Abstract. The first goal of the present study was to explore how 21 voice measures related to self-reported personality and communication styles. The second goal was to test the assertion of Trait Activation Theory (TAT) that traits are activated in relevant situations and that verbal behavior is the result of an interplay between individual differences and situations. The voice of 138 participants was measured in the lab via steady voice and continuous speech tasks, whereas personality and communication styles were self-reported using the HEXACO and Communication Styles Inventory. To test TAT, four scenarios were developed to activate the communication styles of Informality and Expressiveness. It was hypothesized that the activated communication styles will interact with relevant situations and will be expressed through changes in voice (i.e., pitch variation). Regarding the first goal, an explorative approach revealed that voice characteristics are informative mainly for the personality traits of Openness to Experience, Emotionality, and Conscientiousness and the communication styles of Emotionality and Questioningness. Regarding the second goal, the interactions between situations and communication styles provided mixed support for TAT. Implications and limitations of the study are discussed.

你的声音透露了你什么？

摘要。本研究的第一个目标是探索 21 种语音测量如何与自我报告的个性和沟通方式相关。第二个目标是测试特质激活理论 (TAT) 的断言，即特质在相关情况下被激活，而言语行为是个体差异和情境相互作用的结果。138 名参与者的声音在实验室通过稳定的声音和连续的语音任务进行测量，而个性和沟通方式则使用 HEXACO 和沟通方式量表进行自我报告。为了测试 TAT，开发了四个场景来激活非正式性和表达性的沟通方式。假设激活的沟通方式将与相关情况相互作用，并通过声音的变化来表达（即，音高变化）。关于第一个目标，一种探索性的方法表明，语音特征主要针对经验开放性、情感性和责任心的人格特征以及情感性和提问性的沟通方式提供信息。关于第二个目标，情境和沟通方式之间的相互作用为 TAT 提供了混合支持。讨论了该研究的意义和局限性。
