Advances in EPG for treatment and research: an illustrative case study

By James M Scobbie, Sara Wood and Alan A Wrench


Electropalatography (EPG), a technique which reveals tongue-palate contact\ud patterns over time, is a highly effective tool for speech research. We report here\ud on recent developments by Articulate Instruments Ltd. These include hardware\ud for Windows-based computers, backwardly compatible (with Reading EPG3)\ud software systems for clinical intervention and laboratory-based analysis for EPG\ud and acoustic data, and an enhanced clinical interface with client and file\ud management tools. We focus here on a single case study of a child aged 10¡\ud years who had been diagnosed with an intractable speech disorder possibly\ud resulting ultimately from a complete cleft of hard and soft palate. We illustrate\ud how assessment, diagnosis and treatment of the intractable speech disorder are\ud undertaken using this new generation of instrumental phonetic support. We also\ud look forward to future developments in articulatory phonetics that will link EPG\ud with ultrasound for research and clinical communities.\ud Keywords: Electropalatography, ultrasound, speech disorders, perceptual analysi
