Joe likens the calls he saw on the spectrograms to notes on sheet music.

乔把他在频谱图上看到的鸟叫声比作乐谱上的音符。

We feed the computer these spectrograms that we've classified as one species or another, and then, as we repeat that thousands and thousands of times, the computer learns to be able to distinguish one species from another.

我们把被归为各个物种的声谱图输入计算机，然后，随着我们成千上万次的重复，计算机就会了如何区分一个物种和另一个物种。

So looking at the spectrogram and being able to zoom in close on the really short ones makes a huge difference for the ability to identify.

因此，查看频谱图并能近距离放大非常短的声线，对识别能力的提高大有裨益。

So I learned how to upload little bits of sound, a little bit of spectrogram, onto Facebook posts.

所以我会了如何把声音的一小段一小段频谱图 上传到“脸书”的帖子里。

After analyzing the spectrogram of the bird's song, the app spits out its best guess as to what species of bird is singing in front of you.

在对鸟鸣的声谱图进行分析后，该应用程序就会给出最佳猜测，告诉你在你面前唱歌的是什么鸟。

So he turned to specialized computer software to transform the sounds he was hearing into images called spectrograms.

于是，他求助于专门的计算机软件，将他听到的声音转换成被称为“频谱图”的图像。

He recognized shapes he was seeing over and over in the spectrograms, but he couldn't make sense of them.

他认出了自己在频谱图上反复看到的形状，但他无法理解这些形状。

A spectrogram is plotting that information over time.

声谱图是随着时间绘制这些信息。

A spectrogram is a way to represent sound on a graph.

频谱图是一种在图表上表示声音的方法。

But they have since proven that basically using spectrogram analysis.

但他们后来通过频谱图分析证明了这一点。

One is a folder containing photographs and audio spectrograms.

一个是包含照片和音频频谱图的文件夹。

During the autumn and winter of 1912, he obtained a series of spectrograms from the largest of the spiral nebulae, which was located in the constellation of Andromeda and known at the time as the Andromeda Nebula.

1912年秋冬季， 斯莱弗从最大的旋涡星云中获得了一系列光谱图，该星云位于仙女座， 当时被称为仙女座星云。

A spectrogram is like a visual voiceprint of whatever made the sound.

频谱图就像是发声者的视觉声纹。

So you can actually have an artificial intelligence training done on the sound itself but also on the spectrogram.

所以你可以实际利用声音本身以及频谱图来训练工智能。

Van Doren: We feed the computer these spectrograms that we've classified as one species or another, and then, as we repeat that thousands and thousands of times, the computer learns to be able to distinguish one species from another.

范多伦：我们将这些被我们分类为一个物种或另一个物种的光谱图输入计算机，然后，当我们重复数千次时，计算机会了区分一个物种和另一个物种的能力。

It's tough without bird ears, because we're really only talking about like a few hundred hertz, which is why the scientists use these things called spectrograms.

没有鸟儿的耳朵， 事情就变得棘手了， 因为我们讨论的仅仅是几百赫兹的范围，这就是为什么家们使用一种叫做频谱图的工具。

The spectrograms froze the nighttime bird calls in time.

频谱图将夜晚某一段的鸟叫声定格。

To really make this pop out, we need to view the data in a totally different way: a spectrogram.

要让这个效果突出，我们需要以完全不同的方式来看待数据：频谱图。

Along the way, I went from not knowing what Chipping Sparrow and Swainson's Thrush calls looked like on the spectrogram until ... Job: He learned to identify most of the calls he would hear on any given night.

Gyekis：一路走来，我从不知道碎麻雀和斯温森画眉鸟的叫声在频谱图上是什么样子，直到...... 乔布斯：他会了识别他在任何特定夜晚都会听到的大多数叫声。

Basically the spectrograms Benjamin is referring to are visual fingerprints of nocturnal flight call audio.

乔布斯：基本上，本杰明所指的频谱图是夜间航班呼叫音频的视觉指纹。
