    The two methods described for giving voices to computers recognize the importance of economical storage of speech information and extensive vocabularies, and consequently are based on principles of speech synthesis. The first, formant synthesis, generates connected speech from low-bit-rate representations of spoken words. The second, text synthesis, produces connected speech solely from printed En...

    The purpose of this article is to categorize the needs and desired features that a logic or system designer should consider when selecting a family of digital integrated circuits. The various major digital IC families are evaluated and compared with these needs in view. The intended results are that the reader will gain facility in IC technology, terminology, and usage in various areas of applicat... View full abstract»

    The transmission of electromagnetic energy through seawater is so heavily attenuated that it is necessary to turn to acoustic energy to transmit information over any appreciable range of ocean. In the sea, the absorption of acoustic energy is several orders of magnitude less than that of electromagnetic waves. Still, this absorption constitutes a limitation on the bandwidth of the communication li... View full abstract»

    The idea of coding the human voice into digital pulses was conceived more than three decades ago; exploitation had to await the ushering in of the transistor era. Since then, coding systems gradually have improved. One of the latest and most efficient schemes is delta modulation. Compared with earlier analog-to-digital-pulse conversion systems, an increase in the voice-handling capacity of telepho... View full abstract»

  • Planning the coordination of ground transport

    Publication Year: 1970, Page(s):79 - 86

    Proper coordination in the design of a transportation system requires consideration of general land use in the area served, and indeed of the entire sociological and ecological fabric of society. Moreover, the designer must help weave this fabric while it is being used. A possible starting place for a transportation study, and some would argue the only starting place, is an overall regional plan. ... View full abstract»
