So you can actually have an artificial intelligence, it's a kind of training done on the sound itself but also on the spectrogram.

所以你可以使用人，这是一种对声音身和声谱图的训。

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，人类也可以用眼睛看到声音的声谱图。
