Speech Analysis Synthesis and Perception

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.

Facts and Models in Hearing

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.
