Voice Technology Design Guides for Navy Training Systems

摘要

This project was directed toward gathering information about applications of automated speech technology (AST) and formulating design guidelines for the use of AST in Navy training systems. Information was obtained from three major sources: a review of the scientific and technical literature; a review of the documentation of prior Navy AST training system prototypes; and interviews with key scientists. Design guidelines for the design and development of AST training systems were presented in four categories: Voice Subsystems; Instructr Models; Simulation and Event Control; and Training System Executive. Computer speech recognition and generation were characterized as rapidly advancing technologies that are ready now for application in automated training systems. A human factors perspective was advanced by emphasizing the importance of the trainee in the design of complex automated training systems. Training effectiveness and user acceptance are objectivea to be sought through careful design of the Voice Subsystem and supporting models and subsystems described in the report. Both complex and simple applications of AST for training were addressed. The emphasis was on complex systems designed to reduce the need for instructors and other training support personnel. This reduction can be accomplished through speech interactive simulation and the automation of performance measurement, curriculum control, record keeping, and instructional presentation.
