Researchers from China's Southwest University recorded the voices of 88 men and 128 women, then had them fill out a form to assess their attitudes towards infidelity. Men with deep voices are more likely to attract a partner, but are also more likely to cheat on their partner - due to high levels of testosterone, according to a 2020 study. Researchers say it has so far been unclear as to whether vocal characteristics reveal aspects of our personality. Researchers admit that they gathered information about speaker’s personality via self-report questionnaires only – which may not align with their true character.įuture studies should therefore investigate the associations between voice pitch and personality traits when gathering reports from friends or family members, for example. The team found 'no compelling evidence' for a substantial link between voice pitch and the other big five traits – neuroticism, openness and conscientiousness.Īs such, the findings suggest that personality might at least partly be expressed in people's voice pitch, according to the team. The other hypothesis – that participants with lower voice pitch would self-report as lower on agreeableness (one of the big five) – was not supported. This supported three of the researchers' four hypothesis before the study. The results indicated that participants with lower voice pitch were more dominant, extroverted and 'unrestricted' when it came to their on sociosexual behaviour – including orientation, attitudes and desires. Stern and colleagues point to a 2020 study that found lower voice pitch in men is linked to higher levels of testosterone – however, the link for women 'seems to be less clear', the team admit. 'One possible explanation for our findings is that higher levels of testosterone are linked to lower voices and more unrestricted sociosexual orientation in both women and men,' said the study's lead author, Julia Stern at the University of Goettingen.

'We provide the first evidence that voice pitch might be a valid cue to at least some self-reported personality traits in men and women, including extraversion, dominance sociosexual orientation.'Ī potential biological mechanism influencing the relationship between voice pitch and the personality traits might be testosterone. 'Personality might at least partly be expressed in voice pitch in men and women,' the team say in their research paper, published in Journal of Research in Personality. The study was authored by experts at the University of Glasgow and the University of Strathclyde, as well as other institutions in Germany, Denmark, Canada and the US.
