Abstract

A growing body of research finds that neurotypical autistic traits are predictive of speech perception and language comprehension patterns, but considerably less is known about the influence of these traits on speech production. In this brief report, we present an analysis of vowel productions from 74 American English speakers who participated in a communicative speaking task. Results show higher autistic trait load to be broadly and inversely related to spectral correlates of vowel intelligibility. However, the statistical significance of this relationship is specific to autistic traits along the pragmatic communication dimension, and limited to female speakers.

However, studies have often found utterance/phrase-initial position to have unreliable effects on articulatory targets for vowels (e.g. Cho & Keating, 2009). One possibility is that the effect for phrase position here reflects our speakers’ interpreting utterance-initial target words as the focused element in a focus-topic construction; such contrasts in information structure have been shown to influence articulatory dynamics independent of prosodic structure (Mücke & Grice, 2014). An interesting question that we leave for future research is whether autistic trait load might predict the robustness with which neurotypical speakers encode information structure in fine-grained articulatory or acoustic measures. (See Krüger et al., 2018 for relevant findings from speakers drawn from the clinical population).
