Or this.

And then, Wiki's trainers asked her to imitate them, speaking English.

Here's how she did.

Amy!

Hello!

Pretty impressive, especially because she's using her nasal passages to imitate sounds we make with our vocal cords.

And a technical acoustic analysis of the original and imitated sounds showed that Wiki was doing a reliable job of mimicry,

suggesting Orcas do indeed possess the ability of vocal imitation.

The study is in the proceedings of the Royal Society

B. So how long before Wiki's speaking fluent English? Well, this is not our goal. Study author
