Measuring Voice, Speech, and Swallowing in the Clinic and Laboratory provides a definitive reference and text for methods of measurement of voice, speech, and swallowing functioning and disorders. It was developed for measurement courses in speech-language pathology graduate and doctoral programs and is also an essential reference for practitioners or anyone who needs to make quantitative assessments of the systems involved. The goal of this text is to provide basic information on the instruments and measures commonly used for assessing and treating persons with disorders of voice, speech, and swallowing for clinical practice, research studies, and conducting clinical trials. New developments in electrical and magnetic stimulation for noninvasive stimulation of nerves, muscles, and the brain are provided for augmenting treatment benefits for persons with voice, speech, and swallowing disorders. Other new techniques included are electromyography, articulography, transcranial magnetic stimulation, functional MRI, fNIRS, DTI, and transcranial direct current stimulation for treatment applications.

The text includes methods for recording and analyzing speech, acoustics, imaging and kinematics of vocal tract motion, air pressure, airflow, respiration, clinical evaluation of voice and swallowing disorders, and functional and structural neuroimaging. Many of the methods are applicable for use in clinical practice and clinical research.

Key Features:

  • More than 250 full-color images
  • Summary tables to guide selection of instruments and measures for various applications
  • Each chapter begins and ends with an overview and conclusion for review of content
  • Appendices of measurement standards

Clinical investigators and clinicians wanting to measure voice, speech, and swallowing functions for clinical documentation will benefit from this book, as will students and professors. Measuring Voice, Speech, and Swallowing in the Clinic and Laboratory pulls together the necessary information on methods of measurement from different disciplines and sources into one convenient resource. Information on measurement in the fields of voice, speech, and swallowing is now readily available for training doctoral students and guidance of clinicians incorporating instrumental assessment into their practice.


"When I first received the book, I was surprised to find that it is a spirally-bound book. When I opened the book and first read the content coverage and the preface by the authors, then I am convinced that this is a well thought-through decision as this book is meant to be a reference book which clinicians and researchers have to flip through the book every now and then. So, this binding type will withstand the constant use of the book. Of course, the typesetting, binding and printing of a book determine how to attract readers. But the usefulness of a book is no doubt determined most importantly by the content. If you expect that this book would teach you how to carry out meaningful measurements, yes, it would. If you expect that this to be the "recipe" book, then it is not. This book is written by 3 serious and renowned scholars who have spent their professional life time just by researching, practicing and teaching measurement in speech, voice and swallowing science. So, the information in the book is state-of the-art references. When I said it is not a recipe book, this can be seen how the 3 authors included the basic understanding of signals properties, electricity basics and measurement principles as the first 3 chapters of the book. This gives a very important ground work for the understanding of how to make measurement and how to interpret the measures. Such information is fundamental to understand instrumental measurement and students, clinicians and researchers will find these chapters very helpful for understanding why certain measurements have to be done in such a way and not the other ways. The remainder of the book covers the muscular systems involved in voice and swallowing, basic speech science measurements that include acoustic, aerodynamic, imaging of voice and swallowing functions, and contemporary techniques in neuroimaging and neuro-intervention. All the information covering these wide range of areas are contained in this 550+ pages book with extensive references cited. I have no doubt that this will become one of the classics for the professions in speech-language pathology, otolaryngology, and speech science."

Christy L. Ludlow

Christy L. Ludlow, PhD, began her career as a speech-language pathologist before moving into clinical and basic research on speech and voice at the National Institutes of Health, where she conducted research for 35 years. She was Chief the Laryngeal and Speech Section and became a Senior Investigator in the National Institute of Neurological Disorders and Stroke conducting both basic and clinical neurophysiological studies of normal and disordered voice, speech, and swallowing. She then moved to the Department of Communication Sciences and Disorders at James Madison University, where she led the PhD program and established the Voice and Swallowing Service, a joint collaboration between the university and the Sentara RMH Hospital.
