Previous studies have shown that human voice has an important role in communicating different traits, by implying speaker's sex, age, physical height, etc. Studies have also found correlations between various vocal characteristics and perceived personality traits. For example, there is evidence that higher pitch is positively related to perceived femininity, while lower pitch is related to perceived dominance. The aim of the present study was to investigate those relationships between voice and personality, by focusing on women's self- -reports of masculinity, femininity, dominance and affiliation. 48 women were recorded three times during vowel /a/ production. After acoustic analysis, it was found that voice pitch was not related to personality traits. On the contrary, pitch variability was negatively related to masculinity, and positively to femininity. Furthermore, shimmer was positively, and harmonics to noise ratio negatively related to self- -reported masculinity. Further regression analyses confirmed contribution of pitch variability and shimmer in explaining individual differences in masculinity. Besides the interpretation of the results in the context of previous findings, we discuss possible directions for future research in order to improve research methodology.

女性声音的声学特性与自我报告的人格特征之间的关系

先前的研究表明，人的声音通过暗示说话者的性别，年龄，身高等，在传达不同的特征方面具有重要作用。研究还发现，各种声音特征与感知的人格特征之间存在相关性。例如，有证据表明，较高的音调与感知的女性气质正相关，而较低的音调与感知的女性气质正相关。本研究的目的是通过关注女性对男性气质，女性气质，主导地位和隶属关系的自我报告，来研究声音与人格之间的关系。在元音/ a /制作过程中，有48位妇女被记录了3次。经过声学分析，发现音高与人格特质无关。相反，音高变化与男性气质负相关，并积极提升女性气质。此外，微光是正向的，谐波噪声比与自我报告的男性气质负相关。进一步的回归分析证实了音高变化和微光有助于解释男性气概的个体差异。除了在先前发现的背景下解释结果之外，我们还讨论了未来研究的可能方向，以改进研究方法。
