研究人员说声音是一个人未来性行为的预警信号。听到这个你是不是也吓了一跳呢?别不相信，这可是真的，他们认为声音低沉的男性更有可能对配偶不忠，而音调高的女性更有可能出轨。有了这个结论相信很多人看过以后都会去刻意的仔细听听对方的声音，然后判断一下是不是具有背叛的潜力呢?我想这只能是一种外在的表现吧，也并不是一个决定性因素，因此我们不能够完全的按照这个来定论一个人。

　　所以，为了保险起见，我们就找一个声音特难听的人来避免这种可能性。因为声音越有魅力的人——音调高的女性和音调低的男性——将来出轨的可能性越大。

　　Men with deep voices are more likely to cheat on their partners, women believe.

　　And men feel that if a woman has a high-pitched voice, she is more likely to be unfaithful.

　　The authors of the first study to examine the connection between voice pitch and fidelity say the findings show insights into how we pick our partners.

　　They say the voice could give a warning sign of future sexual behaviour.

　　The connection is down to hormones – the more testosterone a man has, the lower his voice, and the more oestrogen a woman has, the higher her voice is likely to be.

　　Researchers at Canada’s McMaster University asked people to listen to recorded clips of a male and female voice, which were electronically altered to become higher or lower pitched.

　　They were then asked to rate which one from each pair was more likely to cheat, reports the journal Evolutionary Psychology.

　　Lead author Jillian O’Connor said: ‘In terms of sexual strategy, we found that men and women will use voice pitch as a warning sign of future betrayal.

　　‘So the more attractive the voice – a higher pitch for women and lower pitch for men – the more likely the chances he or she will cheat.’
