| Outline of Final Research Achievements |
Mass screening methods for estimating mental health status require accuracy and cost-effectiveness to be performed. Traditionally, self-administered questionnaire has been widely conducted for this purpose. However, it has some limitation: we cannot avoid underestimation by factitious responses. We herein, invented software to evaluate stress using novel speech emotion recognition technology available to screening for mental disorders. This system is based on principle that vocal code receives parasympathetic innervation which is susceptible to various stressors. A result shows the sensitivity and specificity of stress evaluation by voices are almost equivalent to those by the GHQ-30, and we are able to eliminate the reporting bias to pick up depression cases. There is still a room for this system for improvement to pursuit more accuracy.
