The language of children with Autism Spectrum Disorder (ASD) is sometimes described by clinicians as having a pedantic quality: overly formal, adult-like, and inappropriate for the conversational setting. The term, pedantic speech, does not have a standard definition in ASD literature, but typically includes speech that is lengthy, containing too much detail, and more similar to written language than spoken language. Current measures of pedantic speech in ASD are subjective in nature and may not be consistent across examiners. Few automated measures have been proposed that do not involve additional manual coding by a transcriber. We have developed a fully automated method that attempts to measure pedantry at the unigram-level.
