Available in PDF, EPUB and Kindle. Book excerpt: A recent study indicates that 20 million people in the United States have significant sensorineural hearing loss. Approximately 95% of those people have partial losses, with varying degrees of residual hearing. These percentages are similar in other developed countries. What changes in the function of the cochlea or inner ear cause such losses? What does the world sound like to the 19 million people with residual hearing? How should we transform sounds to correct for the hearing loss and maximize restoration of normal hearing? Answers to such questions require detailed models of the way that sounds are processed by the nervous system, both for listeners with normal hearing and for those with sensorineural hearing loss. This book contains chapters describing the work of 25 different research groups. A great deal of research in recent years has been aimed at obtaining a better physiological description of the altered processes that cause sensorineural hearing loss and a better understanding of transformations that occur in the perception of those sounds that are sufficiently intense that they can still be heard. Efforts to understand these changes in function have lead to a better understanding of normal function as well. This research has been based on rigorous mathematical models, computer simulations of mechanical and physiological processes, and signal processing simulations of the altered perceptual experience of listeners with sensorineural hearing loss. This book provides examples of all these approaches to modeling sensorineural hearing loss and a summary of the latest research in the field.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a microscopic model of human speech recognition (HSR), microscopic in a sense that first, the recognition of single phonemes rather than the recognition of whole sentences is modeled. Second, the particular spectro-temporal structure of speech is processed by an auditory model. This contrasts with other models of HSR, which usually use the spectral structure only. The model is capable of predicting phoneme recognition in normal-hearing (NH) listeners in noise along with important aspects of consonant recognition in quiet. Furthermore, this model is extended for the prediction of sentence recognition. The extension is capable of predicting speech recognition of NH and hearing-impaired (HI) listeners as accurately as a standard speech intelligibility model. Parameters reflecting the supra-threshold auditory processing are assessed in NH and HI listeners using psychoacoustical techniques such as forward masking and categorical loudness scaling. These supra-threshold auditory processing deficits are included in the model and the results show that implementing supra-threshold processing improves prediction accuracy. engl.

This book was released on 2006-05-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although speech is the primary behavioral medium by which humans communicate, its auditory basis is poorly understood, having profound implications on efforts to ameliorate the behavioral consequences of hearing impairment and on the development of robust algorithms for computer speech recognition. In this volume, the authors provide an up-to-date synthesis of recent research in the area of speech processing in the auditory system, bringing together a diverse range of scientists to present the subject from an interdisciplinary perspective. Of particular concern is the ability to understand speech in uncertain, potentially adverse acoustic environments, currently the bane of both hearing aid and speech recognition technology. There is increasing evidence that the perceptual stability characteristic of speech understanding is due, at least in part, to elegant transformations of the acoustic signal performed by auditory mechanisms. As a comprehensive review of speech's auditory basis, this book will interest physiologists, anatomists, psychologists, phoneticians, computer scientists, biomedical and electrical engineers, and clinicians.

This book was released on 2020 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study used a dual-task paradigm to describe how noise type may interact with aging and hearing loss to impact speech recognition and listening effort. Three noise types with varying degrees of spectral and/or temporal modulation were used: speech-shaped noise, speech-modulated noise, and three-talker babble. Subject groups included young normal-hearing listeners, older listeners with near-normal hearing, and older listeners with sensorineural hearing loss. An adaptive measure was used to compare the SNR at which 70% sentence recognition was achieved in each noise type, allowing an analysis of the effects of age and hearing loss on the ability to benefit from spectro-temporal glimpsing. A word recall task was implemented in a dual-task paradigm to compare listening effort, while matching overall performance across noise types and subject groups. Results showed no evidence to support the hypothesis that noise type influenced listening effort in any subject group. Results also showed that younger normal-hearing listeners were highly robust to the detrimental effects of noise, while older listeners experienced reduction in listening effort when context was available. Sensorineural hearing loss nullified this benefit from context. This study presented novel findings regarding the effect of noise type on listening effort while overall speech recognition performance was controlled for.

Available in PDF, EPUB and Kindle. Book excerpt: This research investigates the longstanding problem of understanding human speech perception. We aim to study speech perception and decode perceptual cues in speech by conducting psychoacoustic experiments on several subjects by presenting them with nonsense consonant-vowel (CV) syllables in various kinds of masking noise at di fferent signal-to-noise ratios (SNRs). Our research with a large number of normal hearing (NH) listeners shows that NH speech perception is deterministic and the error is essentially zero when the main perceptual feature (or event) of the utterance is audible. With the perceptual CV cues precisely known, one can predict how an average normal hearing (ANH) listener would behave in a certain type and degree of masking noise. The next major goal of the current research is to characterize hearing-impaired (HI) ears by using our knowledge of specific consonant speech cues in ANH ears, thus quantifying how the HI ears di ffer from ANH ears in their use of acoustic cues. Our analysis shows that HI ears may have poor temporal and/or frequency resolution, because of which they are unable to hear only a few consonants, yet they can hear the rest. We argue that it is necessary to measure this consonant dependence in order to design a more sensitive hearing aid fi tting technique, and no other clinical measure used currently (audiometry, average speech recognition scores, speech in noise tests) is useful in characterizing speech-loss, in HI ears. We measured 46 HI ears with our CV discrimination test using the current hearing aid amplifi cation technique NAL-R; the results show that though NAL-R improves the aver- age score, it degrades a few consonants under certain circumstances. This research also addresses the important issue of cochlear dead regions, which are places along the basilar membrane of the cochlea where the inner hair cells are degenerate. We propose a new method to diagnose dead regions based on comodulation masking release. This project extends our effort to achieve a fundamental insight into the nature of both ANH and HI speech perception, enabling the design of hearing aids that are functionally useful in high ambient noise and that help make audible the sounds that the HI ear could not hear previously, without aff ecting the sounds that they can hear.

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.
