Does Speaker Race Affect the Assessment of Children's Speech Accuracy? A Comparison of Speech-Language Pathologists and Clinically Untrained Listeners.

Abstract

Some pronunciation patterns that are normal in 1 dialect might represent an error in another dialect (i.e., [koʊl] for cold, which is typical in African American English [AAE] but an error in many other dialects of English). This study examined whether trained speech-language pathologists and untrained listeners accommodate for presumed speaker dialect when rating children's productions of words. This study also explored whether effects of presumed race on perceived speech accuracy are mediated by individuals' knowledge and beliefs about AAE and their implicit attitudes about race. Multiple groups of listeners rated the accuracy of a set of children's productions of words that have a distinct pronunciation in AAE. These were presented in 1 of 3 conditions: paired with no visual stimulus (to assess baseline accuracy) or paired with either African American children's faces (to suggest that the speaker uses AAE) or European American children's faces (to suggest that the speaker does not use AAE). Listeners also completed a set of measures of knowledge and attitudes about AAE and race, taken from previous studies. Individuals in both groups rated children's productions more accurately when they were presented with African American children's faces than when paired with European American faces. The magnitude of this effect was generally similar across the 2 groups and was generally strongest for words that had been judged in the baseline condition to contain an error. None of the individual-differences measures predicted ratings. Assumptions about speaker attributes affect individuals' assessment of children's production accuracy. These effects are robust across trained and untrained listeners and cannot be predicted by existing measures of knowledge and attitudes about AAE and race.
