The Use of Speech for Man-Computer Communication.

摘要

The report investigates the intrisic characteristics and associated attractive features and problem areas of speech as a man-computer communication channel. Speech is independent of the manual and visual channels normally used for communicating with computers;it may permit simultaneous communication with both men and machines,and it can be used while the speaker is in motion,behind obstructions,and in total darkness. Any telephone instrument can become a computer terminal. Effective techniques for automatic speech recognition by computers are lacking. In a few years the results of current efforts in speech understanding research should make spoken communication with computers technically and economically feasible. The report discusses the general characteristics of man-computer tasks and interaction and the requirements these place on the application of speech understanding systems. (Author)
