Second/foreign language (L2) speech production is a complex process requiring individuals’ combined efforts to utilize various processing components such as conceptualiser, formulator, and articulator. Since the publication of Pim Levelt’s book Speaking – From Intention to Articulation in 1989, a considerable number of studies have examined L2 speech production in the field of neuroscience with a particular focus on the link between speech perception and speech production. Undeniably, a neurolinguistic examination of speech production can enrich our understanding of how human brains compute linguistic information at a cognitive level. However, it is insufficient by only focusing on the neurocognitive dimension of speech production, given that individuals’ speech production can be subject to various individual differences factors, either cognitively, affectively, or socio-culturally. It is, therefore, necessary to move beyond the neurocognitive understanding of speech production by taking every possible perspective into consideration. Individual difference, as an umbrella term, covers psychological traits, personal characteristics, cognitive and emotional components that distinguish learners from each other. Given that individual difference factors can reveal disparities in L2 learning and performance among learners, such factors have attracted researchers’ growing interest concerning their influences on L2 speech processing, their relationships with L2 speech performance, and their contributions to L2 speech development. Nevertheless, our understanding of L2 speech production is not only insufficient compared to other L2 skills such as writing and reading, but also limited to the neurocognitive account of L2 speech production. More research, therefore, is in urgent need to uncover the influence of various individual differences factors on L2 speech production from multidisciplinary perspectives.

Including contributions from a team of world-renowned international scholars, this volume is a state-of-the-art survey of second language speech research, showcasing new empirical studies alongside critical reviews of existing influential speech learning models. It presents a revised version of Flege's Speech Learning Model (SLM-r) for the first time, an update on a cornerstone of second language research. Chapters are grouped into five thematic areas: theoretical progress, segmental acquisition, acquiring suprasegmental features, accentedness and acoustic features, and cognitive and psychological variables. Every chapter provides new empirical evidence, offering new insights as well as challenges on aspects of the second language speech acquisition process. Comprehensive in its coverage, this book summarises the state of current research in second language phonology, and aims to shape and inspire future research in the field. It is an essential resource for academic researchers and students of second language acquisition, applied linguistics and phonetics and phonology.

This book addresses important issues of speech processing and language learning in Chinese. It highlights perception and production of speech in healthy and clinical populations and in children and adults. This book provides diverse perspectives and reviews of cutting-edge research in past decades on how Chinese speech is processed and learned. Along with each chapter, future research directions have been discussed. With these unique features and the broad coverage of topics, this book appeals to not only scholars and students who study speech perception in preverbal infants and in children and adults learning Chinese, but also to teachers with interests in pedagogical applications in teaching Chinese as Second Language.

The scope of individual learner differences is broad, yet there is no current, comprehensive, and unified volume that provides an overview of the considerable amount of research conducted on various language learner differences, until now.

A cogent, freshly written synthesis of new and classic work on crosslinguistic influence, or language transfer, this book is an authoritative account of transfer in second-language learning and its consequences for language and thought. It covers transfer in both production and comprehension, and discusses the distinction between semantic and conceptual transfer, lateral transfer, and reverse transfer. The book is ideal as a text for upper-level undergraduate and graduate courses in bilingualism, second language acquisition, psycholinguistics, and cognitive psychology, and will also be of interest to researchers in these areas.

No sound class requires so much basic knowledge of phonology, acoustics, aerodynamics, and speech production as obstruents (turbulent sounds) do. This book is intended to bridge a gap by introducing the reader to the world of obstruents from a multidisciplinary perspective. It starts with a review of typological processes, continues with various contributions to the phonetics-phonology interface, explains the realization of specific turbulent sounds in endangered languages, and finishes with surveys of obstruents from a sociophonetic, physical and pathological perspective.

This Handbook is a comprehensive volume outlining the foremost issues regarding research and teaching of second language speaking, examining such diverse topics as cognitive processing, articulation, knowledge of pragmatics, instruction in sub-components of speaking (e.g., grammar, pronunciation, and vocabulary) and the attrition of the first language. Outstanding academics have contributed chapters to provide an integrated and inclusive perspective on oral language skills. Specialized contexts for speaking are also explored (e.g., English as a Lingua Franca, workplace, and interpreting). The Routledge Handbook of Second Language Acquisition and Speaking will be an indispensable resource for students and scholars in applied linguistics, cognitive psychology, linguistics, and education.

Language Origin: A Multidisciplinary Approach presents a synthesis of viewpoints and data on linguistic, psychological, anatomical and behavioral studies on living species of Primates and provides a comparative framework for the evaluation of paleoanthropological studies. This double endeavor makes it possible to direct new research on the nature and evolution of human language and cognition. The book is directed to students of linguistics, biology, anthropoloy, anatomy, physiology, neurology, psychology, archeology, paleontology, and other related fields. A better understanding of speech pathology may stem from a better understanding of the relationship of human communication to the evolution of our species. The book is conceived as a timely contribution to such knowledge since it allows, for the first time, a systematic assessment of the origins of human language from a comprehensive array of scientific viewpoints.

Foundations of Language Development: A Multidisciplinary Approach, Volume 1 provides information pertinent to the important discoveries and issues in the area of language development. This book covers important topics, including language policy, language rehabilitation, and language in the classroom. Organized into three parts encompassing 19 chapters, this volume begins with an overview of the relationship between animal communication and language proper. This text then examines the early metaphysical views as to the origin of speech and explores the probable nature of the language employed by early man. Other chapters consider the growing conception that language is essentially a localizable cerebral function. This book discusses as well the shortcomings of speech as a means of human communication. The final chapter deals with a comparison of child language with deteriorated language in senile dementia. This book is a valuable resource for linguists and readers who are faced with practical decisions concerning language.

The Routledge Handbook of Second Language Acquisition and Individual Differences provides a thorough, in-depth discussion of the theory, research, and pedagogy pertaining to the role individual difference (ID) factors play in second language acquisition (SLA). It goes beyond the traditional repertoire and includes 32 chapters covering a full spectrum of topics on learners’ cognitive, conative, affective, and demographic/sociocultural variation. The volume examines IDs from two perspectives: one is how each ID variable is associated with learning behaviors, processes, and outcomes; the other is how each domain of SLA, such as vocabulary or reading, is affected by clusters of ID variables. The volume also includes a section on the common methods used in ID research, including data elicitation instruments such as surveys, interviews, and psychometric testing, as well as methods of data analysis such as structural equation modeling. The book is a must-read for any second language researcher or applied linguist interested in investigating the effects of IDs on language learning, and for any educator interested in taking account of learners’ individual differences to maximize the effects of second language instruction.
