Direct linkLevy, Erika S.; Chang, Younghwa M.; Hwang, KyungHae; McAuliffe, Megan J. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Children with dysarthria secondary to cerebral palsy may experience reduced speech intelligibility and diminished communicative participation. However, minimal research has been conducted examining the outcomes of behavioral speech treatments in this population. This study examined the effect of Speech Intelligibility Treatment (SIT), a…

Fletcher, Annalise R.; Wisler, Alan A.; McAuliffe, Megan J.; Lansford, Kaitlin L.; Liss, Julie M. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: Behavioral speech modifications have variable effects on the intelligibility of speakers with dysarthria. In the companion article, a significant relationship was found between measures of speakers' baseline speech and their intelligibility gains following cues to speak louder and reduce rate (Fletcher, McAuliffe, Lansford, Sinex, &…

Fletcher, Annalise R.; McAuliffe, Megan J.; Lansford, Kaitlin L.; Liss, Julie M. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The strength of the relationship between vowel centralization measures and perceptual ratings of dysarthria severity has varied considerably across reports. This article evaluates methods of acoustic-perceptual analysis to determine whether procedural changes can strengthen the association between these measures. Method: Sixty-one…

Fletcher, Annalise R.; McAuliffe, Megan J.; Lansford, Kaitlin L.; Sinex, Donal G.; Liss, Julie M. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: Across the treatment literature, behavioral speech modifications have produced variable intelligibility changes in speakers with dysarthria. This study is the first of two articles exploring whether measurements of baseline speech features can predict speakers' responses to these modifications. Method: Fifty speakers (7 older individuals…

McAuliffe, Megan J.; Kerr, Sarah E.; Gibson, Elizabeth M. R.; Anderson, Tim; LaShell, Patrick J. – Journal of Speech, Language, and Hearing Research, 2014
Purpose: To determine how increased vocal loudness and reduced speech rate affect listeners' cognitive-perceptual processing of hypokinetic dysarthric speech associated with Parkinson's disease. Method: Fifty-one healthy listener participants completed a speech perception experiment. Listeners repeated phrases produced by 5 individuals…

McAuliffe, Megan J.; Ward, Elizabeth C.; Murdoch, Bruce E. – Clinical Linguistics & Phonetics, 2006
Previous investigations employing electropalatography (EPG) have identified articulatory timing deficits in individuals with acquired dysarthria. However, this technology is yet to be applied to the articulatory timing disturbance present in Parkinson's disease (PD). As a result, the current investigation aimed to use EPG to comprehensively…
