The current study aimed to provide a comprehensive analysis of linguopalatal contact patterns in participants with acquired apraxia of speech (AOS). Tongue-to-palate contacts were recorded for three participants with AOS during consonant singletons and consonant clusters using the Reading Electropalatograph (EPG3) system. Amount and pattern of linguopalatal contact were analysed using qualitative and quantitative analysis methods and the degree of spatial variability was quantified. The results obtained for each of the apraxic speakers were individually compared to those obtained by a control group (n = 5). Misdirected articulatory gestures and distorted spatial configurations for alveolar fricatives were detected in the linguopalatal contact patterns recorded for each of the participants with AOS. Lingual overshoot, right-side dominant contact, and increased spatial variability were also evidenced by some participants. True omission errors were absent. Overall, the combination of qualitative and quantitative analysis techniques proved valuable in providing a comprehensive analysis of linguopalatal contact in AOS. Results provided support for a motoric account of articulatory and prosodic deficits in AOS. (Contains 5 figures and 7 tables.)
