Chapter 22: The phonetics and phonology of early bilinguals

This chapter provides a thorough, up-to-date review of the literature on the phonetics and phonology of early bilinguals. It pulls together studies from a range of bilingual settings, including bilingual societies and heritage language contexts. While the chapter mostly reviews evidence from adolescent and adult participants, it also makes reference to the child bilingualism literature, where appropriate. The chapter first reviews studies on the accents of early versus late bilinguals, followed by a discussion of the various explanatory accounts for the observed differences between these two groups. Subsequently, the critical significance of early linguistic experience on bilingual speech patterns is considered, with particular reference to the evidence from childhood overhearers and international adoptees. The following sections then review studies comparing simultaneous and early sequential bilinguals, and those exploring the role of language dominance, continued use, the language of the environment in bilinguals’ pronunciation patterns, and the role of sociolinguistic factors in early bilingual speech patterns. The chapter concludes with suggestions for future research.
