ABSTRACT

Clinical phonetics has experienced substantial development over the past few decades, benefitting from innovations in medicine, engineering, linguistics, and speech science. Phonetic data from disordered populations are of key interest to researchers, as this information may provide a window into the neural and functional organization of speech and language. In addition, cognitive/linguistic perspectives may help clinicians better understand, describe, and treat speech and language disorders. This chapter presents a brief history of the field and addresses some of the basic principles that emerge by exploring how the audiovisual nature of speech affects both healthy individuals and those with speech and language disorders. This includes discussion of how recent methods of providing visual articulatory feedback may be useful in working with healthy participants (e.g., in L2 pronunciation training) as well as with clinical populations.
