Book Description
The first edition of this book has enjoyed a gratifying existence. 1s sued in 1965, it found its intended place as a research reference and as a graduate-Ievel text. Research laboratories and universities reported broad use. Published reviews-some twenty-five in number-were universally kind. Subsequently the book was translated and published in Russian (Svyaz; Moscow, 1968) and Spanish (Gredos, S.A.; Madrid, 1972). Copies of the first edition have been exhausted for several years, but demand for the material continues. At the behest of the publisher, and with the encouragement of numerous colleagues, a second edition was begun in 1970. The aim was to retain the original format, but to expand the content, especially in the areas of digital communications and com puter techniques for speech signal processing. As before, the intended audience is the graduate-Ievel engineer and physicist, but the psycho physicist, phonetician, speech scientist and linguist should find material of interest.

Book Description
Naturalness in synthetic speech is one of the most intractable problems in information technology today. Although speech synthesis systems have improved considerably over the last 20 years, they rarely sound entirely like human speakers. Why is this so, and what can be done about it? * Prosodic processing must be rendered more varied and more appropriate to the speech situation * Timing, melodic control and the relationships between the various prosodic parameters need increased attention * Signal processing systems must be developed and perfected that are capable of generating more than just one voice from a database * A better understanding must be achieved of what distinguishes one voice from another, and of how speech styles differ between simply reading aloud numbers and sentences and their use in interactive speech * New evaluation methodologies should be developed to provide objective and subjective measurements of the intelligibility of the synthetic speech and the cognitive load imposed upon the listener by impoverished stimuli * Adequate text markup systems must be proposed and tested with multiple languages in real-world situations * Further research is required to integrate speech synthesis systems into larger natural-language processing systems Improvements in Speech Synthesis presents the latest research in the above areas. Contributors include speech synthesis specialists from 16 countries, with experience in the development of systems for 12 European languages. This volume emerges from a four-year European COST project focussed on "The Naturalness of Synthetic Speech", and will be a valuable text for everyone involved in speech synthesis.

Book Description
This dissertation describes a speech system based on a combination of physiological and psychoacoustic results which has been developed. The system contains a nonuniform Filter/Detector bank. A new relationship between Filter/Detectors and the Short-time Fourier Transform magnitude is derived, and a generalized version of the Short-Time Fourier Transform magnitude is used to implement the anlaysis system. The new relationship is also applied to a discussion of channel vocoders, spectrograms, the sliding Discrete Fourier Transform, average power spectrum estimation, and nonuniform bandwidth analysis. Next, a new synthesis approach is used to reconstruct signals form the magnitude data produced by the nonuniform analysis. Apart form an overall sign factor, the analysis/synthesis system achieves exact reconstruction in the absence of data modification. The ability of the system to reconstruct signals from modified data is also demonstrated. Suggestions for further research, including data reduction and automatic speech recognition applications, are given. Keywords include: Auditory modeling, short-time fourier transform, magnitude-only reconstruction, Power spectrum estimation, Perception, Filter banks, Speech recognition, Spectrograms, and Vocoders.

Book Description
For a machine to convert text into sounds that humans can understand as speech requires an enormous range of components, from abstract analysis of discourse structure to synthesis and modulation of the acoustic output. Work in the field is thus inherently interdisciplinary, involving linguistics, computer science, acoustics, and psychology. This collection of articles by leading researchers in each of the fields involved in text-to-speech synthesis provides a picture of recent work in laboratories throughout the world and of the problems and challenges that remain. By providing samples of synthesized speech as well as video demonstrations for several of the synthesizers discussed, the book will also allow the reader to judge what all the work adds up to -- that is, how good is the synthetic speech we can now produce? Topics covered include: Signal processing and source modeling Linguistic analysis Articulatory synthesis and visual speech Concatenative synthesis and automated segmentation Prosodic analysis of natural speech Synthesis of prosody Evaluation and perception Systems and applications.

Book Description
During recent years auditory research has advanced quite rapidly in the area of experimental psychology as well as in that of physiology. Scientists working in both areas have in cornrnon the study of the process in HEARING, yet different scientific areas always tend to diverge. A SYMPOSIUM ON PSY CHOPHYSICAL MODELS AND PHYSIOLOGICAL FACTS IN HEARING was or ganized for the exchange of information and to stimulate dis cussion between research workers in psychoacoustics, neurophy siology, anatomy, morphology and hydromechanics. The basic aim of holding this syrnposium was to halt the divergence and to initiate the kind of multi-disciplinary research that will be need ed to elucidate the hearing process as a whole. The present proceedings comprise the papers, which were circulated to the participants two months before the syrnposium and discussed during the syrnposium, together with some cornrnents and additional re marks. These cornrnents and rernarks do not, however, represent the full discussions but only the parts available in written form. We have arranged the material in five sections: I. Structure and Neurobiology of the Inner Ear II. Cochlear Mechanisms III. Auditory Frequency Analysis IV. Auditory Time Analysis V. Nonlinear Effects Within the limits of a syrnposium, none of these topics could be treated comprehensively; moreover, most of the papers concerned problems having several aspects.
