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 2010-03-23 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the 15th International Symposium on Hearing (ISH), which was held at the Hotel Regio, Santa Marta de Tormes, Salamanca, Spain, between 1st and 5th June 2009. Since its inception in 1969, this Symposium has been a forum of excellence for debating the neurophysiological basis of auditory perception, with computational models as tools to test and unify physiological and perceptual theories. Every paper in this symposium includes two of the following: auditory physiology, psychoph- ics or modeling. The topics range from cochlear physiology to auditory attention and learning. While the symposium is always hosted by European countries, p- ticipants come from all over the world and are among the leaders in their fields. The result is an outstanding symposium, which has been described by some as a “world summit of auditory research. ” The current volume has a bottom-up structure from “simpler” physiological to more “complex” perceptual phenomena and follows the order of presentations at the meeting. Parts I to III are dedicated to information processing in the peripheral au- tory system and its implications for auditory masking, spectral processing, and c- ing. Part IV focuses on the physiological bases of pitch and timbre perception. Part V is dedicated to binaural hearing. Parts VI and VII cover recent advances in und- standing speech processing and perception and auditory scene analysis. Part VIII focuses on the neurophysiological bases of novelty detection, attention, and learning.

Download or read book The effect of hearing loss on neural processing written by Jonathan E. Peelle and published by Frontiers Media SA. This book was released on 2015-06-03 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient auditory processing requires the rapid integration of transient sensory inputs. This is exemplified in human speech perception, in which long stretches of a complex acoustic signal are typically processed accurately and essentially in real-time. Spoken language thus presents listeners’ auditory systems with a considerable challenge even when acoustic input is clear. However, auditory processing ability is frequently compromised due to congenital or acquired hearing loss, or altered through background noise or assistive devices such as cochlear implants. How does loss of sensory fidelity impact neural processing, efficiency, and health? How does this ultimately influence behavior? This Research Topic explores the neural consequences of hearing loss, including basic processing carried out in the auditory periphery, computations in subcortical nuclei and primary auditory cortex, and higher-level cognitive processes such as those involved in human speech perception. By pulling together data from a variety of disciplines and perspectives, we gain a more complete picture of the acute and chronic consequences of hearing loss for neural functioning.

This book was released on 1980 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing literature suggests that the hearing mechanism deals with incoming speech material by filtering the signals into a series of frequency bands. The width of these bands has been referred to as the critical band that is the perceptual frequency bandwidth observed in a variety of psychoacoustic contexts. Digital processing techniques have been developed for altering available recorded speech materials so that the frequency resolution available in the resultant stimuli may be controlled. Tapes have been produced wherein the frequency bandwidth resolution is limited to no better than one critical band and these tapes have been used in intelligibility testing. Some existing research indicates that the critical band is significantly widened in many individuals with sensorineural hearing loss of cochlear etiology. The digital processing routines described above were also used in developing tape recorded materials with bandwidth resolution limits considerably wider than the normal critical band. The bandwidths chosen for this stage of the digital processing were based on empirical observations of the critical band of sensorineural hearing impaired patients. These recordings were also used in intelligibility testing with normal listeners. Implications of these studies for the clinical measurement of speech intelligibility will be discussed. (Author).

Download or read book Speech Intelligibility Estimation Via Neural Networks written by Stephen Knight and published by . This book was released on 1990 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Current methods of speech intelligibility estimation rely on the subjective judgements of trained listeners. Accurate and unbiased intelligibility estimates have a number of procedural and/or methodological constraints including the necessity for large pools of listeners and a wide variety of stimulus materials. Recent research findings however, have shown a strong relationship between speech intelligibility estimates and selected acoustic speech parameters which appear to determine the intelligibility of speech. These findings suggest that such acoustic speech parameters could be used to derive computer-based speech intelligibility estimation, obviating the procedural and methodological constraints typically associated with such estimates. The relationship between speech intelligibility estimates and acoustic speech parameters is complex and nonlinear in nature. Artificial neural networks have proven in general speech recognition that they are capable of dealing with complex and unspecified nonlinear relationships. The purpose of this study was to explore the possibility of using artificial neural networks to make speech intelligibility estimates. Sixty hearing-impaired speakers, whose measured speech intelligibility ranged from 0 to 99%, were used as subjects in this study. In addition to measuring speech intelligibility, the speech of these subjects was digitally analyzed to obtain 6 acoustic speech parameters that have been found to critically differentiate English phonemes. The subjects were divided into two sub-groups. One of the subgroups was used to train a variety of back-propagation neural networks and the other was used to test the ability of the neural networks to make accurate speaker-independent speech intelligibility estimates. The artificial neural network that seemed to be the most efficatious for making speaker-independent speech intelligibility estimates employed a bipolar squash function and scaled values of the speech parameters. Compared to listener judgements the overall accuracy of the network's speech intelligibility estimates was a respectable 83%. These findings suggest that with expanded subject populations and more acoustic speech parameters it might be possible to create a practical computer based tool capable of objectively determining speech intelligibility."--Abstract.
