In bilingual speech, the sound systems of a speaker’s first (L1) and second (L2) languages often interact, which may result in cross-linguistic phonetic influences in both.  Focusing on early Indian English bilinguals with well established L1-L2 categories, this talk explores the interaction between accommodation and drift, as well as the link between production and perception, by examining whether L2 accommodation can trigger L1 drift across modalities. The speakers exhibited L2 accommodation towards a different variety (American English), but the L2 changes did not extend to the production of their L1 (Hindi and Telugu) categories. However, their L1 perception showed significant drift that was inconsistently aligned with the direction and amount of L1 production drift. These findings reveal that in early bilinguals, L1 production remains robust against L2 accommodation, while L1 perception may be more malleable. Furthermore, they provide evidence supporting an indirect link between production and perception, which allows the two modalities to change partly independently.
