Summary:
In this study, we focused on the fatigue of workers engaged in driving a car, collected fatigue measurement indexes before and after driving. We compared changes in the conventional physiological index with in the proposed speech indexes. As a result, it was found that there were significant differences in some of proposed indexes before and after driving. Furthermore, we examined whether the self-evaluation values of speech index, physiological index and fatigue can be estimated by multiple regression analysis. As a result, it was shown that the feeling of fatigue can be calculated using the fundamental frequency when saying "korehajikkendesu". In this study, a model for estimating the fundamental frequency and the feeling of fatigue of one type of word could only be created, but in the future, it is necessary to perform multiple regression analysis using speech indexes and physiological indexes.
