    Advances in EPG for treatment and research: an illustrative case study
    (Taylor & Francis, 2004) Scobbie, James M.; Wood, Sara; Wrench, Alan A.
    Electropalatography (EPG), a technique which reveals tongue-palate contact patterns over time, is a highly effective tool for speech research. We report here on recent developments by Articulate Instruments Ltd. These include hardware for Windows-based computers, backwardly compatible (with Reading EPG3) software systems for clinical intervention and laboratory-based analysis for EPG and acoustic data, and an enhanced clinical interface with client and file management tools. We focus here on a single case study of a child aged 10 years who had been diagnosed with an intractable speech disorder possibly resulting ultimately from a complete cleft of hard and soft palate. We illustrate how assessment, diagnosis and treatment of the intractable speech disorder are undertaken using this new generation of instrumental phonetic support. We also look forward to future developments in articulatory phonetics that will link EPG with ultrasound for research and clinical communities.

    Advances in EPG palate design.
    (Taylor & Francis, 2007) Wrench, Alan A.
    Electropalatography (EPG) is a highly effective tool for speech research and for the diagnosis and treatment of a range of speech disorders. The technique requires an EPG palate to be custom made for each user. The manufacture of the palate is both costly and time consuming and inhibits wider uptake of the technique. This paper undertakes a thorough reexamination of all aspects of EPG palate design including criteria for selecting the number and location of contacts, materials properties, costs and safety issues. Palate design over the last 30 years is reviewed and a new design (the Articulate palate) is proposed based on the findings, which minimizes cost while maximizing comfort, safety, convenience, reliability and accuracy.
