Israeli And US Scientists Aim To Talk To Whales — What Will They Say?

In an ambitious and unprecedented five-year study, top research institutes plan to learn how to communicate with sperm whales. 

It’s well known that whales communicate with one another, but what if humans could understand what they say, and communicate their own thoughts back to them?

That’s what marine scientists from the University of Haifa in Israel and top universities across the world hope to do with a new five-year research study to decipher how sperm whales communicate and whether their speech patterns can be replicated so that humans can communicate with them.

The new interdisciplinary Cetacean Translation Initiative (CETI) kicks off this week at a press conference in Dominica in the Caribbean, where the project will take place.

University of Haifa scientists will be joined by colleagues in marine biology, marine acoustics, artificial intelligence, and linguistics from Harvard University, City University of New York, Massachusetts Institute of Technology, Imperial College London, University of California-Berkeley and others.

Researchers will use state-of-the-art machine learning and noninvasive robotics to listen and translate the sperm whales’ language and even attempt to talk back to these beautiful and increasingly rare creatures.

Complex conversation and tightly knit family

The sperm whale, which is considered a vulnerable species, has the largest brain on Earth, more than five times heavier than a human’s. Like humans, it also has a complex communication system and lives in tightly knit family groups.

These whales can grow up to 20.7 meters (68 feet) and live for 70 years or more. They are vital to our environment because they keep carbon out of the atmosphere, support our oxygen supply and increase marine life.

“These primates make a clicking sound at varying frequencies when they are in the company of other whales. The question is, is this just a simple code or a true language?” said professor Dan Tchernov of University of Haifa’s Leon H. Charney School of Marine Sciences, one of the project leaders.

“Right now, our database is not comprehensive enough to know the answer to this question. However, with the advancement of machine learning, and advanced linguistics, we realized that if we gathered enough data about their voices, the context in which these sounds are employed and understood and their behavior and motivation behind these sounds, we can then develop an algorithm which will determine whether they have an authentic language.

“Of course, the dream would be if we are able to communicate with them, on their terms,” said Tchernov, who is also scientific director of the Morris Kahn Marine Research Station.

Dwindling biodiversity

The potential implications of the project are numerous since the biodiversity of the planet is dwindling fast, and humanity must find a way to coexist with the creatures that remain on earth.

Leading the project is professor David Gruber, Presidential Professor of Biology and Environmental Science at City University of New York, along with Shane Gero, a National Geographic explorer and an expert in whale biology who has investigated Dominica sperm whales for over a decade.

They will work with Tchernov, who is serving as the project’s operational director. Other researchers include University of California-Berkeley and MIT professor Shafi Goldwasser, and Harvard University’s robotic program director, professor Rob Wood.

Also part of the University of Haifa team are Roee Diamant of the Marine Sciences Department, who will be the project’s lead acoustic adviser and in change of placing the world’s most advanced marine mammal listening and localization array, and Bracha Nir, head of the university’s Department of Communication Disorders, who will investigate mother and calf communication themes.

“We now have the tools to identify and translate the deep structure of [the whales] communicative patterns and to kick-start the path towards meaningful dialogue with another species. By illustrating their incredible intelligence and advocating for legislation, we can accelerate conservation efforts,” states Project CETI’s official website, called appropriately enough, The Audacious Project.
