Available in PDF, EPUB and Kindle. Book excerpt: Automatic speech recognition (ASR) is one of the most important research areas in the field of speech technology and research. It is also known as the recognition of speech by a machine or, by some artificial intelligence. However, in spite of focused research in this field for the past several decades, robust speech recognition with high reliability has not been achieved as it degrades in presence of speaker variabilities, channel mismatch condi- tions, and in noisy environments. The superb ability of the human auditory system has motivated researchers to include features of human perception in the speech recognition process. This dissertation investigates the roles of perceptual features of human hearing in automatic speech recognition in clean and noisy environments. Methods of simplified synaptic adaptation and two-tone suppression by companding are introduced by temporal processing of speech using a zero-crossing algorithm. It is observed that a high frequency enhancement technique such as synaptic adaptation performs better in stationary Gaussian white noise, whereas a low frequency enhancement technique such as the two-tone sup- pression performs better in non-Gaussian non-stationary noise types. The effects of static compression on ASR parametrization are investigated as observed in the psychoacoustic input/output (I/O) perception curves. A method of frequency dependent asymmetric compression technique, that is, higher compression in the higher frequency regions than the lower frequency regions, is proposed. By asymmetric compression, degradation of the spectral contrast of the low frequency formants due to the added compression is avoided. A novel feature extraction method for ASR based on the auditory processing in the cochlear nucleus is presented. The processings for synchrony detection, average discharge (mean rate) processing and the two tone suppression are segregated and processed separately at the feature extraction level according to the differential processing scheme as observed in the AVCN, PVCN and the DCN, respectively, of the cochlear nucleus. It is further observed that improved ASR performances can be achieved by separating the synchrony detection from the synaptic processing. A time-frequency perceptual spectral subtraction method based on several psychoacoustic properties of human audition is developed and evaluated by an ASR front-end. An auditory masking threshold is determined based on these psychoacoustic e®ects. It is observed that in speech recognition applications, spec- tral subtraction utilizing psychoacoustics may be used for improved performance in noisy conditions. The performance may be further improved if masking of noise by the tonal components is augmented by spectral subtraction in the masked region.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding Language: An Information-Processing Analysis of Speech Perception, Reading, and Psycholinguistics focuses on the progress of approaches, principles, and practices involved in speech perception, reading, and psycholinguistics. The selection first offers information on language and information processing, articulatory and acoustic characteristics of speech sounds, and acoustic features in speech perception. Discussions focus on vowel and consonant recognition, production of speech sounds, general acoustic properties and occurrence of speech sounds, vowel phonemes of English, and information, auditory, and visual information processing. The text then examines preperceptual images, processing time, and perceptual units in speech perception, theories of perception, and visual features, preperceptual storage, and processing time in reading. Topics include processing time, visual features, summary of information-processing analysis of speech perception, role of linguistic structure in model building, and preperceptual images and processing time. The manuscript takes a look at an analysis of psychological studies of grammar, word and phrase recognition in speech processing, and linguistic theory and information processing, including psychological function of certain transformation rules, psychological reality of constituent structure, and linguistics and psychology. The selection is a vital source of data for researchers interested in speech perception, reading, and psycholinguistics.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The idea that speech is a dynamic process is a tautology: whether from the standpoint of the talker, the listener, or the engineer, speech is an action, a sound, or a signal continuously changing in time. Yet, because phonetics and speech science are offspring of classical phonology, speech has been viewed as a sequence of discrete events-positions of the articulatory apparatus, waveform segments, and phonemes. Although this perspective has been mockingly referred to as "beads on a string", from the time of Henry Sweet's 19th century treatise almost up to our days specialists of speech science and speech technology have continued to conceptualize the speech signal as a sequence of static states interleaved with transitional elements reflecting the quasi-continuous nature of vocal production. This book, a collection of papers of which each looks at speech as a dynamic process and highlights one of its particularities, is dedicated to the memory of Ludmilla Andreevna Chistovich. At the outset, it was planned to be a Chistovich festschrift but, sadly, she passed away a few months before the book went to press. The 24 chapters of this volume testify to the enormous influence that she and her colleagues have had over the four decades since the publication of their 1965 monograph.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of Speech Recognition explores the mechanisms underlying speech recognition. Topics covered include the auditory system, speech production, auditory psychophysics, speech synthesis and analysis, vowel and consonant recognition, and perception of prosodic features and of distorted speech. Automatic speech recognition and models of speech recognition are also given consideration. This volume consists of 11 chapters and begins with an overview of speech recognition, communication, and production. More specifically, it examines the way in which the organs of the vocal apparatus are employed to transform a message consisting of a string of linguistic units, such as words or phonemes, into a wave of continuous sounds which are recognized as speech. The auditory system and its parts are then described, from the ears to the organ of Corti and nerve cells. The chapters that follow focus on the behavior of the hearing system, the various techniques of analyzing speech sounds, and speech synthesizers such as vocoders. The mechanisms underlying the recognition of vowels and consonants are also described, along with the physical parameters of the speech wave which signal the prosody of an utterance, the effects of distortions in the speech wave on speech perception, and tools used in automatic speech recognition. The book concludes with an evaluation of models of speech recognition. This book will be of interest to phoneticians, linguists, physiologists, psychologists, and physicists.

Available in PDF, EPUB and Kindle. Book excerpt: When Speech and Audio Signal Processing published in 1999, it stood out from its competition in its breadth of coverage and its accessible, intutiont-based style. This book was aimed at individual students and engineers excited about the broad span of audio processing and curious to understand the available techniques. Since then, with the advent of the iPod in 2001, the field of digital audio and music has exploded, leading to a much greater interest in the technical aspects of audio processing. This Second Edition will update and revise the original book to augment it with new material describing both the enabling technologies of digital music distribution (most significantly the MP3) and a range of exciting new research areas in automatic music content processing (such as automatic transcription, music similarity, etc.) that have emerged in the past five years, driven by the digital music revolution. New chapter topics include: Psychoacoustic Audio Coding, describing MP3 and related audio coding schemes based on psychoacoustic masking of quantization noise Music Transcription, including automatically deriving notes, beats, and chords from music signals. Music Information Retrieval, primarily focusing on audio-based genre classification, artist/style identification, and similarity estimation. Audio Source Separation, including multi-microphone beamforming, blind source separation, and the perception-inspired techniques usually referred to as Computational Auditory Scene Analysis (CASA).

Available in PDF, EPUB and Kindle. Book excerpt: A series of experiments that treated auditory perception in humans was conducted. These investigations were at the information processing level and were structured to test hypotheses of sensory filtering, feature detection, the organization of a matching system, and the possible role of the motor theory of speech perception in the perception of speech. The studies include multidimensional scaling investigations, tests of the motor theory of speech perception, studies on subphonemic or distinctive features of speech, and experiments on the perceived order of short auditory events. The results of these studies support the idea that the auditory system operates as a feature detector and that these features may relate to articulatory properties of the vocal tract. Further evidence of features was found in short-term recall of phonemes where the error responses indicated that features were retained where phonomes were forgotten. Investigations of perceived order of short auditory events indicate that similar stimuli are grouped together by the auditory system and, in some instances, are heard in a perceptual order that is different from the actual physical order of the stimuli.
