The human voice conveys plenty of information about the speaker. A prevalent assumption is that stress-related changes in the human body affect speech production, thus affecting voice features. This suggests that voice data may be an easy-to-capture measure of everyday stress levels and can thus serve as a warning signal of stress-related health consequences. However, previous research is limited (i.e., has induced stress only through artificial tasks or has investigated only short-term or extreme stressors), leaving it open whether everyday work stressors are associated with voice features. Thus, our participants (111 adult working individuals) took part in a 1-week diary study (Sunday until Sunday), in which they provided voice messages and self-report data on daily work stressors. Results showed that work stressors were associated with voice features such as increased speech rate and voice intensity. We discuss theoretical, practical, and ethical implications regarding the voice as an indicator of psychological states.
人类的声音传达了大量关于说话者的信息。一个普遍的假设是，人体与压力相关的变化会影响言语产生，从而影响声音特征。这表明，声音数据可能是一种易于捕捉的日常压力水平的衡量指标，因此可以作为与压力相关的健康后果的预警信号。然而，之前的研究受到限制（即，仅通过人工任务引起压力，或仅研究短期或极端压力源），因此尚不清楚日常工作压力源是否与声音特征相关。因此，我们的参与者（111 名成年工作者）参加了为期一周的日记研究（周日至周日），在此期间，他们提供了语音信息和每日工作压力源的自我报告数据。结果表明，工作压力源与声音特征（如语速加快和声音强度增加）相关。我们讨论了将声音作为心理状态指标的理论、实践和伦理意义。
