Martin J. Ball [+]
Until recently he was Professor of Clinical Linguistics and Phonetics at Linköping University, Sweden, having formerly held the position of Hawthorne-BoRSF Endowed Professor in the Department of Communicative Disorders, at the University of Louisiana at Lafayette. He received his bachelor’s degree with honours in Linguistics and English from the University of Wales (Bangor); his Master’s degree in phonetics and linguistics from the University of Essex; his Ph.D. from the University of Wales (Cardiff), and a DLitt degree from Bangor University.
Dr Ball has authored and edited over 35 books, 50 contributions to collections and 100 refereed articles in academic journals. He has also presented at conferences around the world. He is co-editor of the journal Clinical Linguistics and Phonetics (Taylor & Francis); and of the book series Studies in Phonetics and Phonology (Equinox), Communication Disorders across Languages (Multilingual Matters), and Language and Speech Disorders (Psychology Press). His main research interests include sociolinguistics, clinical phonetics and phonology, and the linguistics of Welsh. He has been President of the International Clinical Phonetics and Linguistics Association; he is an honorary Fellow of the UK Royal College of Speech and Language Therapists, and a Fellow of the Learned Society of Wales.

Many acquired neurogenic disorders have implications for accurate speech production. Some of these affect motor planning and motor execution (see Code and Ball, 1988), others have an impact on higher levels of speech organization. Speech problems associated with various types of aphasia have been the focus of sonority-based analyses for some time. Studies have included, for example, Christman’s work on sonority and neologistic jargon (1992a, b), and Code and Ball’s study of recurrent utterances (1994). In this chapter, we examine a range of data from aphasia and aphasia-like disorders. These include lexical and nonlexical recurrent utterances (or speech automatisms) in English, German and Chinese; patterns of gradual speech loss in progressive speech deterioration, and two cases of what Alajouanine (1956) and Perecman and Brown’s (1985) would term undifferentiated or phonemic jargon, respectively. For all these cases we described where sonority does, and does not, seem to explain the data, and speculate on whether sonority is hard-wired into the brain.
