The International Clinical Phonetics and Linguistics Association (ICPLA) is a non-profit-making international scholarly association devoted to the study of phonetics and linguistics in relation to speech disorders and language disorders.
Specifically its mission is to:
It was founded in 1991 at the Symposium on Advances in Clinical Phonetics held at the Cardiff Institute of Higher Education, Wales.
The official journal of the Association is Clinical Linguistics and Phonetics published since 1987 by Taylor and Francis. It has appeared on a monthly basis since 2007. [1] The original editors were: Martin J. Ball, Raymond D. Kent, Nicole Müller, and Thomas W. Powell. Current editors are Vesna Stoyanovik and Tim Bressman.

The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩, and the equivalent X-SAMPA symbol is K\
.
The close central unrounded vowel, or high central unrounded vowel, is a type of vowel sound used in some languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɨ⟩, namely the lower-case letter i with a horizontal bar. Both the symbol and the sound are commonly referred to as barred i.
David Crystal, is a British linguist who works on the linguistics of English language.
Peter Nielsen Ladefoged was a British linguist and phonetician. He was Professor of Phonetics at University of California, Los Angeles (UCLA), where he taught from 1962 to 1991. His book A Course in Phonetics is a common introductory text in phonetics, and The Sounds of the World's Languages is widely regarded as a standard phonetics reference. Ladefoged also wrote several books on the phonetics of African languages. Prior to UCLA, he was a lecturer at the universities of Edinburgh, Scotland and Ibadan, Nigeria (1959–60).
The Extensions to the International Phonetic Alphabet for Disordered Speech, commonly abbreviated extIPA, are a set of letters and diacritics devised by the International Clinical Phonetics and Linguistics Association to augment the International Phonetic Alphabet for the phonetic transcription of disordered speech. Some of the symbols are used for transcribing features of normal speech in IPA transcription, and are accepted as such by the International Phonetic Association.
Clinical linguistics is a sub-discipline of applied linguistics involved in the description, analysis, and treatment of language disabilities, especially the application of linguistic theory to the field of Speech-Language Pathology. The study of the linguistic aspect of communication disorders is of relevance to a broader understanding of language and linguistic theory.
Martin J. Ball FRCSLT FRSA FLSW is Honorary Professor in Linguistics at Bangor University in Wales. Until August 2017 he was Professor of Speech-Language Pathology at Linköping University in Sweden. He holds joint Irish-UK-US citizenship. As of June 2019 he lives in Cork, Ireland.
The phonology of Welsh is characterised by a number of sounds that do not occur in English and are rare in European languages, such as the voiceless alveolar lateral fricative and several voiceless sonorants, some of which result from consonant mutation. Stress usually falls on the penultimate syllable in polysyllabic words, while the word-final unstressed syllable receives a higher pitch than the stressed syllable.
John Cunnison "Ian" Catford was a Scottish linguist and phonetician of worldwide renown.
Antônio Roberto Monteiro Simões is a Brazilian-born linguist interested in the phonetics and phonology of the Romance languages. Simões is an associate professor of Spanish and Portuguese linguistics at the University of Kansas, in Lawrence, USA, where he teaches Hispanic linguistics. He has authored books, textbooks and articles contrasting the Portuguese and Spanish languages. Simões is currently conducting research work on speech models and foreign language learning models, especially in relation to phonetics and phonology. Simões work on modeling is a continuation of his Ph.D. thesis; an adaptation of the late Dennis Klatt's 1976 pioneering model to predict duration in connected speech.
A velopharyngeal fricative, also known as a posterior nasal fricative, is a sound produced by some children with speech disorders, including some with a cleft palate, as a substitute for sibilants, which cannot be produced with a cleft palate. It results from "the approximation but inadequate closure of the upper border of the velum and the posterior pharyngeal wall." To produce a velopharyngeal fricative, the soft palate approaches the pharyngeal wall and narrows the velopharyngeal port, such that the restricted port creates fricative turbulence in air forced through it into the nasal cavity. The articulation may be aided by a posterior positioning of the tongue and may involve velar flutter.
Voice Quality Symbols (VoQS) are a set of phonetic symbols used to transcribe disordered speech for what in speech pathology is known as "voice quality". This phrase is usually synonymous with phonation in phonetics, but in speech pathology encompasses secondary articulation as well.
Meena Upadhyaya OBE, FRCPath, FLSW is an Indian-born Welsh medical geneticist and an honorary distinguished professor at Cardiff University. Her research has focused on the genes that cause various genetic disorders, in particular neurofibromatosis type I and facioscapulohumeral muscular dystrophy.
Nicole Müller is Professor of Speech and Hearing Sciences at University College Cork in Ireland, with specialisms in aphasia and dementia, having held the position of Professor of Speech-Language Pathology at Linköping University in Sweden until the end of January 2017.
Peter John Roach is a British retired phonetician. He taught at the Universities of Leeds and Reading, and is best known for his work on the pronunciation of British English.
Jane Setter is a British phonetician. She teaches at the University of Reading, where she is Professor of Phonetics. She is best known for work on the pronunciation of British and Hong Kong English, and on speech prosody in atypical populations.
Ultrasound tongue imaging (UTI) has been used for speech production and linguistics research since it came into regular clinical use in the 1960s and 1970s.
