SPEECH CODING

This paper is a camel.* Short of a book-length text (which, incidentally, one of us (NSJ) is writing), our task to discuss the field of digital speech coding is well-nigh impossible. Nevertheless, we have attempted to respond to this charge in a circumscribed, if not disjoint, way. Our hope here is to expose the reader to a selection of critical topics and current techniques in digital voice. Our choice is highly parochial-a collection of “islands”-and many good colleagues will feel slighted. We have tried to minimize the latter effect through extensive references. At the same time have concentrated on those topics with which we have first-hand familiarity and one which we can comment confidently. We hope the reader will appreciate this stance and make allowances for it. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
