Articulation Characteristics of Severely and Profoundly Deaf Children and Approaches to Therapy: A Review of the Electropalatography Literature

Abstract

This article provides a concise review of (i) the segmental articulation errors produced by severely and profoundly deaf children and (ii) the approaches to therapy carried out to remediate these errors. In both cases, evidence is gathered from studies using electropalatography (EPG), an instrumental technique which provides a direct articulatory display of the timing and location of contact between the tongue and the hard palate during speech. Attention is paid to what is known about the generalisation and maintenance of improvements in speech production following EPG visual feedback therapy.
