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.

This chapter outlines studies within the domain of speech perception by bilingual adult listeners. I first discuss studies that have examined bilinguals’ perception of L1 and/or L2 speech segments, as well as those that have tested perception of unfamiliar, non-native speech segments. In turn, I examine each of the factors that are known to affect bilinguals’ perception of speech, which include age of L2 acquisition, effects of L1:L2 usage as they pertain to language dominance and proficiency, and short-term contextual effects on speech perception. I also provide an overview of the literature on bilinguals’ perception of suprasegmentals. Finally, I explore what I think are some of the crucial questions facing the field of bilingual speech perception.

This chapter reviews available information on the phonetics and phonology of indigenous language bilinguals published in the last few decades, focusing on both of the bilinguals’ languages, the interplay between their phonological systems, and the phonetic realizations of the sounds present in their languages. We understand indigenous languages as predominantly minority languages spoken by linguistically distinct and often socially marginalized and vulnerable ethnic groups, autochthonous to a specific region of the world, and found in diglossias with majority international languages resulting from colonization. Indigenous language bilingualism is usually small-scale and involves speaking at least one minority indigenous language and at least one majority international language, thus being a step toward a seemingly inevitable language shift and in some cases an eventual indigenous language disappearance. The dynamic and asymmetrical character of indigenous bilingualism, along with the vast number of language combinations and the speaker community size differences between the members of these language pairs, sets it apart from other types of bilingualism considered in this book.

In this chapter, we move from discussing English segmentals – individual consonant and vowel sounds – to suprasegmentals, the units of sound above the level of the segment. This includes stress, pitch, and tone, and extends above individual vowel and consonants to syllables, words, phrases, and sentences. At the core of our discussion of suprasegmentals is the syllable, which can be defined as a unit of organization for sound sequences. Every word is made up of minimally one syllable; in some languages, including English, words often contain multiple syllables.

We begin the chapter by examining what we mean by 'syllable', and the components of a syllable, including the onset, nucleus, and coda. We then examine syllable inventories cross-linguistically, with a special focus on the languages that influence varieties of English. An overview of English syllable structure is then provided, with a focus on how syllable structure varies across varieties. In the final section of the chapter, you will be guided through exercises designed to check your understanding of the content of the chapter and to analyse your own English syllable inventory.

This chapter on Romance phonology reviews several phenomena that can be qualified as typologically rare. Some of the phenomena examined are rarely documented within Romance but are relatively common in other language families, while others are hardly attested in the world’s languages but are present to some degree in Romance. Their relative frequency across languages and geographical distribution have been assessed with the help of three online databases that are publicly available: PHOIBLE, WALS, and the World Phonotactics Database. In addition, the challenges that these phenomena represent for phonological theory are also briefly considered. The topics examined in this chapter concern (i) phoneme inventories; (ii) syllable structure, with a focus on consonantal clusters; (iii) segmental processes involving glides, nasal place neutralization, lenition and fortition, and metathesis, among others; and (iv) issues at the morphology–phonology interface involving suprasegmentals.
