We’ve heard of the physical effects on our body when we are talking to someone we are attracted to, like pupils getting larger or butterflies in our stomach.
Apparently, if their feet are facing towards us, that’s a good sign. If their arms are folded, not so much. But you can also gauge the level of someone’s attraction by their voice.
Male and female pitch.
The biological gender differences in the human voice are very clear. Female voices have higher pitch and male voices have lower pitch.
These differences are thought to be because of evolutionary pressures such as mating choices. In the animal world, pitch is associated with larger animals that can cause a bigger threat.
So by lowering their pitch, males can show their physical dominance in front of their competitors and appear more sexually fit to females. As a result, women find men with lower-pitched voices more attractive. It’s the opposite for men, who are more attracted to women with higher-pitched voices, which is perceived as a marker for femininity.

Attractiveness in the voice is important for the impressions we give our potential partners. In research settings, this is studied by asking listeners to rate voices of people they have never seen as either attractive or unattractive.
