Electropalatography in Phonetic Research and in Speech Training

Electropalatography (EPG) is an instrumental technique which displays and records spatio-temporal details of tongue contacts with the hard palate during continuous speech. It has been useful in experimental phonetic research, particularly in identifying lingual co-articulatory effects in different languages, and in describing the precise articulatory characteristics of complex lingual fricative sounds such as /s/. In speech pathology also, the technique has had important clinical applications. For example, as a remedial tool, it can provide an immediate, real-time display of palatal contacts which can be used to modify abnormal articulatory gestures associated with certain types of speech disorders. A similar application yet to be fully explored is in pronunciation teaching. This paper describes a pilot experiment in which two Japanese learners of English are taught to produce an acceptable /r/,/l/ contrast with the aid of EPG.
