This longitudinal study examines the acquisition of target-like patterns of phonological variation by 17 second language (L2) French learners during a semester or year of study abroad (SA) in France. In this study, speech data from sociolinguistic interviews conducted before, during, and after the SA period provide evidence for the emergent acquisition of a phonological variable showing sociostylistic variation in first language (L1) speech: the reduction of word-final obstruent-liquid clusters, as in: notre maison [no tʁ(ə) mɛ ʒɔ̃] ~ [not mɛ ʒɔ̃] ‘our house’; c’est incroyable [se tɛ̃ kʁɔ ja bl(ə)] ~ [se tɛ̃ kʁɔ jab] ‘it’s incredible’. Additionally, speech data are compared and correlated with the results of a social network strength scale designed by the researcher for the SA learning context. Results suggest that sociostylistic variation patterns among learners are constrained by linguistic factors similar to those operating on L1 speech, such as lexical effects, and that time in the target language (TL) environment is a significant predictor of variation. Results also demonstrate that although social network strength is not a significant predictor of variation at a group level, speaker gender is, and learner patterns reflect the gendered speech norms of the TL community.
