Second language phonology as redeployment of L1 phonological knowledge

This article presents research showing that second language (L2) learners do not have deficient representations and they are capable of acquiring structures that are absent from their first language (L 1). The Redeployment Hypothesis-which claims that L2 phonologies include novel representations created via redeployment of L1 phonological components-is consistent with data from several domains, including acquisition of phonological features, syllable structure, moraic structure, and metrical structure. Moreover, it is shown that input prominence plays a role in L2 acquisition, and that language learners are sensitive to robust phonetic cues. Finally, studies done on interlingual homographs and homophones argue for non-selective access to the bilingual lexicon, suggesting that the language processing capacity is always engaged.
