“Does this make sense?”: The effect of matching guise in regional accent on grammatical acceptability judgments

Syntax and sociophonetics are typically treated as wildly disjointed (possibly even incompatible) theoretical pursuits. This paper seeks to unite sociophonetic speech perception and syntax research by presenting participants with matching or mismatching social expectations during a structural grammaticality judgment task. Place is the unifying social association between guise and structure. Participants completed a between-subjects matched guise survey with place-based grammatical structures spoken in either a matching place-based, local accent or a nonlocal accent. Place-based structures are consistently rated more acceptable in the local accent than the nonlocal. These results suggest that judgment of grammaticality results from an interplay of sociocultural expectations with accent and sentence structure. Judgment of structural grammaticality is not independent of social expectation.
