<p>A description is given of a workstation with integrated graphical and voice I/O (input/output), to improve the man-machine interface (MMI) of the Airborne Warning and Control System (AWACS). Incremental prototype development is used to improve the MMI for AWACS. Operator tasks were analyzed to identify functions that would be better performed with voice I/O, and a 70-word vocabulary and corresponding grammar were developed for an ITT VRS-1280 speech recognizer. Responses for a DEC Talker speech synthesizer were also developed. The system architecture for integrating voice and graphical input in the AWACS interface prototype and its implementation are described and development issues are examined. Future developments are considered.</p>
