Speech Analysis Synthesis and Perception

by James L Flanagan

Overview

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 computer 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.
