Research on links between peoples’ personality traits and their voices has primarily focused on other peoples’ personality judgments about a target person based on a target person’s vocal characteristics, particularly voice pitch. However, it remains unclear whether individual differences in voices are linked to actual individual differences in personality traits, and thus whether vocal characteristics are indeed valid cues to personality. Here, we investigate how the personality traits of the Five Factor Model of Personality, sociosexuality, and dominance are related to measured fundamental frequency (voice pitch) and formant frequencies (formant position). For this purpose, we conducted a secondary data analysis of a large sample (2,217 participants) from eleven different, independent datasets with a Bayesian approach. Results suggest substantial negative relationships between voice pitch and self-reported sociosexuality, dominance and extraversion in men and women. Thus, personality might at least partly be expressed in people’s voice pitch. Evidence for an association between formant frequencies and self-reported personality traits is not compelling but remains uncertain. We discuss potential underlying biological mechanisms of our effects and suggest a number of implications for future research.

人们的人格特质与声音之间的联系的研究主要集中在其他人根据目标人的声音特征（尤其是音调）对目标人的人格判断。但是，尚不清楚声音的个体差异是否与人格特征的实际个体差异相关联，因此，声音特征是否确实是对人格的有效暗示。在这里，我们研究人格，社会性别和主导地位的五因素模型的人格特征如何与测得的基本频率（语音音高）和共振峰频率（共振峰位置）相关。为此，我们使用贝叶斯方法对来自11个不同独立数据集的大量样本（2,217名参与者）进行了二次数据分析。结果表明，男女之间的语音音调和自我报告的社会性别，支配性和外向性之间存在显着的负相关关系。因此，人格至少可以部分地表达在人们的语调中。共振峰频率与自我报告的人格特质之间存在关联的证据并不令人信服，但仍不确定。我们讨论了影响我们潜在的潜在生物学机制，并提出了一些对未来研究的启示。
