With clicks and whistles, these three dolphins are obviously communicating something,
三只海豚发出咔哒声和口哨声，很明显它们在进行交流，
as they wait for the fish thrown by their trainers in Sweden's Kolmarden Wildlife Park.
这是在瑞典的科尔莫登野生动物园里，三只海豚等待驯兽师扔鱼的时候发生的一幕。
Dolphins do not have vocal cords, so the sounds are coming from their blowholes.
海豚没有声带，所以声音来自它们的气孔。
And we can hear only a part of their tonal range, says senior zoological adviser Mats Almundin.
资深动物学顾问马茨·阿尔芒丁说，我们能听到的只是它们音频频段的一部分。
They use frequencies that we can't hear, they can, they use frequencies up to 150 kilohertz.
它们使用的频率我们听不到，它们使用的频率高达150千赫兹。
So, we have to have devices that brings that down to something that we can even detect.
所以我们必须使用设备，把频率降到我们能够测到的水平。
While using an underwater microphone to record dolphins' sounds, Almundin observes a certain pattern.
当使用水下麦克风记录海豚的声音时，阿尔芒丁观察到一种特定的模式。
We have found a combination of a whistle and a burst pulse sound that we believe is a giggle, you know.
我们发现一种哨音和一阵脉冲声音的组合，我们觉得那是一阵咯咯笑，你知道的。
So, yeah, we know a little but not so much.
所以，是的，我们略知一二，但不是那么多。
In order to learn more, scientists from Sweden's Royal Institute of Technology teamed up with language analysis company, Gavagai AB.
为了了解更多信息，瑞典皇家理工学院的科学家与语言分析公司Gavagai AB合作。
Digitized dolphin sounds are fed into a powerful software
将海豚声音数字化，并将其输入到一个强大的软件分析中，
analyzing how often a certain sound occurs in which situation, trying to find more patterns and meaning.
分析在某种情况下发生某种声音的频率，试图找到更多的模式和含义。
But understanding dolphins may require developing a whole different concept of language,
但理解海豚可能需要发展一种完全不同的语言概念，
says associate professor of phonetics at Linkoping University, Robert Eklund.
林雪平大学的语音学副教授罗伯特·埃克隆德说。
We has a smart animal here. We have a pretty smart animal here and we have our communicative systems.
海豚是非常聪明的动物，人类也是非常聪明的动物，而且拥有自己的交流系统。
They have theirs. We have ours and can we actually cross the divide here and talk to each other?
它们也有自己的沟通方式，我们有我们的，我们能不能跨越鸿沟实现真正的沟通呢？
To some extent yes, we can. We would know that but to what extent can we expand on that?
在某些方面是的我们可以，我们已经知道了，但我们又能在多大程度上扩大这一点呢？
Gavagai AB CEO Lars Hamberg says breaking the language barrier between humans and animals may have important outcomes.
Gavagai AB的首席执行官拉斯·汉伯格说，打破人类和动物之间的语言障碍可能有重要的结果。
Just being able to communicate at some level with the animals may give us a different perspective, not only on the animals but also on ourselves.
只要能够与动物进行某种程度的交流，就可以给我们一个不同的视角，不仅对动物而且对我们自己。
Hamberg says understanding dolphins language may also help computer scientists develop better pattern recognition technology.
汉伯格说了解海豚语言也可以帮助计算机科学家开发更好的模式识别技术。
