Computers that talk and listen: Man-machine communication by voice
James L. Flanagan · Proceedings of the IEEE · 1976
Computer techniques now emerging in the laboratory promise new capabilities for voice communication between man and machine. Three modes of interaction are of special interest: computer voice readout of stored information, automatic verification of a caller's identity by means of his voice signal, and automatic recognition of spoken commands. Applications extend to: voice-directed installation of telephone equipment, authentication by voice of a credit customer or of an individual requesting readout of privileged information, and voice-controlled services such as repertory dialing or automatic booking of travel reservations.
