Assessment of the VoiceMap spoken language system

As spoken language systems expand to new tasks, there will be a need for empirical research on how to optimize the usability of human-computer spoken natural language dialogues, including research on methods for chunking information. For allowing users to control provision of that information, and for providing feedback on the system's processing and current context. The paper describes the results of usability study performed to evaluate the performance and usability as well as acceptability of a system that provides street map directions. >
