概要
- 論文の詳細を見る
Chaos theory has recently given us a new insight into cardiology, otolaryngology, the nervous system, and psychiatry. Yeragani et al. found the phenomenon whereby chaos of heart rate time series diminished in patients with major depression. Drawing on recent developments in voice analyses, it is a well-known fact that the Japanese vowel / a / has chaotic characteristics of voice. We have empirically found that patients with depression have a specific vocal sound, that is, a low, discouraged, and sorrowful tone of voice. Furthermore, the screening tests for depression are self-reported and subjective, and depend on respondents' intention. To investigate the possibility of an objective depression scale, we investigated the relationship between depression and the chaos of vocal sounds.
