Download or read book Voice Communication Between Humans and Machines written by for the National Academy of Sciences and published by National Academies Press. This book was released on 1994-02-01 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science fiction has long been populated with conversational computers and robots. Now, speech synthesis and recognition have matured to where a wide range of real-world applicationsâ€"from serving people with disabilities to boosting the nation's competitivenessâ€"are within our grasp. Voice Communication Between Humans and Machines takes the first interdisciplinary look at what we know about voice processing, where our technologies stand, and what the future may hold for this fascinating field. The volume integrates theoretical, technical, and practical views from world-class experts at leading research centers around the world, reporting on the scientific bases behind human-machine voice communication, the state of the art in computerization, and progress in user friendliness. It offers an up-to-date treatment of technological progress in key areas: speech synthesis, speech recognition, and natural language understanding. The book also explores the emergence of the voice processing industry and specific opportunities in telecommunications and other businesses, in military and government operations, and in assistance for the disabled. It outlines, as well, practical issues and research questions that must be resolved if machines are to become fellow problem-solvers along with humans. Voice Communication Between Humans and Machines provides a comprehensive understanding of the field of voice processing for engineers, researchers, and business executives, as well as speech and hearing specialists, advocates for people with disabilities, faculty and students, and interested individuals.

Available in PDF, EPUB and Kindle. Book excerpt: Research in the area of packet voice over the past ten years has proven the value of packet technology for voice transmission. Continuing research in this area has led to the development of a packet satellite network for use as a testbed for packet voice telephone services. In order to allow a wide range of users to participate in the testing of this technology, ISI has developed the Switched Telephone Network Interface card to allow interconnection between the packet network and the commercial telephone system. This report describes the design of this device and the discusses the techniques used to implement functions such as sound/silence detection, echo suppression, and dialing. (Author).
