The first edition having been sold out, gives me a welcome opportunity to augment this volume by some recent applications of speech research. A new chapter, by Holger Quast, treats speech dialogue systems and natural lan­ guage processing. Dictation programs for word processors, voice dialing for mobile phones, and dialogue systems for air travel reservations, automated banking, and translation over the telephone are at the forefront of human-machine inter­ faces. Spoken language dialogue systems are also invaluable for the physically handicapped. For researchers new to the field, the new chapter (pp. 67-106) provides an overview of fundamental linguistic concepts from phonetics, morphology, syntax, semantics and pragmatics, gramm ars and knowedge representation. Symbolic methodology, such as Norman Chomsky's traditional hierarchy of formal languages is layed out as are statistical approaches to analyze text. Proven tools of language processing are covered in detail, including finite­ state automata, Zipf's law, trees annd parsers. The second part of the new chapter introduces the building blocks of state-of-the-art dialogue systems.

"Beauty is the first test: there is no permanent place in the world for ugly mathematics. " - G. H. Hardy N umber theory has been considered since time immemorial to be the very paradigm of pure (some would say useless) mathematics. In fact, the Chinese characters for mathematics are Number Science. "Mathematics is the queen of sciences - and number theory is the queen of mathematics," according to Carl Friedrich Gauss, the lifelong Wunderkind, who hirnself enjoyed the epithet "Princeps Mathematicorum. " What could be more beautiful than a deep, satisfying relation between whole numbers. {One is almost tempted to call them wholesome numbersJ In fact, it is hard to come up with a more appropriate designation than their learned name: the integers - meaning the "untouched ones". How high they rank, in the realms of pure thought and aesthetics, above their lesser brethren: the real and complex number- whose first names virtually exude unsavory involvement with the complex realities of everyday life! Yet, as we shall see in this book, the theory of integers can provide totally unexpected answers to real-world problems. In fact, discrete mathematics is ta king on an ever more important role. If nothing else, the advent of the digital computer and digital communication has seen to that. But even earlier, in physics the emergence of quantum mechanics and discrete elementary particles put a premium on the methods and, indeed, the spirit of discrete mathematics.

Computer Speech is an introduction to multimedia speech applications and is suitable for nonspecialists. It treats such contemporary subjects as automatic speech recognition and speaker verification for banking by computer and privileged (medical, military, diplomatic) information and control access. The book also focusses on speech and audio compression for mobile communication and the Internet. The importance of subjective quality criteria is stressed. A brief history of speech research summarizes the development from the first talking machines in rococo Europe to modern x-ray methods of articulatory analysis. The book also contains introductions to human monaural and binaural hearing, and the basic concepts of signal analysis.
