Previous experiments have shown that voice pitch (the perception of fundamental frequency and/or corresponding harmonics) is positively associated with women’s voice attractiveness, however all of this research is on women’s speaking voices. Singing is important for the mating success of non-human animals, is cross-culturally universal in humans, and is highly sexualized in many cultures. Thus, singing could contribute to mating success and attraction in humans. First, we investigated whether previous findings, that high voice pitch when speaking predicts women’s voice attractiveness, extend to when women sing. We also examined whether pitch- and rhythm accuracy contribute to women’s singing voice attractiveness. Voice pitch was positively related to women’s singing voice attractiveness as judged by men more than when judged by women, and speaking voice attractiveness was positively related to singing voice attractiveness. Thus, men and women may be reacting to the same indicator of women’s underlying quality (i.e. voice pitch) in both women’s speaking and singing voices, differently. Men may be attracted to high pitch, whereas women may show a weaker relationship, as they tend to be more romantically jealous of women with high pitched voices. Pitch- and rhythm accuracy did not predict women’s singing voice attractiveness. This result can be interpreted in different ways. It could mean that women’s voice pitch may be more important in determining men’s perceptions of their singing voice attractiveness than is their singing ability, or our measures were ill suited to the task. Collectively, these results are the first to show that singing voices are more attractive than speaking voices, people with attractive speaking voices tend to have attractive singing voices, and that singing and speaking voices relate to the same underlying qualities. Thus, singing may be an indicator of mate value and could have played a role in the evolution of sex differences in the voice if our ancestors had similar preferences. / Thesis / Master of Science (MSc)
