Studies have found that children with Autism Spectrum Disorder (ASD) use the filler "um" at a significantly lower rate than children with Typical Development (TD), with no difference in "uh" usage. Examiners' filler usage in similar language samples has not been studied. We investigated whether differences in "um" and "uh" usage between ASD and TD children also appear in the speech of their conversational partners: the examiners. Objectives: (1) Compare examiner usage rates of "um" and "uh" when conversing with ASD vs. TD participants; (2) Investigate whether within-group differences in examiner filler usage vary by participant age, intellectual ability, expressive language ability, or autism symptom severity.
