    Electropalatographic therapy for children and young people with Down's syndrome
    (2009-12) Cleland, Joanne
    Articulation disorders in Down's syndrome (DS) are prevalent and often intractable. Individuals with DS generally prefer visual to auditory methods of learning and may therefore find it beneficial to be given a visual model during speech intervention, such as that provided by electropalatography (EPG). In this study, participants with Down's syndrome, aged 10:1 to 18:9, received 24 individualized therapy sessions using EPG. Simultaneous acoustic and EPG recordings were made pre- and post-intervention during 10 repetitions of a word list containing lingua-palatal consonants. Participants also completed the DEAP phonology sub-test at both time points. Post-treatment, all participants showed qualitative and quantifiable differences in EPG patterns and improvements in DEAP percentage consonants correct. EPG assessment and therapy appears a positive approach for identifying and improving articulatory patterns in children with DS. © 2009 Informa UK, Ltd

    An electropalatographic investigation of middorsum palatal stops in an adult with repaired cleft palate.
    (Allen Press Incorporated, 2001-03) Gibbon, Fiona; Crampin, Lisa
    Objective: Middorsum palatal stops are compensatory articulations that occur relatively frequently in cleft palate speech. This study used electropalatographic (EPG) and acoustic data to investigate /t/ and /k/ targets produced as middorsum palatal stops ([c]) by an adult with an articulation disorder associated with a repaired cleft palate. Results: Two novel observations were made from the instrumental data. First, although /t/ and /k/ targets were judged by phonetically trained listeners as homophonous (i.e., both produced as [c]), the EPG data revealed that the place of articulation for the [c] produced for /t/ was more anterior than the place of articulation for the [c] produced for /k/. Second, production of palatal stops involved lateral release followed by a variable period of lateral friction. Measurements made from the instrumental data quantified the temporal extent of lateral friction during the aspiration period. Conclusions: These observations merit further systematic investigation in cleft palate speech, and the procedures reported in this study are considered appropriate for such future research.
