Present auto-answer devices used for disseminating information have two general inefficiencies. First, the rate of information transmission is slow relative to the rate at which listeners can receive and comprehend speech information. Second, a caller may be forced to listen to a significant amount of material in which he has little or no interest in order to get to hear the information which prompted his call. This thesis describes the design, construction, and operation of a telephone accessible, user-interactive, microprocessor controlled information dissemination system. Through the use of speech compression and user interaction, this system attempts to improve these two deficiencies. Speech compression allows recorded messages to be played back at up to twice their original rate without significant loss in intelligibility. User interaction allows the caller to select only messages in which he has an interest. Interaction consists of the user either dialing or pressing a digit to select the secondary tape of his choice . A low cost, microprocessor- based YES/NO detector was also developed to complement the system. The YES/NO detector allows a more natural user interaction with the system.
