2054	 On the Feasibility of Voice Input to an On-line Computer Processing System	 An on-line digital computer processing system is considered in which an ordinary telephone is the complete terminal device input to the computer being provided as a sequence of spoken words and output to the user being audio responses from the machine. The feasibility of implementing such a system with a FORTRAN-like algebraic compiler as the object processor is considered. Details of a specific word recognition program are given. This technique depends on three simplifying restrictions namely a small vocabulary set known speakers and a moment of silence between each input word. Experimental results are presented giving error rates for different experimental conditions as well as the machine resources required to accommodate several users at a time. The results show that at this time it is both economically and logically feasible to handle at least users at a time with an IBM computer. speech recognition word recognition pattern-matching pattern recognition time-sharing remote access voice input speech input telephone input output acoustic signal spoken-word input talking to computers man-machine interaction
