1. The voice of love
There’s a subtle change in people’s voices when they speak to someone they love.
Despite the subtlety of these shifts in the voice, people can detect the changes by listening for just 2 seconds (Farley et al., 2013).
One of the study’s authors, Susan Hughes, explained that the voices of new lovers had a special tone:
“There was vulnerability associated with the voices of those newly in love. Perhaps people don’t want to be rejected.”
2. Women attracted to deeper voices
It’s hardly a revelation that women prefer men with deeper voices (Collins, 2000), although it does contain a mystery.
The mystery is: why? You might, quite sensibly, guess that it signals a taller man, more muscles, a hairy chest and so on.
But actually when women are tested, a deeper voice only tells a woman that a man probably weighs more. In other words, men with deeper voices can just as easily be short, fat and totally lacking in muscles or a hairy chest.
