London, June 16 (ANI): A man's voice is an indicator of his upper body strength, according to a study.he study, led by Aaron Sell at the University of California, Santa Barbara, found that both men and women can accurately assess a man's upper body strength based on his voice alone, suggesting that the male voice may have evolved as an indicator of fighting ability.
The researchers recorded the voices of more than 200 men from the US, Argentina, Bolivia and Romania, who all repeated a short phrase in their native tongue.
Sell's team also put the men through a battery of tests of upper body strength, reports New Scientist.
After listening to the recordings, university students could accurately predict the strength of the men, based on a seven-point scale from "weak" to "strong" - regardless of the language used.
The voice analysis provided just as much information about a speaker's strength as photographs.
What aspects of voice we link with strength remain unknown, since there was no correlation between a man's strength and the pitch or timbre of his voice.
That's surprising, said David Puts at Pennsylvania State University in University Park,since previous research showed deeper voices were rated as coming from stronger men.
The study was published in the journal Proceedings of the Royal Society. (ANI)
