Number Theory in Science and Communication is an introduction for non-mathematicians. The book stresses intuitive understanding rather than abstract theory and highlights important concepts such as continued fractions, the golden ratio, quadratic residues and Chinese remainders, trapdoor functions, pseudoprimes and primituve elements. Their applications to problems in the real world is one of the main themes of the book. This third edition is augmented by recent advances in primes in progressions, twin primes, prime triplets, prime quadruplets and quintruplets, factoring with elliptic curves, quantum factoring, Golomb rulers and "baroque" integers.

Focusing on advancements in speech research, this volume includes a new chapter by Holger Quast that explores speech dialogue systems and natural language processing. It highlights applications such as dictation software, voice dialing, and automated services in various sectors, emphasizing their significance for accessibility. The chapter offers an overview of essential linguistic concepts, covering both symbolic and statistical methodologies, and details proven language processing tools. Additionally, it introduces the fundamental components of modern dialogue systems.

New material 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 focuses on speech and audio compression for mobile communication and the Internet. The importance of subjective quality criteria is stressed. The book also contains introductions to human monaural and binaural hearing, and the basic concepts of signal analysis. Beyond speech processing, this revised and extended new edition of Computer Speech gives an overview of natural language technology and presents the nuts and bolts of state-of-the-art speech dialogue systems.

„Das umfangreiche Inahltsverzeichnis am Anfang des Buches vermittelt einen aussagekräftigen Ausblick auf die zahlreichen Gebiete der Wissenschaft, die man beim Lesen durchstreifen soll. Selbst, wenn man daraufhin die Lektüre mit hohen Erwartungen beginnt, ist kaum mit einer Enttäuschung zu rechnen: Die Vielfalt der behandelten Themen und aufgezeigten Querverbindungen zwischen unterschiedlichen Zweigen der Wissenschaft ist schwer zu überbieten, und von den leicht verständlichen, originell verfaßten Texten ist amn schnell vereinnahmt.“ „Bemerkenswert sind aber vor allem die vielen einfachen Gedankenexperimente (...)“ „Eine weitere Besonderheit des Buches ist das Einbeziehen von Gegenständen der Psychologie (...)“ NATURWISSENSCHAFTEN
