Categorization of second language accents by bilingual and multilingual listeners.

Abstract

This study examines how listeners categorize second language (L2) accents and how their linguistic background affects this categorization. Ninety-eight adult bilingual and multilingual Greek listeners categorized accents in a familiar (British English)-unfamiliar (Australian English) L2 accent condition. Data were collected through an online survey and analysed using binomial mixed-effects models and signal detection analysis. The results demonstrated that both bilinguals and multilinguals exhibited low performance in the task, potentially due to their decreased familiarity with the Australian English accent and the fact that the two accents are phonetically similar. However, despite both groups' low performance, multilinguals outperformed bilinguals in accent categorization accuracy. This advantage could be attributed to a combination of cognitive and social dynamics. Results expand upon prior research, indicating that exposure to accent variation enhances listeners' abilities to categorize non-native accents. The study provides important theoretical implications for the perception of accents and practical insights into foreign language learning and multilingual communication.
