Women sometimes modify their voices to sound most attractive during the most fertile part of their menstrual cycle. We actually have the ability to change the attractiveness of our voice depending on our interlocutor, and we do this without knowing. There are many unconscious things we do when we’re flirting with someone. That is, the specific qualities that the raters were perceiving in the voices were indicative of these people’s mating behaviours and sexual desirability. Using this method, one study showed that people who reported being more sexually experienced and sexually active were rated to have more attractive voices by strangers. In research settings, this is studied by asking listeners to rate voices of people they have never seen as either attractive or unattractive. It’s the opposite for men, who are more attracted to women with higher-pitched voices, which is perceived as a marker for femininity.Īttractiveness in the voice is important for the impressions we give our potential partners. As a result, women find men with lower-pitched voices more attractive. So by lowering their pitch, males can show their physical dominance in front of their competitors and appear more sexually fit to females. In the animal world, pitch is associated with larger animals that can cause a bigger threat. These differences are thought to be because of evolutionary pressures such as mating choices.
