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 several theoretical perspectives and extensively applies them to clinical examples.
This text demonstrates to students 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. Case studies are used to demonstrate a step-by-step process of multiple assessment strategies focusing on phonetic and phonemic analyses and clinical case study exercises provided throughout the text demonstrate different types of phonemic analyses and how they lead to therapeutic decision-making. Contemporary issues such as features of a 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.
New to this Edition:
- Extensive revision of chapter 3 to reflect the newer transcription systems offered by the International Phonetic Alphabet (IPA) and the Extensions to the IPA (extIPA).
- In Chapter 4, the section on multilinear approaches has been extended to include optimality theory and its clinical applications.
- Updates throughout of new information discovered since the First Edition.
