Book Description
First published in 1986. The important implications of speech variability for the future of speech related technology, in combination with the multifaceted debate about invariance among speech scientists, make this a most appropriate time to evaluate the state our knowledge in this area. On October 8-10, 1983 researchers from the fields of production, perception, acoustics, pathology, psychology, linguistics, language acquisition, synthesis and recognition met at a. symposium at M.I.T. on invariance and variability of speech processes. This volume is the Proceedings of the symposium. Each chapter of the book consists of a focus paper followed by some comments.

Book Description
The spectral and temporal characteristics of American English vowel and consonant sounds in a variety of phonetic contexts are examined and compared with data reported in the literature. Spectrograms and sampled spectra (obtained from an analog filter bank connected to a digital computer) were assembled for a number of monosyllabic and bisyllabic utterances generated by three talkers, and a variety of measurements were made from these displays. The characteristics examined include durations of vowels, durations of various phases of consonants in prestressed and poststressed positions and in clusters, spectra of vowels and diphthongs and their variation with time, spectra of consonants during constricted intervals, and time-variation of spectra during the release of consonants. The aim of the study is not to present an exhaustive acoustic-phonetic description of American English speech sounds but rather to indicate the kinds of acoustic properties that need to be utilized in schemes for machine recognition of speech.

Book Description
Contemporary Issues in Experimental Phonetics provides comprehensive coverage of a number of research topics on experimental phonetics. This book is divided into four parts. Part I describes the instrumentation systems employed in the study of speech acoustics and speech physiology. The models, aerodynamic principles, and peripheral physiological mechanisms of speech production are discussed in Part II. Part III explains the problems in the specifications of the acoustic characteristics of speech sounds and suprasegmental features of speech. The speech perception process, speaker recognition, theories on the nature of the dichotic right ear advantage, and errors in auditory perception are elaborated in the last chapter. This text likewise covers the measurement of temporal processing in speech perception and interrelationship of speech, hearing, and language in an understanding of the total human communication process. This publication is valuable to speech and hearing scientists, speech pathologists, audiologists, psychologists, linguists, and graduate students researching on experimental phonetics.

Book Description
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.

Book Description
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.
