Previous research on the plasticity of the perceptual system in early and late bilingualism tested through lexical decision tasks has identified asymmetries in the categorization accuracy of contrastive sounds due to extensive exposure to two languages. Such asymmetries are attributable to either properties of the bilingual lexicon or phonetic weakening of contastive sounds, or both. This talk will present evidence from bilingual populations differing in amount of use of their L1 and L2 partly lending support to a phonetic weakening hypothesis. Perception was examined through accuracy and latency measures of degree of categoriality, whereas production was assessed through measures of degree of contrast categoriality (spectral distance scores) in cognate and non-cognate words. These data are discussed with a focus on the special role of cognates in bilingual speech production.
