DI@L-log is an automated medical spoken dialogue system designed to enable patients to regularly communicate health data to the point-of-care over the telephone. In order to investigate the performance of the system, a preliminary evaluation was conducted using 5 novice hypertensive diabetic patients from the Ulster Hospital in Northern Ireland. The purpose of the study was to assess several factors which need to be addressed when designing spoken dialogue systems for elderly, disabled users. We examined the performance of the system, the interaction preferences of the user and their usage patterns, the level of user satisfaction, and the impact of the system on the patient’s health over time. A revised version of the system, modified to take account of findings from this study, is currently undergoing testing with a larger group of subjects.
