It has been traditional in phonetic research to characterize monophthongs using a set of static formant frequencies, i.e., formant frequencies taken from a single time-point in the vowel or averaged over the time-course of the vowel. However, over the last twenty years a growing body of research has demonstrated that, at least for a number of dialects of North American English, vowels which are traditionally described as monophthongs often have substantial spectral change. Vowel inherent spectral change has been observed in speakers’ productions, and has also been found to have a substantial effect on listeners’ perception. In terms of acoustics, the traditional categorical distinction between monophthongs and diphthongs can be replaced by a gradient description of dynamic spectral patterns. This book includes chapters addressing various aspects of vowel inherent spectral change (VISC), including theoretical and experimental studies of the perceptually relevant aspects of VISC, the relationship between articulation (vocal-tract trajectories) and VISC, historical changes related VISC, cross-dialect, cross-language, and cross-age-group comparisons of VISC, the effects of VISC on second-language speech learning, and the use of VISC in forensic voice comparison.

In the general study of speech and phonetics, vowels have stood in second place to consonants. But what vowels are, how they differ from one another, how they vary among speakers, and how they are subject to disorder, are questions that require a closer examination. This Handbook presents a comprehensive, cogent, and up-to-date analysis of the vowel, including its typical development in children's speech, description by perceptual and instrumental methods, cross-linguistic and sociolinguistic aspects, and disorders of its production and use. It approaches the problems of vowel production and perception from the viewpoints of physiology, physics, psychology, linguistics, phonetics, phonology, and speech-language pathology. The chapters are logically complementary, and the major sections of the book are like key dimensions of understanding, each adding a perspective and base of knowledge on vowels. The sum total of the chapters is a synthesis of information on vowels that has no precedent.

The last 50 years have witnessed a rapid growth in the understanding of the articulation and the acoustics of vowels. Contemporary theories of speech perception have concentrated on consonant perception, and this volume is intended as a balance to such bias. The authors propose a computational theory of auditory vowel perception, accounting for vowel identification in the face of acoustic differences between speakers and speaking rate and stress. This work lays the foundation for future experimental and computational studies of vowel perception.

The Routledge Handbook of Phonetics provides a comprehensive and up-to-date compilation of research, history and techniques in phonetics. With contributions from 41 prominent authors from North America, Europe, Australia and Japan, and including over 130 figures to illustrate key points, this handbook covers all the most important areas in the field, including: • the history and scope of techniques used, including speech synthesis, vocal tract imaging techniques, and obtaining information on under-researched languages from language archives; • the physiological bases of speech and hearing, including auditory, articulatory, and neural explanations of hearing, speech, and language processes; • theories and models of speech perception and production related to the processing of consonants, vowels, prosody, tone, and intonation; • linguistic phonetics, with discussions of the phonetics-phonology interface, sound change, second language acquisition, sociophonetics, and second language teaching research; • applications and extensions, including phonetics and gender, clinical phonetics, and forensic phonetics. The Routledge Handbook of Phonetics will be indispensable reading for students and practitioners in the fields of speech, language, linguistics and hearing sciences.

This book includes a selection of theoretical and practical accounts of the acquisition of Portuguese from a broad range of linguistic perspectives. This collection is particularly appealing in the broad academic sphere of language acquisition due to the fact that there has yet to be one entirely dedicated to Portuguese as an Additional Language (PAL). This volume showcases the breadth of research being carried out on topics ranging from the acquisition of aspects from the main language modules (syntax, morphology, semantics, phonology, and pragmatics) to applied perspectives involving corpus-based approaches and experimental methodologies. Moreover, we present studies addressing a variety of learning contexts and learner types. The target audience includes researching scholars with a background in second language acquisition studies interested in learning more about the acquisition of Portuguese as an Additional Language from linguistic perspectives.

The relationship between the individual and the community is at the core of sociolinguistic theorizing. To date, most longitudinal research has been conducted on the basis of trend studies, such as replications of cross-sectional studies, or comparisons between present-day cross-sectional data and ‘legacy’ data. While the past few years have seen an increasing interest in panel research, much of this work has been published in a variety of formats and languages and is thus not easily accessible. This edited volume brings together the major researchers in the field of panel research, highlighting connections and convergences across and between chapters, methods and findings with the aim of initiating a dialogue about best practices and ways forward in sociolinguistic panel studies. By providing, for the first time, a platform for key research on panel data in one coherent edition, this volume aims to shape the agenda in this increasingly vibrant field of research.

The human species is largely defined by its use of spoken language, so integral is speech communication to behavior and social interaction. Despite its importance in everyday life, comparatively little is known about the auditory mechanisms that underlie the ability to understand language. The current volume examines the perception and processing of speech from the perspective of the hearing system. The chapters in this book describe a comprehensive set of approaches to the scientific study of speech and hearing, ranging from anatomy and physiology, to psychophysics and perception, and computational modeling. The auditory basis of speech is examined within a biological and an evolutionary context, and its relevance to applied domains such as communication disorders and speech technology discussed in detail. This volume will be of interest to scientists, engineers, and clinicians whose professional work pertains to any aspect of spoken language or hearing science.

This book has its unique value as the pioneer study on the regional variants of Mandarin by experimental phonetics methods, sociophonetic methods, and AI assisted big data methods. Dialectal Mandarins are commonly well-recognized variations for standards Mandarin that have regional characteristics. This book is divided into four parts. The first part introduces Chinese, Chinese dialects, and Mandarin tones. In part two, the book makes a comprehensive and systematic comparison among Beijing Mandarin, Shanghai Mandarin, and Guangzhou Mandarin as the three major Mandarin variants by both the experimental phonetic methods and by using deep learning method. In the deep learning chapter, this book explores whether deep learning can recognize regional dialects patterns from the large amounts of data, and whether it can successfully identify the tonal system of each region’s dialects. The experimental results show that deep learning performs perfectly well in regional dialect recognition and tonal system learning. Liu Yuxuan, a student from USST, provided important technical support for the deep learning experiment. The third part further deepens the research perspective, and studies the geographically close subregional Mandarin. This part involves both acoustic research and perceptual research on three geographically close subregional dialects of Mandarin. The last part is a report on two experiments investigating dialectal experience’s role in predicting listeners’ subjective depiction on both non-categorical and categorical tonal variants of the official language, Putonghua. The dialectal resources recorded in this book are also valuable. The book is supposed to contribute to new progress in academic study on language variation, language evolution, experimental phonetics methods, as well as AI programming.

The clear and easy way to get a handle on the science of speech The science of how people produce and perceive speech, phonetics has an array of real-world applications, from helping engineers create an authentic sounding Irish or Canadian accent for a GPS voice, to assisting forensics investigators identifying the person whose voice was caught on tape, to helping a film actor make the transition to the stage. Phonetics is a required course among students of speech pathology and linguistics, and it's a popular elective among students of telecommunications and forensics. The first popular guide to this fascinating discipline, Phonetics For Dummies is an excellent overview of the field for students enrolled in introductory phonetics courses and an ideal introduction for anyone with an interest in the field. Bonus instructional videos, video quizzes, and other content available online for download on the dummies.com product page for this book.
