Being intelligible to a listener means getting your message across and improving speech intelligibility is one of the most common goals for clients working with a speech-language pathologist (SLP). Improving Speech Intelligibility in Adults: Clinical Application of Evidence-Based Strategies is a professional resource for practicing SLPs working with adults with communication disorders, such as dysarthria, acquired apraxia of speech, and voice disorders.

 

This book incorporates current research findings to support the use of evidence-based strategies in clinical situations. While other books may focus on “drilling” and “practicing” a list of words, sentences, and topics to use with a client to change their behaviors, Improving Speech Intelligibility in Adults uniquely focuses on the speaker and the listener in tandem. The author takes a noteworthy approach in how the listener can change behaviors to assist with understanding. The text presents a comprehensive approach to improving speech intelligibility by including ways to enhance the communication environment during in-person or teletherapy exchanges to enhance understanding between speaker and listener.

Connie K. Porcaro

Connie Porcaro, PhD, CCC-SLP is an Associate Professor in the Department of Communication Sciences and Disorders at Florida Atlantic University (FAU), where she instructs courses covering Voice, Speech, and Swallowing disorders in adults, and lectures annually for future physicians at the FAU Medical School on the topics of adult neurogenic speech and language disorders. Dr. Porcaro is certified by the American Speech-Language-Hearing Association and has worked as a speech-language pathologist for more than 25 years with clients of all ages. Her main area of research is focused on intelligibility in patients with speech and voice disorders and how speakers and listeners can have improved communication. . Dr. Porcaro is a frequent presenter at the Annual Convention of the American Speech-Language and Hearing Association and state association conventions as an invited speaker on the topic of intelligibility. She has received grant funding from the FAU Healthy Aging Research Initiative to investigate voice and swallowing changes in healthy elderly individuals, and she has received grant funding from the Parkinson Voice Project to facilitate training for graduate students who provide free-of-cost speech therapy for individuals with Parkinson’s disease.
