Abstract
The speech of individuals with autism spectrum disorder (ASD) has been perceptually judged as less clear and articulate than the speech of their typically developing (TD) peers. Some evidence suggests that reduced articulatory precision may contribute to negative listener impressions of individuals with ASD. Using an objective, holistic measure of articulatory precision, findings from a corpus of 900 semi-structured speech samples indicate that individuals with ASD produced speech with reduced articulatory precision compared to TD peers. In both TD populations and populations with ASD, children were less precise than adults. While more research is required to substantiate these preliminary findings, articulatory precision may be a potential avenue of further investigation as a diagnostic speech marker for ASD.
