Evaluating a new clinical palatometry system

Abstract

EPG (Electropalatography) is a visual feedback device designed for clinical and research applications centered on articulation in terms of tongue-to-hard palate contact. EPG has been shown to be effective for a range of speech sound disorders. Several EPG systems have been marketed. One factor that has limited access to EPG treatment, especially in a clinical setting, is the cost of manufacturing the pseudopalates. A new EPG system from Logometrix utilizes a glued on strip of electrodes rather than individually placed electrodes, significantly reducing production expense. Clinical use of the new EPG system is reviewed for 13 clients with varying speech sound disorders, for whom EPG was beneficial in phonetic treatment. Two children were unable to tolerate the pseudopalates, suggesting that practice palates without electrodes be utilized.
