This book was released on 2006 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that machines perform far worse than humans in recognizing speech and audio, especially in noisy environments. One method of addressing this issue of robustness is to study physiological models of the human auditory system and to adopt some of its characteristics in computers. As a first step in studying the potential benefits of an elaborate computational model of the primary auditory cortex (A1) in the central auditory system, we qualitatively and quantitatively validate the model under existing speech processing recognition methodology. Next, we develop new insights and ideas on how to interpret the model, and reveal some of the advantages of its dimension-expansion that may be potentially used to improve existing speech processing and recognition methods. This is done by statistically analyzing the neural responses to various classes of speech signals and forming empirical conjectures on how cognitive information is encoded in a category-dependent manner. We also establish a theoretical framework that shows how noise and signal can be separated in the dimension-expanded cortical space. Finally, we develop new feature selection and pattern recognition methods to exploit the category-dependent encoding of noise-robust cognitive information in the cortical response. Category-dependent features are proposed as features that "specialize" in discriminating specific sets of classes, and as a natural way of incorporating them into a Bayesian decision framework, we propose methods to construct hierarchical classifiers that perform decisions in a two-stage process. Phoneme classification tasks using the TIMIT speech database are performed to quantitatively validate all developments in this work, and the results encourage future work in exploiting high-dimensional data with category(or class)-dependent features for improved classification or detection.

Download or read book Auditory Analysis and Perception of Speech written by G Fant and published by Elsevier. This book was released on 2012-12-02 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Speech Analysis Based on a Model of the Auditory System written by Harvey E. Rhody and published by . This book was released on 1986 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a signal processing technique for speech signals based on a model of the processing done in the auditory system. It has been found that the click response of the auditory system is an exponential function. The spectrogram produced by a speech waveform that has been windowed by the same function possesses excellent resolution of both time and frequency parameters of the signal. It is expected that this analysis method will improve the discrimination of phonemic elements, and will prove useful in such applications as speech recognition and speech compression.

Download or read book Contrast Neutralization and Systems of Invariance written by Anna Mai and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speech is a highly-structured auditory signal that carries necessary and sufficient information for language comprehension among neurotypical, hearing populations. Speech perception, accordingly, involves the integration of both bottom-up auditory processing and top-down language knowledge. As explored in Chapter 1, however, while much is known about the brain's sensitivity to various acoustic and phonological manipulations, mechanistic transformative links between auditory sensation and linguistic perception remain poorly understood. This dissertation contributes three studies to the ongoing pursuit of links between auditory and linguistic processing of speech in the brain. Intracranial stereo electroencephalography (sEEG) was recorded while participants listened to conversational English speech, and for each study, different sets of analyses were performed to target different aspects of these links. Chapter 2 introduces a novel comparative technique for the isolation of phonological and morphological identity from the auditory speech signal. Through structured comparisons of the neural response to sounds in allophonic relationships with one another, sites that dissociate phonemic and morphological identity from acoustic similarity were identified. These results provide crucial evidence that the neural response to speech is sensitive to abstract sub-lexical structure. Chapter 3 provides general models to account for the unique contributions of categorical phonemic information and spectrographic information to the neural response. In lower frequency bands, phonemic category information explained a greater proportion of the neural response variance than spectrographic information. These results indicate that the explanatory value of phonemic category features in neural encoding models is not reducible to the surface spectrotemporal features that correlate with those categories. Chapter 4 proposes a model for the relationship between the speech stimulus and neural response that integrates both phonemic and spectrographic information. Inclusion of the stimulus covariance structure increased model accuracy only when categorical phonemic information was available, indicating that phoneme-related neural activity is likely mediated through the acoustic covariance structure of speech. Moreover, phonemic label information conferred no benefit to model fit when participants listened to speech in an unfamiliar language (Catalan). Together these studies show that neural responses associated with categorical phonemic information are language specific and irreducible to speech acoustics, and they scout a path towards mechanistic, transformative links between auditory sensation and language cognition.

Download or read book Perception and Production of Fluent Speech written by Ronald A. Cole and published by Routledge. This book was released on 2016-07-28 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1980, this title looks at the mental processes involved in producing and understanding spoken language. Although there had been several edited volumes on speech in the previous ten years, this volume was unique in that it deals exclusively with perception and production of fluent speech. The chapters in this volume, contributed to by distinguished scientists from psychology, linguistics and computer science, deal with such questions as: How are ideas encoded into sound? How does a speaker plan an utterance? How are words recognized? What is the role of knowledge in speech perception? In short, how do people communicate with each other using speech?
Download or read book Speech Analysis Synthesis and Perception written by James L. Flanagan and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has its origin in a letter. In November of 1959, the late Prof. Dr. WERNER MEYER-EpPLER wrote to me, asking if I would contribute to a series he was planning on Communication. His book " Grundlagen und Anwendungen der Informationstheorie" was to serve as the initial volume of the series. After protracted consideration, I agreed to undertake the job provided it could be done outside my regular duties at the Bell Telephone Laboratories. Shortly afterwards, I received additional responsibilities in my research organization, and felt that I could not conveniently pursue the manuscript. Consequently, except for the preparation of a detailed outline, the writing was delayed for about a year and a half. In the interim, Professor MEYER-EpPLER suffered a fatal illness, and Professors H. WOLTER and W. D. KEIDEL assumed the editorial re sponsibilities for the book series. The main body of this material was therefore written as a leisurc time project in the years 1962 and 1963. The complete draft of the manuscript was duplicated and circulated to colleagues in three parts during 1963. Valuable comments and criticisms were obtained, revisions made, and the manuscript submitted to the publisher in March of 1964. The mechanics of printing have filled the remaining time. If the reader finds merit in the work, it will be owing in great measure to the people with whom I have had the good fortune to be associated.
Download or read book Speech Recognition in Adverse Conditions written by Sven Mattys and published by Psychology Press. This book was released on 2013-12-19 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speech recognition in ‘adverse conditions’ has been a familiar area of research in computer science, engineering, and hearing sciences for several decades. In contrast, most psycholinguistic theories of speech recognition are built upon evidence gathered from tasks performed by healthy listeners on carefully recorded speech, in a quiet environment, and under conditions of undivided attention. Building upon the momentum initiated by the Psycholinguistic Approaches to Speech Recognition in Adverse Conditions workshop held in Bristol, UK, in 2010, the aim of this volume is to promote a multi-disciplinary, yet unified approach to the perceptual, cognitive, and neuro-physiological mechanisms underpinning the recognition of degraded speech, variable speech, speech experienced under cognitive load, and speech experienced by theoretically relevant populations. This collection opens with a review of the literature and a formal classification of adverse conditions. The research articles then highlight those adverse conditions with the greatest potential for constraining theory, showing that some speech phenomena often believed to be immutable can be affected by noise, surface variations, or attentional set in ways that will force researchers to rethink their theory. This volume is essential for those interested in speech recognition outside laboratory constraints.

Book excerpt: This paper reviews the psychophysical basis for auditory models and discusses their application to automatic speech recognition. First an overview of the human auditory system is presented, followed by a review of current knowledge gleaned from neurological and psychoacoustic experimentation. Next, a general framework describes established peripheral auditory models which are based on well-understood properties of the peripheral auditory system. This is followed by a discussion of current enhancements to that models to include nonlinearities and synchrony information as well as other higher auditory functions. Finally, the initial performance of auditory models in the task of speech recognition is examined and additional applications are mentioned. Keywords: Natural language, Speech processing. (kt).
