Scientists are making strides in decoding animal communication, and artificial intelligence (AI) is at the heart of it. And this success may raise the possibility that humans may one day hold a conversation with another species. According to a report by CNN, researchers using advanced recording equipment and machine learning have begun cracking the vocal codes of animals ranging from mice to chimpanzees to birds, revealing communication systems far more complex than previously imagined.
In South Africa's Karoo desert, a team led by Professor Nicolas Mathevon of the University of Saint-Etienne recorded over 122,000 squeaks from African striped mice across just 12 days. When Mathevon fed the data into an artificial neural network, which is the same technology that powers AI chatbots like ChatGPT, the team discovered that each nest of mice carries a unique vocal signature, and that individual mice can be identified by their calls alone.
“Not so long ago, people thought that animals were not communicating at all, or very simple things. Machine learning is absolutely essential - you have too many vocalisations, you cannot handle them manually,” said Mathevon.
Researchers also study apes, chimpanzees
Meanwhile, a separate group of researchers studying chimpanzees in Ivory Coast has found that the apes combine basic calls in pairs to create entirely new meanings that resembles the building blocks of human grammar. One combination translates roughly to “Let's build a nest.”
A separate study on bonobos in the Democratic Republic of Congo found similar patterns, with one paired call believed to mean something like “Let's make peace.”
Zebra finches also yielded surprises for researchers with one of them, Julie Elie at UC Berkeley, has shown that the birds not only recognise distinct calls but have a mental representation of what those calls mean. She describes this breakthrough as “starting to break the wall between our species and the rest of the animal kingdom.”
Scientists urge caution
Some scientists fear that the ability to communicate with animals could lead to exploitation, such as wildlife tourism that disrupts natural behaviours. Others warn that domesticated animals might finally get to voice their discomfort and humans may not like what they hear.
“I would love to speak to my cat. Unfortunately, it might be a limited conversation,” said Professor Yossi Yovel of Tel Aviv University. Still, even partial communication could have real-world benefits like improving farm animal welfare to preventing train collisions with deer using deer-alert sounds.
