Does emotion recognition by natural speaking voice detect emotion changes in military personnel exposed to mental stress?
Emotion recognition by natural speaking voice may be useful for screening mental status in military personnel exposed to stress.
Post Traumatic Stress Disorder (PTSD), depression and suicide are major psychiatric problem in both military and civilian situation. These mental diseases combine with emotion change. Recently, the technology of emotion recognition has been developed rapidly and highly. Therefore, we investigate if the emotion recognition by natural speaking voice could detect the emotion change which would occur when exposing mental stress. We used "Sensibility technology ST Emotion" (AGI Japan Inc.) for emotion voice analysis system. This system determines emotional elements as including anger, joy, sorrow, and calmness. It also measures feeling of excitement. Voice data were collected from the personnel of military medical corps participating in a special stressful mission. The voice data were divided into two groups depending on participating period. Some subject's feelings during experimental period were changed. There is a tendency that "joy" of long stay group (Group L) is lower than short stay group (Group S) and "sorrow" of Group L is higher than Group S. The result suggested that the techniques of emotion recognition may be used for screening of mental status in military situation. However, further development is necessary for practical use.
Tokuno et al. (Mon,) conducted a observational in Mental stress. Long stay in stressful mission (Group L) vs. Short stay in stressful mission (Group S) was evaluated on Emotion change (anger, joy, sorrow, calmness, and excitement) detected by voice analysis. Emotion voice analysis detected a tendency for lower joy and higher sorrow in military personnel with a long stay in a stressful mission compared to those with a short stay.
