System Design for Speech Recognition and Generation

This article reviews human factors research on the design of systems that use speech recognition for human control of the system or that use speech generation for the display of information. Speech technology terms are defined and the current status of the field is reviewed. Included are the performance of current speech recognition and generation algorithms, descriptions of several applications of the technology to particular tasks, and a discussion of research on design principles for speech interfaces. Finally, directions for further research are suggested. The need for better simulation techniques and performance measures is stressed, as is the importance of considering the entire system in which speech technology will function.
