Outline of Final Research Achievements

We propose a method that uses speech analysis to measure speaker fatigue to develop a fatigue measurement system. Our proposed method uses the following three measurement indexes: fundamental frequency, average speech power, and speech period. We performed four experiments in which subjects conducted Advanced Trail Making Test, rode on a bicycle simulator, a driving-simulator, and a bicycle ergometer. Our bicycle-simulator experiment and driving-simulator experiment results suggest that our method might be an effective fatigue measurement index for acute fatigue.
