This summer in the Bahamas, researchers will test new technology that helps humans get one step closer to communicating with dolphins using a series of whistles that dolphins can easily reproduce.
An underwater computer called the CHAT interface will broadcast artificial whistles through speakers, and then, if the dolphins start copying the whistles, will “translate” the sounds back into English. The test is starting small, using whistles for a few toys that dolphins like to play with–seaweed, ropes, and scarves. Since dolphins also use whistles to call each other by name, the machine will also create whistle names for each of the researchers.
