Book Description
This book interconnects two essential disciplines to study the perception of speech: Neuroscience and Quality of Experience, which to date have rarely been used together for the purposes of research on speech quality perception. In five key experiments, the book demonstrates the application of standard clinical methods in neurophysiology on the one hand and of methods used in fields of research concerned with speech quality perception on the other. Using this combination, the book shows that speech stimuli with different lengths and different quality impairments are accompanied by physiological reactions related to quality variations, e.g., a positive peak in an event-related potential. Furthermore, it demonstrates that – in most cases – quality impairment intensity has an impact on the intensity of physiological reactions.

Neural Correlates of Quality During Perception of Audiovisual Stimuli
Author: Sebastian Arndt
Publisher: Springer
ISBN: 9811002487
Category : Technology & Engineering
Languages : en
Pages : 96
Book Description
This book presents a new approach to examining the perceived quality of audiovisual sequences. It uses electroencephalography (EEG) to explain in detail how user quality judgments are formed within a test participant, and what the physiological implications might be when subjects are exposed to lower quality media. The book redefines the experimental paradigms of using EEG in the area of quality assessment so that they better suit the requirements of standard subjective quality testing, and presents experimental protocols and stimuli that have been adjusted accordingly.

Human Information Processing in Speech Quality Assessment
Author: Stefan Uhrig
Publisher: Springer Nature
ISBN: 303071389X
Category : Technology & Engineering
Languages : en
Pages : 169
Book Description
This book provides a new multi-method, process-oriented approach towards speech quality assessment, which allows readers to examine the influence of speech transmission quality on a variety of perceptual and cognitive processes in human listeners. Fundamental concepts and methodologies surrounding the topic of process-oriented quality assessment are introduced and discussed. The book further describes a functional process model of human quality perception, which theoretically integrates results obtained in three experimental studies. This book’s conceptual ideas, empirical findings, and theoretical interpretations should be of particular interest to researchers working in the fields of Quality and Usability Engineering, Audio Engineering, Psychoacoustics, Audiology, and Psychophysiology.

Dynamic Neural Correlates of Perceiving and Imagining Speech
Author: Siyi Deng
Publisher:
ISBN: 9781124420301
Category :
Languages : en
Pages : 97
Book Description
Recent studies have suggested that speech perception is processed by distinct brain networks, and correlated neural signals generated by these networks can be identified from brain electromagnetic recordings such as EEG. We studied the dynamic property of 40-Hz gamma band steady-state auditory responses evoked by speech and non-speech stimuli, and found that these two categories of signals are processed differentially over the left and right auditory cortex. We applied an envelope-based Hilbert-Huang decomposition of the data, and extracted signals from a functional network that is only correlated with speech stimuli. We believe these are evidences that speech signals are preferentially processed at a longer (syllabic) time scales than that of non-speech (phonetic). In a separate study, the envelope correlated neural signals have been used to successfully classify the perceived and imagined syllabic rhythms from EEG. We then developed a new method of geometrically accurate spline surface Laplacian (SSL) to improve the spatial resolution of EEG and to estimate the radial current source density on the inner skull surface. Numerical simulations and real EEG data have shown that the new method is more accurate than traditional spherical SSL by incorporating the surface curvature information (manuscript submitted). In a third experiment we recorded EEG when subjects were asked to listen or imagine a small set of selected sentences. We apply a fast wavelet transform technique to counter the lag and compression uncertainty of imagined speech, and apply the new SSL to the extracted signal to estimate the anatomical origin of the neural correlates.

The structure of the Workshop will feature a significant number of experts in language technologies and convergent areas. One objective will be the organization of forum sessions in order to review some of the current-trend research projects that are already addressing new methodological approaches and proposing solutions and innovative applications. A second major objective will be brainstorming sessions where representatives of the most innovative industrial sector in this area can present and describe the challenges and socio-economic needs of the present and immediate future. All researchers are invited to submit proposals that incorporate solid research and innovation ideas in the field of language technology and in connection with other convergent areas.

Different Representations of Neural Correlates of Spoken Language Comprehension in Local and Global Brain Activation Patterns
Author: Annika Urbschat
Publisher:
ISBN:
Category :
Languages : en
Pages :
Book Description
In this thesis spoken language comprehension models are evaluated based on different analysis methods for an auditory fMRI study. It aimed to distinguish between neural correlates of spoken language comprehension and the perception of speech-like signals, holding the acoustic properties of speech but without any meaningful content. The results are based on a novel approach for the evaluation of searchlight classification results. With multivariate pattern analyses, specific local brain activation patterns for spoken language comprehension could be identified in structures of the temporal, frontal, and parietal cortex as well as the cingulate cortex. A further network analysis based on the model of psycho-physiological interactions has shown a network between frontal- and parietal lobe areas and the cingulate cortex for the processing of valid speech and a network between temporo-parietal structures and the cingulate cortex for the processing of invalid speech.

Neural Control of Speech
Author: Frank H. Guenther
Publisher: MIT Press
ISBN: 0262336995
Category : Science
Languages : en
Pages : 426
Book Description
A comprehensive and unified account of the neural computations underlying speech production, offering a theoretical framework bridging the behavioral and the neurological literatures. In this book, Frank Guenther offers a comprehensive, unified account of the neural computations underlying speech production, with an emphasis on speech motor control rather than linguistic content. Guenther focuses on the brain mechanisms responsible for commanding the musculature of the vocal tract to produce articulations that result in an acoustic signal conveying a desired string of syllables. Guenther provides neuroanatomical and neurophysiological descriptions of the primary brain structures involved in speech production, looking particularly at the cerebral cortex and its interactions with the cerebellum and basal ganglia, using basic concepts of control theory (accompanied by nontechnical explanations) to explore the computations performed by these brain regions. Guenther offers a detailed theoretical framework to account for a broad range of both behavioral and neurological data on the production of speech. He discusses such topics as the goals of the neural controller of speech; neural mechanisms involved in producing both short and long utterances; and disorders of the speech system, including apraxia of speech and stuttering. Offering a bridge between the neurological and behavioral literatures on speech production, the book will be a valuable resource for researchers in both fields.
