And we see this lower frequency formant here.

我们可以看到这个频峰。

And these aren't the only two formants your voice makes.

这并不是你声音发出唯一两个峰。

So longer frequencies can resonate and you get a lower second formant.

所以更长频率可以，你得到一个峰。

These amplified frequencies are called formants.

这些被放大频率被称为峰。

We can change which formants get amped up.

我们可以改变峰。

While women prefer low-pitched voices with a narrow formant spacing that suggest a larger body size.

而女性则更喜欢音调沉、间隔短男性声音因为它让人联想到高大威猛。

So only high frequencies can resonate here, and we get a high second formant.

所以只有高频才能在这里，我们得到一个高峰。

The electronics in the pedal are boosting certain frequencies, basically creating different combinations of formants that to our ear sound like vowels.

踏板上电子设备加强了某些频率，基本上创造了不同峰组合，在我们耳朵里听起来像元音。

If we work our way up from the bottom, labeling where we see peaks in the spectrum – what are called formants – we can see the two sounds have quite different arrangements.

如果我们从底部开始向上，标记我们在频谱中看到峰值位置——所谓峰——我们可以看到这两种声音有完全不同排列。
