Book Description
The fundamental question in speech compression is that of determining the minimum information rate that must be maintained between speaker and listener in order to achieve a specified level of speech fidelity or quality. The problem in answering this question is that a measure of speech quality must first be defined. Any meaningful definition of speech quality clearly must consider the manner in which speech is processed by the listener. If the details of the signal processing in the auditory system were known, speech quality could be defined in terms of the sensitivity of the listener to distortions of signals within the auditory system. A study of the manner in which sounds are processed by the human auditory system was done to provide the basic information to define a measure of speech fideltiy. The mechanical or soundconducting parts of the auditory system are reasonably well understood and can be considered as linear systems in an engineering sense. The neural processing of the peripheral auditory system is only partly understood. Further experimental work is necessary. (Author).

Book Description
Market_Desc: Professionals in the fields of ASR and speaker recognition, speech bandwidth compression, speech analysis and synthesis, and music analysis and synthesis Special Features: · Provides a top-level summary of speech and music processing from a historical perspective.· Introduce brief and selected introduction, when necessary, to mathematical concepts such as difference equation or probability dense functions. About The Book: Speech and music are the most basic means of adult human communication. As technology advances and increasingly sophisticated tools become available to use with speech and music signals, scientists can study these sounds more effectively, and invent new ways of applying them for the benefit of humankind. This text includes coverage of the physiology and psychoacoustics of hearing as well as the results from research on pitch and speech perception, vocoding methods and information on many aspects of automatic speech recognition (ASR) systems. The authors have made use of their own research in these fields, as well as the methods and results of many other contributors.

Book Description
All natural auditory signals, including human speech and animal communication signals, are spectrally and temporally complex, that is, they contain multiple frequencies and their frequency composition, or spectrum, varies over time. The ability of hearers to identify and localize these signals depends on analysis of their spectral composition. For the overwhelming majority of human listeners spoken language is the major means of social communication, and this communication therefore depends on spectral analysis. Spectral analysis begins in the cochlea, but is then elaborated at various stages along the auditory pathways in the brain that lead from the cochlea to the cerebral cortex. The broad purpose of Auditory Spectral Processing is to provide a comprehensive account of the way in which spectral information is processed in the brain and the way in which this information is used by listeners to identify and localize sounds. Examines spectral processing mechanisms at different levels along the auditory neuraxis, from the cochlear nucleus to the cortex Reviews in detail psychophysical and neurophysiological evidence on the way in which spectral information is processed within and across frequency channels Presents information on the nature of the spectral information required for speech and music perception Examines a series of issues that relate to the role of spectral analysis in higher order/cognitive aspects of hearing and in clinical and applied contexts

Book Description
This book contains the papers that were presented at the XIIIth International Symposium on Hearing (ISH), which was held in Dourdan, France, between August 24 and 29, 2003. From its first edition in 1969, the Symposium has had a distinguished tradition of bringing together auditory psychologists and physiologists. Hearing science now also includes computational modeling and brain imaging, and this is reflected in the papers collected. The rich interactions between participants during the meeting were yet another indication of the appositeness of the original idea to confront approaches around shared scientific issues. A total of 62 solicited papers are included, organized into 12 broad thematic areas ranging from cochlear signal processing to plasticity and perceptual learning. The themes follow the sessions and the chronological order of the paper presentations during the symposium. A notable feature of the ISH books is the transcription of the discussions between participants. A draft version of the book is circulated before the meeting, and all participants are invited to make written comments, before or during the presentations. This particularity is perhaps what makes the ISH book series so valuable as a truthful picture of the evolution of issues in hearing science. We tried to uphold this tradition, which was all the easier because of the excellent scientific content of the discussions.

Book Description
The auditory system of mammals is a highly developed sensory system that facilitates the analysis and the communication in complex acoustical scenes. For the analysis of incoming sounds, the auditory systems makes use of a large variety of physical signal properties that are processed within various mechanical and neural processing stages along the auditory pathway. The scope of this thesis was to investigate processing strategies that contribute to the outstanding performance of the auditory system to detect signals in complex acoustical scenes. Using methods from psychoacoustics and signal processing techniques, it has been shown that a combination of coherent intensity fluctuations in different frequency regions and interaural disparities are processed in a highly efficient way. With the application of a physical nonlinear and active model of the cochlea, the basis was provided for separating contributions of mechanical and neural processing stages to the analysis of complex acoustical scenes.
