听力原文： Voice One: A bottlenose dolphin named Maui plays a computer game, helping scientists create a unique language [that] they hope humans and dolphins will understand.
It's not based on human words, but on a specific dolphin sound. Guess which one. Not its bark, or its clicks, made famous by Flipper. Words in this new language are whistled.
Dolphins typically whistle to each other under water, through a special structure just beneath their blowhole. Researchers say their whistles have meaning. For example, each dolphin learns from its mom its own signature whistle. So in human terms when they greet each other, it's not just, "Hi" It's, "Hi, my name is ..."--in this case, Maui.
Ken Marten and his team at Earthtrust in Sea Life Park Research Lab in Hawaii want to better understand how dolphins communicate. So for the next ten years, they will literally whistle while they work, creating this special language.
Voice Two: The rest of my career is dedicated to talking to these guys, so I guess you could call me Doctor Dolittle now.
Voice One: After studying dolphin whistles, Marten invented distinct whistles for various objects with which dolphins are familiar.
Which sound can be thought as dolphin's words？

A. Its bark.
B. Its clicks.
C. Its whistle.
D. Its crying.
