Abstract: A subject experiment was conducted with the aim of developing a method for measuring stress using speech as non-contact information among human physiological responses. Compared to contact-type physiological reaction measurement methods such as salivary amylase activity, non-contact-type stress measurement methods can measure stress state in a short time without interfering with work because the measurement stress on the subject is small. Since the pitch and level of speech may be different between normal and stressed states depending on the behavior of the vocal cords, this study aims to develop a non-contact stress measurement method using speech. As a result of the subject experiment, regular changes were confirmed between the salivary amylase activity value, which is the contact physiological index of the subject before and after the task, and the formant value, F2-F1, which is the voice index and is the non-contact physiological index, with the exception of a few subjects.
