In this paper, we propose a criterion for designing practical voice recognition systems. In order to find out the criterion, psychological experiments were performed. In the experiments, subjects judged their degree of satisfaction with experimental voice recognition systems by 7 point scaling (from-3 to +3). It was found that the psychological satisfaction rate for the total system and the recognition capability had a positive corelation with the recognition accuracy. Moreover, it was observed that the satisfaction rate for the recognition capability constantly exceeded that for the total system. It seemed that the satisfaction rate for the total system was formed basically on the recognition capability and it was debased by other factors of the system. From these results, we thought that there was a possibility that if the system's recognition accuracy can be anticipated, the designer can foresee the user's satisfaction rate for the system. This can be a criterion for the recognition accuracy. This criterion can lead to a systematic method to design voice recognition systems. Some results of experiments with 2 types of systems were also described from the view point of this criterion.
