The Phonetics and Phonology of Bilingualism
This chapter provides a selective overview of recent research on the phonetics and phonology of bilingualism. The central idea put forth in the chapter is that, in bilingualism and second-language learning, cross-language categories are involved in complex interactions that can take many forms, including assimilations and dissimilations. The sound categories of the two languages of a bilingual seem to coexist in a common representational network and appear to be activated simultaneously in the processing of speech in real time, but some degree of specificity is attested. The chapter then goes on to explore some of the characteristics of cross-language sound interactions, including the fact that these interactions are pliable and appear to be mediated by the structure of the lexicon.
