    Five approaches that can be used to control and simplify the speech recognition task are examined. They entail the use of isolated words, speaker-dependent systems, limited vocabulary size, a tightly constrained grammar, and quiet and controlled environmental conditions. The five components of a speech recognition system are described: a speech capture device, a digital signal processing module, p... View full abstract»

    The use of speaker-independent speech recognition in the development of Northern Telecom's automated alternate billing service (AABS) for collect calls, third-number-billed calls, and calling-card-billed calls is discussed. The AABS system automates a collect call by recording the calling party's name, placing a call to the called party, playing back the calling party's name to the called party, i...

    Some necessary background in speech recognition and window systems is given, with an analysis of how they might be combined. Xspeak, a navigation application, and its operation and a field study of its use are described. With Xspeak, window navigation tasks usually performed with a mouse can be controlled by voice. An improved version, Xspeak II, which incorporates a language for translating spoke... View full abstract»

    A description is given of a workstation with integrated graphical and voice I/O (input/output), to improve the man-machine interface (MMI) of the Airborne Warning and Control System (AWACS). Incremental prototype development is used to improve the MMI for AWACS. Operator tasks were analyzed to identify functions that would be better performed with voice I/O, and a 70-word vocabulary and correspond... View full abstract»
