Conversant® 1 Voice System: Architecture and Applications
Robert J. Perdue, Eugene L. Rissanen · AT&T Technical Journal · 1986
A flexible and cost-effective system for introducing speech technology into the marketplace is described. The system answers telephone calls from lines and trunks and provides verbal prompts and information to the caller. The caller can request specific information and direct the transaction by using either touch-tone or voice input. Requested information is obtained either from a small data base on the system disk or from an external source. Other system functions include recognition of isolated words and connected digit strings, recording and encoding of phrases and announcements for playback during a transaction, and call transfer and origination. A special interpreted language for specifying the transaction dialog allows diverse applications of the system to be easily written and modified.
