For forty years, this textbook has been the gold-standard resource for providing speech-language pathologists with a strong foundation of knowledge on speech sound disorders. Previously published as Articulation and Phonological Disorders, this core text is now in its ninth edition, fully updated and expanded to meet the needs of todays clinicians as they work with children of all ages.

A cornerstone of every SLPs professional preparation, the new edition of this book offers the most up-to-date, comprehensive coverage of contemporary clinical literature and the best available treatments for speech sound disorders. With a focus on evidence-based practice, the expert authors and contributors present essential information and guidelines on a broad range of topics, from the basics of typical speech production to recommended practices for assessment and intervention. Updates include new and expanded chapters on timely topics, new instructor materials and student-friendly features, and helpful guidance for clinicians serving an increasingly diverse population.

With this authoritative synthesis of research and practice, the next generation of SLPs will have the broad and deep knowledge they need to understand speech sound disorders and provide children with the best possible supports and interventions.
