Research Laboratory. Dr. Hoit’s research focuses on speech physiology, with an emphasis on normal aging and development, neuromotor speech disorders, and respiratory function and dysfunction. Dr. Hoit is a past editor of the American Journal of Speech-Language Pathology, a fellow of the American Speech-Language-Hearing Association, and past president of the American Association of Phonetic Sciences. She has received a Distinguished Alumnus Award from San Diego State University and several teaching and mentoring awards from the University of Arizona.
