ScienceDaily (Oct. 29, 2008) — A new UCLA study adds to mounting evidence that human ovulation — a state once thought to be undetectable without medical equipment — actually prompts a range of subtle but observable behaviors aimed at attracting the best possible mate.
The authors show for the first time that women unconsciously change their voices with the approach of ovulation, using a higher, more feminine pitch in social communication.
Operating on the assumption that higher pitch is generally perceived as more attractive and more feminine, researchers recorded the voices of 69 women during two phases of their ovulatory cycle: once when fertility was low and once near ovulation (confirmed using hormone tests). The closer women were to ovulation, the more they raised their pitch. This difference was found only when women spoke a simple introductory sentence — "Hi, I'm student at UCLA" — and not for simple vowel sounds.
The study shows that women unconsciously change their voice in relation to fertility, and possibly only in social communication contexts. This change is part of a suite of behaviors women engage in during high fertility, research is now finding. Other changes have been detected in how they dress, how they walk and the mates they prefer. Higher voice pitch in women indicates the presence of feminizing hormones, and it also correlates with being younger. Both qualities tend to correlate with high fertility, so men have evolved to be attracted to these cues.
Authors of the study include Gregory A. Bryant, a UCLA assistant professor of communication studies, and Martie G. Haselton, a UCLA associate professor of communication studies and psychology.

[post]Women's Voices Become More High-pitched During Ovulation
女性的声音在排卵期会变得更高调
Science Daily (Oct. 29, 2008) — A new UCLA study adds to mounting evidence that human ovulation — a state once thought to be undetectable without medical equipment — actually prompts a range of subtle but observable behaviors aimed at attracting the best possible mate.
科学日报（2008年10月29日）——一项UCLA的研究表明人类的排卵期——一种曾经被认为是无法用医学仪器发现的状态——实际上表现在一系列可察觉的行为上，而这些行为是为了吸引异性的。
The authors show for the first time that women unconsciously change their voices with the approach of ovulation, using a higher, more feminine pitch in social communication.
作者第一次阐述说，女性在近排卵期时，会在社会交际中不自觉地改变她们的声音，使其变得更高，更阴柔。
Operating on the assumption that higher pitch is generally perceived as more attractive and more feminine, researchers recorded the voices of 69 women during two phases of their ovulatory cycle: once when fertility was low and once near ovulation (confirmed using hormone tests). The closer women were to ovulation, the more they raised their pitch. This difference was found only when women spoke a simple introductory sentence — "Hi, I'm student at UCLA" — and not for simple vowel sounds.
更高的音调被普遍认为是更具有吸引力和更女性化，为研究这一点，研究者选择了69个女性研究对象，在她们排卵周期的两个阶段，记录她们的声音:一次是她们繁殖力较低时，一次是她们接近排卵时(用激素的水平测试)。越是接近排卵，她们音调抬得更高。这种差别只有在她们作简短的自我介绍的时候才容易被发现——“大家好，我是UCLA的一位学生”——并且不是简单的元音发音是这样。
The study shows that women unconsciously change their voice in relation to fertility, and possibly only in social communication contexts. This change is part of a suite of behaviors women engage in during high fertility, research is now finding. Other changes have been detected in how they dress, how they walk and the mates they prefer. Higher voice pitch in women indicates the presence of feminizing hormones, and it also correlates with being younger. Both qualities tend to correlate with high fertility, so men have evolved to be attracted to these cues.
研究显示，女性在繁殖期会不自觉地改变她们的声音，这种改变可能只在社会场合中。研究现在发现这种变化只是她们在繁殖期中的一系列行为改变之一。其它改变就比如她们怎么穿着，怎么走路和更喜欢什么样的异性。高音调的声音显示女性激素的作用，并且这和她们较年轻也有关联。这两个因素与繁殖力高有关，所以男性对于这些人来说是容易被吸引的。
