This award funds research to develop a diagnostic tool for differentiating childhood apraxia of speech and dysarthria in preschoolers by establishing normative speech feature data and classification methods.
Description
The project aims to develop and validate a norm-referenced assessment protocol to identify atypical speech features in children aged 3-6, facilitating early and accurate diagnosis of childhood apraxia of speech (CAS) and dysarthria. The research involves establishing growth curves for speech features, identifying classification features using a random forest approach, and analyzing data-driven clusters of speech features to improve diagnostic utility.
