A man's voice is an indicator of his body strength, according to a study.
研究表明，男人的声音是力量的体现。

The study, led by Aaron Sell at the University of California, found that women can accurately assess a man's body strength based on his voice alone, suggesting that the male voice may have evolved as an indicator of fighting ability.
加利福尼亚大学教授艾伦塞尔带领研究的实验表明，女性可以依据男性的声音精确判断其体力，研究人员故而推测：声音或许已经进化成为衡量男人战斗能力的标准。 

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.
研究人员记录了来自美国、阿根廷、玻利维亚和罗马尼亚的200名男性受试者不断重复各自方言，同时，研究人员还对他们进行了一系列体能测试。

After listening to the recordings, university female students could accurately predict the strength of the men, based on a seven-point scale. The voice analysis provided just as much information about a speaker's strength as photographs.
接下来，研究人员请女大学生只听录音，然后凭感觉给受试者的体力打分，满分为7分。结果发现，她们都能准确评估出受试者的体力，即她们感觉比较强壮(弱小)的男性，在照片上看来也比较强壮(弱小)。

What aspects of voice women link with strength remain unknown. The study was published in the journal Proceedings of the Royal Society.

是什么能让女性仅仅依据男性的声音就可判断出其体力仍然是个谜。该研究结果发表在英国《皇家学会生物学分会学报》上面。
