Imagine the sound of the largest toothed predator on Earth—a song echoing from the ocean’s depths. Unlike the melodic tunes of other whales, this sound resembles a digital data transfer. For centuries, sailors believed these eerie noises were the cries of lost souls at sea. It wasn’t until 1957 that scientists discovered these sounds were actually from whales, and by the 1970s, they realized these complex noises were a form of communication.
Researchers now think sperm whales might hold the key to breaking the barrier of inter-species communication. If any animal could possess a language similar to humans, sperm whales are strong contenders. Their brains are highly developed, and they lead rich social lives with complex communication systems. Their language might have evolved for reasons similar to ours, given their massive brains have existed for millions of years longer than ours.
Human fascination with speaking to animals is ancient, but now technology might make it possible. Advances in natural language processing, like ChatGPT, show what computers can achieve with human language. Scientists believe these techniques could be applied to understand sperm whale communication. Unlike simple songs, sperm whales and other animals might be conveying specific messages, possibly using a form of language.
Many animals have complex communication systems. For instance, prairie dogs have distinct alarm calls for different predators, and putty-nosed monkeys have specific calls for leopards. Bats use squeaks to convey information, and jumping spiders communicate through vibrations. While many species communicate, determining if they use language like humans is challenging.
Linguistics traditionally focused on human language, which has grammar, syntax, and the ability to convey information about different times. Whether other animals share these features remains unknown. Sperm whales, however, are promising candidates for testing non-human translation. They produce the loudest sounds of any creature, and their communication involves sequences of clicks called codas, which vary by region.
Since 2020, the Citation Translation Initiative has been studying sperm whales near Dominica. Scientists aim to collect data to help computers translate whale language. Machine translation has evolved, and recent advances allow for unsupervised translation, which could be applied to whale communication. By gathering extensive recordings, researchers hope to identify patterns in whale sounds.
Researchers study a 20 square kilometer area off Dominica, observing 50 to 400 whales depending on the season. Sperm whales vocalize almost constantly, with a significant portion of clicks used for communication. Autonomous devices record whale sounds from various angles, collecting massive amounts of bioacoustic data. This data is analyzed using machine learning to distinguish between echolocation and communication.
Despite progress, challenges remain. Variations in clicks could represent different meanings or simply pronunciation differences. Translating whale communication assumes they have a sense of self and emotions similar to humans. Even if translation proves difficult, recognizing patterns could reveal insights into whale lives and help in their conservation.
All ocean ecosystems face threats from climate change, affecting cetaceans significantly. Understanding whale communication could aid in addressing these challenges. Language has been a crucial tool for human innovation, and deciphering whale language might help us protect these magnificent creatures.
The origins of human language remain a mystery. Did it develop suddenly, or was it a gradual process of natural selection? This question is hotly debated in linguistics and archaeology.

This is the sound of the largest toothed predator on the planet—a song being broadcast from the deepest reaches of the sea. It resembles a digital data transfer more than a harmonious melody, unlike the sounds we hear from other whales. This sound has haunted sailors for centuries, who believed it to be the cries of drowned sailors calling out to them. Amazingly, it wasn’t until 1957 that scientists realized these sounds were actually coming from whales, and it wasn’t until the 1970s that they understood these undulating, clicking, bellowing noises were a form of communication.
Researchers now believe sperm whales could be our best chance at breaking a barrier we’ve never crossed, potentially holding the key to the first-ever case of inter-species communication. If you were to bet on one animal that might have something akin to human language, it would be the sperm whale. Over the years, scientists have learned that their brains are highly developed, and they have rich social and family lives, culture, and an intricate communication system. Their lives are similar to ours, and their language may have developed for similar reasons. They’ve had their massive brains for tens of millions of years longer than we have had ours, and with a vast repertoire of different sounds and intricate patterns, it seems sperm whale language could be as complex as our own.
Speaking with other animals has long been part of human imagination, folklore, and fantasy across many cultures. Now, for the first time, we have technology that might actually help us break the code. Recently, we’ve seen significant advancements in natural language processing, with models like ChatGPT providing a clear idea of what is possible when it comes to computers and human language. As technology has advanced dramatically over the last decade, scientists now think they can apply these techniques to inter-species communication, specifically with sperm whales.
Sperm whales and other species are not just singing to one another; they seem to be communicating specific messages, possibly even using language in a way we could understand. For thousands of years, humans have considered language to be a defining characteristic of our species, something that other animals couldn’t possibly approximate. However, with better technology, we’re starting to realize that many species have complex forms of communication.
For example, prairie dogs have distinctive alarm calls for different predators, and male and female putty-nosed monkeys produce their own alarm calls when leopards approach. Even bats use squeaks not just for echolocation but to convey information about themselves and others. Tiny jumping spiders communicate through vibrations. The animal kingdom is clearly full of species communicating, but recognizing whether they use language is much harder.
When linguistics developed as a field, it focused on analyzing the differences between human language and how it works. It seemed clear that nothing else on Earth communicated the way we do. Human language has grammar, syntax, and the ability to create new words to convey information about past, present, or future events. What we don’t know is if the same is true for any other animal.
Sperm whales seem to be the perfect candidates for testing our non-human translation abilities. They produce the loudest noises of any living creature, reaching up to 230 decibels. For reference, human eardrums rupture at sounds louder than 150 decibels. Sperm whale communities also use discrete sequences of clicks, called codas, which researchers believe are the basic communication units of their language. Codas differ between whales in different regions, and for the whales off the coast of Dominica, a typical coda has five clicks and lasts about four seconds.
Researchers have been studying a group of sperm whales around the Caribbean island of Dominica for over 15 years. The world’s largest interspecies communication effort, known as the Citation Translation Initiative, was launched in March 2020. Scientists will collect data from these whales to understand how computers might translate whale language.
Since 2014, machine translation has relied on an encoder-decoder deep learning model, which uses two separate neural networks. The encoder takes a sentence in one language and converts it into a sequence of numbers, while the decoder outputs a sentence in a different language. However, this system requires human supervision and known pairs of inputs and outputs.
In 2018, researchers discovered a method for completely unsupervised translation, allowing for the translation of languages without needing a Rosetta Stone. This development has scientists excited about applying it to sperm whales. They believe that if they can gather enough recordings, they might be able to identify patterns in whale communication.
To estimate how much data the SETI project might gather, scientists are studying a 20 square kilometer area off the coast of Dominica, where 50 to 400 whales are observed depending on the season. Sperm whales vocalize almost constantly, with about 25% of their clicks used for communication. A typical coda from these whales is about one click per second, which could yield hundreds of millions of clicks per year.
Researchers will use a variety of autonomous devices to continuously record the whales from different angles. Tethered buoy arrays will collect massive amounts of bioacoustic data, while recording devices attached to the whales will provide detailed recordings of their sounds and movements. Autonomous sound recording robots will also capture audio and video from multiple animals simultaneously.
The data collected will be analyzed using various machine learning tools to identify when a sperm whale is making a sound, whether it’s echolocation or communication. Researchers have already collected around 100,000 sperm whale codas and created an algorithm to analyze and categorize them accurately.
However, challenges remain. There are many variables in any given coda, making it difficult to determine what is meaningful. Variations in clicks may resemble differences in pronunciation or signify fundamental variations with different meanings. Additionally, translating whale communication assumes they have a sense of self and emotions similar to ours.
Even if researchers can collect all this information, translating the codas in a way that makes sense to us may be impossible. However, they hope to recognize patterns that could reveal more about the whales’ lives, families, and intentions. Understanding whales, whether successful or not, might also help us care for and protect them.
All ocean ecosystems are under threat from climate change, and cetaceans are among the most affected. The availability of food is changing, and human activity poses significant challenges to whale populations. Language has been a tool that allowed humans to innovate and solve problems, and understanding whale communication could help us address the challenges they face.
The origins of language in our species remain one of the greatest mysteries of modern science. Did language suddenly develop in humans, or did we earn our voices through a slow process of natural selection? This is a hotly debated topic in linguistics and archaeology.
