Pronunciation teaching is often based on assumptions that learners are monolingual speakers, with the sound system of their native language determining the segmental and suprasegmental difficulties that mark learners’ foreign accents. However, many, if not a majority of speakers of other languages come to pronunciation with more than one language under their command. These bilingual/multilingual speakers are the norm in a globalized world, but how we teach pronunciation rarely accounts for the knowledge and skills these speakers bring to the learning of pronunciation. This chapter describes how the characteristics of bilingual speakers suggest how pronunciation teaching can be reimagined to take into account the range and flexibility of bilingual speakers in using multiple languages. Specifically, we argue that taking a nativeness viewpoint is inconsistent with taking a bilingual viewpoint and calls for pedagogical techniques that build on the kinds of needs bilingual speakers have in pronouncing additional languages.

This chapter focuses on the learning and teaching of second language pronunciation. It starts by asking basic questions such as: Why is it so hard to sound like a “native speaker”? and Should second language learners even sound like native speakers? The chapter reviews the components of pronunciation including phoneme, segmentals, and suprasegmentals. It then explores the topics of comprehensibility, intelligibility, and accentedness, in order to consider which are most important for second language communication and learning. It argues that native-like pronunciation should not be the goal of pronunciation instruction; rather, the goal should be comprehensibility (i.e., how well a second language learner is understood by a listener). It reviews other issues related to pronunciation learning such as the distinction between receptive and productive knowledge, the role of identity in maintaining a first-language accent, and the role that biology plays in affecting second language pronunciation mastery. Finally, the chapter explores both explicit and implicit methods of pronunciation instruction.

In the Finale we examine to what extent Causal Mechanism can be seen as a descendant of the original notion of mechanism developed in seventeenth century, by examining possible extensions of the seventeenth-century notion of mechanism and discussing whether they can be used to characterise mechanism as a concept-in-use. We identify two conditions that a biological explanation has to satisfy in order to count as mechanistic, both of which were central in Old Mechanism: the condition of intelligibility and the condition of the priority of the parts over the whole. We use these two conditions to distinguish between two notions of mechanism: a more narrow one that incorporates both the intelligibility condition and the condition of the priority of the parts and a broader one that incorporates only the intelligibility condition and is thus a weakened form of mechanism. We claim that an account of mechanism as a concept-in-use requires the weakened notion, which when viewed in terms of Causal Mechanism has nevertheless enough content so that it can be seen as a descendant of the original concept.

Aristotle maintains that defining nous requires first defining its activity, which requires first having considered its objects, intelligible beings. This chapter is about the nature of these objects: what about them makes them intelligible? My principal proposals will be that what makes them intelligible is that they are separate or unmixed, and that because, insofar as they are intelligible, they are, in their essence, activity. I am not unaware that this makes it sound as though Aristotle takes intelligibility to consist in some kind of nous. But he himself virtually says as much, when he claims that nous is the form of its objects (lit. εἶδος εἰδῶν); besides it is a result he is committed to by the doctrines that nous is intelligible and that there is something that intelligible objects all are in common; for the alternative, as he himself says, is to suppose that nous “will have something mixed-in, which makes it intelligible just like the rest.” The challenge, then, is not to steer clear of this result, but to make sense of it. My proposal will be that the key lies in realizing that and why Aristotle thinks intelligibility is a creature of nous.

Aristotle maintains that defining "intelligence" (nous) requires first defining its activity, “understanding” or “insight” (noēsis) which requires first having considered its objects, intelligible beings (noēta). This chapter is about the nature of these objects: what about them makes them intelligible? My principal proposals are that what makes them intelligible is that they are "separate" and "unmixed," and that because, insofar as they are intelligible, they are, in their essence, "activity."’ I am aware this makes it sound as though Aristotle takes intelligibility to consist in some kind of intelligence. But in fact this is a result he is committed to, by the doctrines that intelligence is intelligible and that there is something that intelligible objects "all are in common"; for the alternative, as he himself says, is to suppose that intelligence "will have something mixed-in, which makes it intelligible just like the rest." The challenge, then, is not to steer clear of this result, but to make sense of it. My proposal is that the key to this lies in realizing that and why Aristotle thinks of intelligibility as a creature of intelligence.

In this chapter, we review phonetics in pronunciation teaching and learning from a historical perspective, before going on to look at paradigms for pronunciation and second language (L2) phonology with a focus on phonetic issues. Research identifying the importance of access to phonetic cues, auditory and visual, both in experimental and classroom settings, is presented, demonstrating the increasing emphasis on technology in this field. We then move on to recommendations for teacher training, with a review of approaches to describing intonation for pedagogic purposes. Finally, we present suggestions for the future of pronunciation teaching and learning.

This chapter provides an overview of research on heritage language (HL) sound systems, with a focus on areas of convergence and divergence among heritage speakers (HSs), native speakers (NSs) who continue to be dominant in the language, and second language learners (L2ers) who acquired the language later in life. Drawing on data from a wide range of HLs, the chapter addresses both phonetic (articulatory, acoustic, perceptual) and phonological (phonemic, distributional, phonotactic) aspects of the HL sound system, as well as that of the majority language, in light of theories of bilingual speech and variables previously studied as predictors of HSs’ linguistic behavior. Despite the diversity of results reviewed, several recurring themes emerge, including intermediate patterning between NSs and L2ers, a higher level of performance in perception than production, and individual variability. In particular, the depth and the accessibility of HSs’ knowledge of the HL sound system show considerable variation related to structural linguistic factors, demographic and sociolinguistic factors, input and usage-based factors, and methodological factors. In addition to summarizing the areas in which there is an emerging consensus, the chapter points out a number of remaining questions that pave the way for future research on HL sound systems.

This chapter addresses the puzzling question of why, in his Timaeus, Plato combines two very different topics: a cosmogony and account of the universe, on the one hand, and a story about the moral actions of ancient Athens, Atlantis, and Egypt, on the other. Sattler argues that the key to understanding the relation between these two parts is recognition that, in Plato’s view, they confront us with a structurally similar problem: how we are to account for the intelligibility of processes in the phenomenal world. Sattler shows that Plato no longer chooses to solve this problem by tying intelligibility to complete uniformity, as he did in the Republic, but by tying intelligibility to a rule – to norms and laws for actions in the human cultural realm, and to ratios and descriptive rules for the motions of the heavenly bodies in the natural realm. While Plato also accounts for the concerns specific to ethics and physics, the attempt to understand processes raises similar problems for him in both realms. Recurring natural catastrophes, such as floods and fires, appear as one kind of natural regularity in this Platonic account.

Nature for Plotinus is near the limit of intelligibility in the hierarchical universe. It is the lowest part of the soul of the cosmos. Hence, all problems in cosmology and biology, prior to their solution, need to be situated within the framework of the ultimate metaphysical explanatory principles of the One, Intellect and Soul. This chapter explores the sense in which Plotinus is and is not receptive of panpsychism, the contemporary philosophical view according to which mentality or consciousness is ubiquitous in the world. Plotinus argues for the idea that nature contemplates which seems, perhaps surprisingly, compatible with the radically anti-Platonic naturalism of panpsychists.

This study examines the effects of auditory priming on second-language (L2) speech production. Mandarin learners of English were presented with an English vowel as an auditory prime followed by an English target word containing either a tenseness congruent (e.g., prime: /i/ – target: “peach”) or incongruent (e.g. prime: /i/ – target: “pitch”) vowel. Pronunciation of the target vowel was measured in terms of duration and formant frequency, as well as intelligibility by native English listeners. Results show a more English-like formant frequency distribution and an increase in intelligibility of the /i/ and /ɪ/ productions in the congruent relative to incongruent condition, suggesting that auditory speech information can positively affect the pronunciation of difficult L2 speech contrasts.

Research showed that the interlanguage-speech intelligibility benefit (ISIB) effect progressively disappeared in Chinese speakers of English as their English proficiency increased and their exposure to Chinese-accented English decreased. As a result, ISIB effects were obvious in less proficient speakers. We explore the hypothesis that ISIB is still present in proficient L2 English speakers when tasks go beyond sound transcription and relate intelligibility to more complex sound-meaning mappings. Results showed that, in general, native English speakers outperformed Chinese speakers of English showing no evidence of an overall ISIB effect despite that Chinese speakers of English rated Chinese-accented sentences as more comprehensible. Only in the compound vs noun contrasts (e.g., ‘bluebird’ vs. ‘blue bird’), Chinese speakers of English outperformed native English speakers in the Chinese-accented stimuli, showing a mild ISIB-L effect. This modest evidence in support of ISIB encourages further exploration on aspects of sound perception that could affect ISIB in proficient L2 speakers.

It has been suggested that co-textual and contextual cues do not contribute much to phonological intelligibility in ELF interactions, since many non-native ELF users seem largely unable to draw on such cues when processing each other’s accents (Jenkins 2000). This small-scale, qualitative study investigates the role played by co-textual and contextual information in instances of phonological unintelligibility in ELF interactions. The results suggest that the non-native ELF users in this study tend to ‘interpret’ rather than ‘decode’ the incoming acoustic signal in relation to co-textual and contextual cues, provided they are available. The findings also indicate that such cues are not always beneficial to the listener, as they can also ‘mislead’ them by supporting an incorrect identification of a word.

Chapter 18 first identifies the theoretical framework and key components of a pronunciation learning approach. It then shares the results of a small-scale study that investigated the efficacy of the approach in a tutoring setting. The results provided empirical evidence supporting the approach and revealed seven factors that contributed to changes in the tutors’ perceptions of their expert knowledge, agency, and professional identity as pronunciation teachers.

This chapter explores ideas about ‘(non-)native’ speakers of English, with particular reference to the professional context of teaching English to speakers of other languages (TESOL). The use of ‘(non-)native’ speaker to describe a person’s use of English remains common in a variety of domains, despite much scholarly and professional argument against the term. Given that learners and teachers comprise the educational context of this chapter, I have chosen to focus on the native and non-native speakers themselves, rather than on their (so-called) native and non-native uses of English. In doing so, I hope not to fall into the trap of thinking of people as permanent members of closed categories, but, on the contrary, show how we might raise awareness of the (potentially negative) effects of such thinking on speakers of English, in the TESOL profession.

This chapter aims to engage with wider discussions in this volume regarding ontologies of English and how language can be productively conceptualized by English teachers, learners/users, and other stakeholders. As indicated by the title, the work is intended to make a specific contribution towards uncovering complexity in ontologies of language that do not map cleanly onto dichotomies such as ‘monolithic versus plurilithic’ (Hall, 2013), ‘difference versus deficit’, or ‘standards-based versus intelligibility-based’. As also indicated, these ontological discussions are framed by a study carried out in a lingua franca context of pedagogy and usage, where (1) Japanese voluntary workers use English as a Lingua Franca to communicate with local interlocutors in diverse global locations and (2) an English language course is taken by these volunteers prior to their departure from Japan that is specifically designed to facilitate that communication. Further details on this context are provided in the following section before the focus returns to conceptions of English.
