The starting point for the experimental investigation reported in this work is the observation that linguistic units (words, phonemes) do not have an acoustic invariance in the continuous speech. Moreover the a acoustic perception of a word or a phoneme depends on the context in which it is spoken. The experiments were designed to elucidate the interaction of word and context by examining the ways in which context affects the acoustic shape of a given word, as well as the role of context in word perception. The ultimate aim is to throw light on the mechanisms involved in the perception of continuous speech.

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.

Speech perception is dependent upon the ability to map the sensory features of a speech signal onto the perceptual features which make up language (i.e., phonemes). A great deal of research over the past six decades has focused on how variability across talkers influences speech processing. Listeners are required to normalize the acoustic variability across talkers by continuously updating the mapping from the acoustic signal to phonetic representations. As such, processing speech from multiple talkers is cognitively more demanding than listening to a single talker. This processing cost appears to reflect, in part, the influence of listeners’ expectations that speech is coming from multiple sources (talkers). It remains unclear whether talker normalization effects are present in individuals with autism spectrum disorder (ASD), given broad differences in social and sensory processing. The present study examined talker normalization and effects of talker expectation in adolescents with ASD and typical development. Participants were asked to respond to target words embedded in a stream of speech; the pitch of the talkers (F0) varied in half of trials. Furthermore, half of participants were told that this variability was due to fluctuations in a single talker’s speech, while the other half were told that the speech was variable because it was produced by two talkers. Results indicated that participants with ASD were significantly slower to respond under conditions of acoustic variability, while typically developing participants were not. Furthermore, the degree to which participants with ASD were influenced by the variability was significantly correlated with parent-reported sensory atypicality. This relationship was not moderated by ASD symptom severity. Neither diagnostic group was influenced by the manipulation of expectations. Overall, these results suggest that sensory differences present in ASD may account in part for communication difficulties.

Auditory Analysis and Perception of Speech documents the proceedings of a symposium on Auditory Analysis and Perception of Speech co-sponsored by the Academy of Sciences of the USSR and the Swedish Academy of Engineering Sciences, held in Leningrad, August 21-24, 1973. The purpose of the meeting was to advance the theory of speech perception in relation to auditory theory and speech signal models with some outlooks into the problem of automatic speech recognition. The book contains papers that were presented during the last three of the five sessions held. Session III on vowel perception includes studies on the variability of the code in connected speech; an auditory model of the perception of quasistationary vowels; and vowel processing at higher levels of the brain. Session IV on consonant perception includes papers that cover topics such as property detection, auditory segmentation, and consonant perception. Session V, which focuses on the prosodic features of speech, includes studies on temporal regularities of spoken Swedish; internal, auditory representation of syllable nucleus durations; and the factors that determine the timing of speech utterances.

Roughly defined as any property other than pitch, duration, and loudness that allows two sounds to be distinguished, timbre is a foundational aspect of hearing. The remarkable ability of humans to recognize sound sources and events (e.g., glass breaking, a friend’s voice, a tone from a piano) stems primarily from a capacity to perceive and process differences in the timbre of sounds. Timbre raises many important issues in psychology and the cognitive sciences, musical acoustics, speech processing, medical engineering, and artificial intelligence. Current research on timbre perception unfolds along three main fronts: On the one hand, researchers explore the principal perceptual processes that orchestrate timbre processing, such as the structure of its perceptual representation, sound categorization and recognition, memory for timbre, and its ability to elicit rich semantic associations, as well as the underlying neural mechanisms. On the other hand, timbre is studied as part of specific scenarios, including the perception of the human voice, as a structuring force in music, as perceived with cochlear implants, and through its role in affecting sound quality and sound design. Finally, computational acoustic models are sought through prediction of psychophysical data, physiologically inspired representations, and audio analysis-synthesis techniques. Along these three scientific fronts, significant breakthroughs have been achieved during the last decade. This volume will be the first book dedicated to a comprehensive and authoritative presentation of timbre perception and cognition research and the acoustic modeling of timbre. The volume will serve as a natural complement to the SHAR volumes on the basic auditory parameters of Pitch edited by Plack, Oxenham, Popper, and Fay, and Loudness by Florentine, Popper, and Fay. Moreover, through the integration of complementary scientific methods ranging from signal processing to brain imaging, the book has the potential to leverage new interdisciplinary synergies in hearing science. For these reasons, the volume will be exceptionally valuable to various subfields of hearing science, including cognitive auditory neuroscience, psychoacoustics, music perception and cognition, but may even exert significant influence on fields such as musical acoustics, music information retrieval, and acoustic signal processing. It is expected that the volume will have broad appeal to psychologists, neuroscientists, and acousticians involved in research on auditory perception and cognition. Specifically, this book will have a strong impact on hearing researchers with interest in timbre and will serve as the key publication and up-to-date reference on timbre for graduate students, postdoctoral researchers, as well as established scholars.

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.
