A spectrogram is plotting that information over time.

频谱图随时间绘制该信息。

Yeah, it's called a spectrogram because it represents the entire spectrum of what we can hear.

是的，它被称为频谱图， 因为它代表了我们可以听到的整个频谱。

The spectrograms froze the nighttime bird calls in time.

乔布斯：频谱图及时冻结了夜间的鸟叫声。

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

乔布斯：基本上，本杰明所的频谱图是夜间航班呼叫音频的纹。

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

声谱图就像发出声音的声纹。

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

因此，您实际上可以在声音本身以及频谱图上进行工智能训练。

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

乔将他在频谱图上看到的呼叫比作乐谱上的音符。

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

因此，他转向专门的计算机软件，将他听到的声音转换为称为频谱图的图像。

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

要想真正做到这一点，我们需要以一种完全不同的方式查看数据：频谱图。

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

他认出了他在频谱图中一遍又一遍看到的形状，但他无法理解它们。

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，查看频谱图并能够放大真正短的频谱图，对于识别能力会产生巨大的影响。

Once a database of dolphin sounds was created, the program identified subsequent dolphins by their sounds nearly as well as humans who eyeballed the whistles' spectrograms.

一旦一个海豚音的数据库产生了，接下来这个程序就可以通过声音来识别海豚了，类也可以用眼睛看到声音的声谱图。

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.

在分析了鸟儿歌声的频谱图后，该应用程序会给出对在您面前唱歌的鸟种的最佳猜测。

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，计算机学会了区分一个物种和另一个物种的能力。

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：他学会了识别他在任何特定夜晚都会听到的大多数叫声。
