✦ Synopsis

A low-cost stand-alone voice-response system (DUVO) for biomedical applications is described. The system combines a touch-tone decoding input unit with a central microprocessor and taped and synthetic voice-generating devices. The inclusion of the microprocessor permits the DUVO unit to initiate and maintain contact with a larger central timeshared computer. It also makes it possible to format all input and output messages to the individual requirements of the central computer. Thus, the DUVO appears as a standard remote terminal to the central processor and requires no modification of the main computer system. The DUVO unit has been applied in a wide variety of medical applications where the input vocabulary is limited and hard-copy output is not required. Since any standard touchtone telephone can now serve as a computer terminal, a number of existing computer applications to medicine can now be made more universally available and cost effective.
