Innovations in biofeedback technology provide the unique opportunity for dynamic and visual intervention of articulatory disorders, especially in cases where the target sound is hard to describe or see. One of the primary modes of this visual biofeedback is electropalatography (EPG), which provides information about tongue-hard palate contact points through sensors integrated in a custom-made artificial palate moulded to fit against a speaker's hard palate. EPG intervention has been previously investigated in its efficacy in remediating persistent misarticulations and found to have short-term benefits for children and adolescents who are profoundly deaf or hard of hearing (Bacsfalvi, Bernhardt, and Gick, 2003; Bacsfalvi, Bernhardt, and …show more content…

Established long term benefit would be strong support in adopting EPG intervention into mainstream therapy methodology. In addition, there is the barrier of cost. Since, the intervention equipment itself is not easily obtained by speech pathologists, a strong evidence base with more large scale randomized studies is necessary to justify the cost of this intervention method. Currently, many of the studies examining this method of intervention are comprised of a small case series or a single case study due to the wide variation in articulatory errors assessed by this method of therapy. It is generally accepted that it is difficult to stereotype the articulatory patterns of deaf and hard of hearing individuals, due to the wide range of variability in segmental production between and within speakers of normal hearing (Vuckovich, M. 2006). For this reason, this intervention method has largely been evaluated via case series. However, adjusting targets to examine a more comprehensive battery of sounds would allow for a larger sample size and randomized design. It has yet to be investigated if individuals who are deaf or hard of hearing need continued practice with electropalatography technology in order to establish long term generalization of articulatory patterns. It would be crucial to determine production improvements of treatment targets, generalization targets, as well
