Critical Review: Electropalatography and the productive speech intelligibility of children and adolescents with hearing impairments

This critical review examines the effects of electropalatography (EPG) on the productive speech intelligibility of children and adolescents with severe to profound hearing impairments. Study designs include: case study, case series and comparison study. Overall, research supports the use of EPG technology with this population in developing more typical tongue-palate contact patterns and improving speech intelligibility. However, the evidence base for this field of research is limited and the studies reviewed demonstrate methodological weaknesses. Recommendations for future research and clinical practice are provided.
