Scientists Caught Whales Talking Like Humans Underwater
According to research published in Proceedings of the Royal Society B , sperm whales may be speaking to each other through a series of clicks that, while still seemingly alien to us on the surface, is a lot more like human speech than scientists expected once they dug into it. The work comes from Project CETI, a group trying to decode whale communication using machine learning and large audio datasets. According to the team’s latest analysis, the clicks sperm whales make as they communicate with one another, known as codas, aren’t just random noise. They follow structured, rule-based patterns that resemble the very same ones we use to talk to one another. After analyzing thousands of whale codas, the team thinks they behave much like vowels in human speech. There are distinct types of codas that are differentiated by a variety of variables like length, tone, and internal structure, which the scientists have labeled like human vowels – “a-codas” and “i-codas” and so on.
