This study investigates the effect of L2 (Spanish) use on Catalan–Spanish bilinguals’ ability to accurately perceive and produce two contrastive native Catalan vowel categories, /e/ and /e/. Participants were L1 Catalan highly proficient Catalan–Spanish bilinguals differing in amount of daily exposure/use of Catalan (low: 40%–70% vs. high: 80%–100%). Perceptual accuracy was assessed through speeded categorization and AXB discrimination tasks based on a 10-step vowel continuum (/e/–/e/). Production accuracy was assessed by eliciting /e/ tokens in Catalan cognate and noncognate words. The results indicated that participants using Spanish more frequently discriminated Catalan vowels /e/ and /e/ less accurately and significantly more slowly and had a more Spanish-like acoustic target in the production of Catalan /e/, particularly in cognate words. These results are consistent with the view that, in a language contact context, extensive L2 experience affects L1 sound categories.
