An EPG therapy protocol for remediation and assessment of articulation disorders

Alan Wrench, Fiona Gibbon, Alison M. McNeill, Sara Wood

This paper describes technical and methodological advances in the development of a procedure for measuring changes in accuracy and stability of linguapalatal (tongue-palate) contact patterns during a course of visual feedback therapy using electropalatography (EPG). The procedure is exemplified by a case in which therapy was aimed at resolving a pattern of velar fronting whereby phonetic targets /k, g, 6/ had abnormal alveolar placement [t, d, n]. The EPG remediation and assessment procedure can be implemented using recording, feedback and analysis software designed for the purpose.
