Updated fully in its Second Edition, Articulatory and Phonological Impairments provides students with a clinical framework that encompasses basic terms and concepts, phonetic transcription, and theoretical perspectives extensively applied to clinical examples. This text demonstrates a systematic transition from a knowledge base in clinical practice to the diagnosis and treatment of individuals with articulatory/phonological disorders. While this text offers a thorough discussion of phonetic principles (also known as the traditional or motor approach) applied to the diagnosis and treatment of motor-based disorders, emphasis is placed on phonemic approaches. Contemporary issues such as phonological assessment, various phonemic-based therapies, and newer nonlinear/multi-linear phonologies and their role in the assessment and intervention process are treated in detail.
