Bridging the gap between L2 speech perception research and phonological theory

A series of experiments shows that Spanish learners of English acquire the ship-sheep contrast in a way specific to their target dialect (Scottish or Southern British English) and that many learners exhibit a perceptual strategy found in neither Spanish nor English. To account for these facts as well as for the findings of earlier research on second language (L2) speech perception, we provide an Optimality Theoretic model of phonological categorization that comes with a formal learning algorithm for its acquisition. Within this model, the dialect-dependent and L2-specific facts provide evidence for the hypotheses of Full Transfer and Full Access
