Phoenix learned whistles, and Akeakamai learned sign language. Both dolphins understood the significance of the ordering of tasks in a sentence. A study conducted by Jason Bruck of the University of Chicago showed that bottlenose dolphins can remember whistles of other dolphins they had lived with after 20 years of separation. Each dolphin has ...

It translated seven vowel sounds spoken by humans to pure sine wave whistles from 7,000 Hz to 15,000 Hz. Thus the humans did not need to learn a whistled language, and the dolphins did not need to make human sounds. The equipment was analog, with filters which were able to distinguish vowel sounds and play the appropriate whistle frequencies.
