Dysarthria is a motor speech disorder that results in reduced speech intelligibility and impacts functional participation for many children with cerebral palsy (CP) and other neurodevelopmental disorders. The speech characteristics associated with pediatric dysarthria are heterogeneous and can be difficult to identify in young children with developing speech systems. Currently, no system exists for identifying subtypes of pediatric dysarthria in a way that is designed for children, based on quantitative data of children's speech, and can be used to direct treatment. The present project aimed to investigate characteristics of connected speech that indicate the presence of dysarthria in young children, and to provide a foundation for developing a novel pediatric dysarthria classification system by identifying quantitatively-derived subgroups of children with different constellations of speech features. Two studies were conducted in order to address these goals.

520 $a Dysarthria is a motor speech disorder that results in reduced speech intelligibility and impacts functional participation for many children with cerebral palsy (CP) and other neurodevelopmental disorders. The speech characteristics associated with pediatric dysarthria are heterogeneous and can be difficult to identify in young children with developing speech systems. Currently, no system exists for identifying subtypes of pediatric dysarthria in a way that is designed for children, based on quantitative data of children's speech, and can be used to direct treatment. The present project aimed to investigate characteristics of connected speech that indicate the presence of dysarthria in young children, and to provide a foundation for developing a novel pediatric dysarthria classification system by identifying quantitatively-derived subgroups of children with different constellations of speech features. Two studies were conducted in order to address these goals.
520 $a Six acoustic and perceptual speech variables representing different speech subsystems were analyzed in sentence productions of 20, 5-year-old children with CP and dysarthria (speech motor impairment (SMI) group), and 20 age and sex-matched typically-developing children (TD group). In Study 1, children in the SMI and TD groups were compared on each speech variable, and multiple logistic regression was used to identify measures that best predicted dysarthria diagnosis. In Study 2, hierarchical cluster analysis was used to identify naturally occurring subgroups of children with similar patterns of speech features, and the relationship between speech patterns and intelligibility was examined.
520 $a Results of Study 1 showed that children with CP and dysarthria differed from typically-developing children on measures of each speech subsystem in connected speech, and that together, two acoustic measures (articulation rate and F2 range of diphthongs) distinguished children with dysarthria from typically-developing children with 87.5% accuracy. Results of Study 2 revealed three clusters of children with CP and dysarthria with distinct speech patterns, two of which did not significantly differ in intelligibility. These findings contribute novel information about characteristics of connected speech in children with dysarthria, suggest candidate speech measures that may be useful for early identification of children with dysarthria, and provide preliminary characterization of distinct speech profiles among children with dysarthria.
