In this work are papers presented at the Fifth Annual Meeting of the International Clinical Phonetics and Linguistics Association (ICPLA). They cover a range of topics, from infant babbling to language in dementia, from pragmatic disabilities to cleft palate articulation, and from slow potentials to nasalance measures. Some of the papers contribute to fundamental issues of speech and language disorders, others to clinical issues such as assessment and treatment. The book also covers a variety of research questions, patient groups, syndrome taxonomies, experimental paradigms and measurement techniques. The overall aim is to increase the understanding of communication disorders, and to improve the methodologies for diagnosing and treating them.
