| Siri's gentle voice in the new iPhone 4S has initiated fuss over the voice's sex and a larger question: why are so many computerized voices female? |
新型iPhone 4S手机里丝莉（Siri）温柔的嗓音引发了对该声音性别的猜测。与此同时，一个更大的问题摆在我们面前：为什么电脑发声都为女性的嗓音？ |
| According to a CNN report, one answer may lie in biology. Scientific studies have shown that people generally find women's voices more pleasing than men's. |
据美国有线电视新闻网报道，一种解答可能与生物学有关。科学研究表明人们普遍认为女性的声音比男性更为温柔。 |
| Research suggests this preference starts as early as the womb in which fetuses were found to react to the sound of their mother's voice but not to other female voices. |
研究发现胚胎会对母亲的嗓音做出反应，但对其他女性的嗓音却不会，暗示这种偏好也许在母体的子宫内部就已经形成。 |
| The fetuses showed no distinct reaction, however, to their father's voice. |
此外胚胎对父亲的声音也没有反应。 |
|
Another answer lies in history. According to some sources, the use of female voices in navigation devices dates back to World War II, when women's voices were employed in airplane cockpits because they stood out among the male pilots.

另一种解答与历史相关。据称，使用女性嗓音进行导航可以追溯至二战，驾驶舱内传出女性的声音能和其他男性飞行员的声音构成鲜明对比。 |
