C1 Business English · AI and Innovation
Scientists are using AI to decode the language of sperm whales, and millions of dollars are at stake. This C1 Business English lesson uses their story to build vocabulary for discussing data, innovation, progress and competition.

Project CETI’s progress shows what happens when AI meets a problem that was once too big to solve: huge amounts of data become patterns, and patterns become insight. For leaders, the lesson is that the advantage goes to organisations that collect the right data, test what they find against the real world, and stay focused on a long-term goal while others are still deciding whether to start.

The AI-Driven Race to Speak Whaleish
Charles Darwin, the most prominent evolutionary scientist of all time, believed that our ancestors may have learned to speak by copying the way birds sing. If he was right, human language began as something borrowed from another species. Now, thanks to rapid advances in AI technology, we may be on the brink of listening across the species barrier again, and this time the most promising voices are coming from the ocean.
Scientists around the world are now competing to understand what animals are saying, and there is serious money as well as scientific fame at stake. The Jeremy Coller Foundation, a charity focused on animal welfare, is offering a $10m investment to the first team that achieves real two-way communication with another species.
Research teams are studying everything from bird songs to marmoset monkeys, as well as whales and dolphins.
What has changed is the technology. AI models can now analyse millions of animal recordings and detect patterns that no human researcher could hear. Whales and dolphins are attracting the most attention because they pick up language by imitating others, and their sounds seem to follow rules and have a clear structure.
The best-known project is Project CETI (the Cetacean Translation Initiative), which is at the forefront of sperm whale translation. These whales “talk” in codas: short patterns of clicks, each one lasting around a millisecond. By training AI on thousands of these sequences, CETI researchers have found signs that whales belong to groups with their own dialects, use particular codas to address individuals, and take turns in conversation. The team has even pinpointed a click that may work like a punctuation mark.
The decoding process collects vast amounts of acoustic data using underwater microphones (hydrophones), often attached to drones and tagging devices that track whale movement. Once gathered, the data is fed into advanced machine learning algorithms, which sift through thousands of hours of clicks to find recurring patterns in structure. Clicks are also cross-referenced with observed whale behaviour, such as their movements, social situations, the presence of predators or food, and environmental changes, to guess at possible meanings or functions behind certain codas.
Alongside all the excitement, decoding whaleish may also open our eyes to the damage humans are doing to the whales’ world. Since the 1960s, shipping and mining have significantly increased background noise in the oceans. Near busy shipping lanes, whales often fall silent. Elsewhere, they change their dialects to cope with the noise, and they call out in distress near mining explosions.
Building on this potential new insight, CETI is determined to use its findings to influence marine protection policies and guide sustainable shipping in the oceans.
If we decode whale language, we could unlock the first true conversation between humans and another intelligent species—an evolutionary milestone. We might learn how whales pass on culture, coordinate activities across oceans, or even sense changes in the planet long before we do. Their vast deep-sea knowledge could even offer insight into improving ocean health. It is not only a translation, but a dialogue with another mind.

Sperm whales. CETI researchers have found signs that they use particular codas to address individuals.
Near busy shipping lanes they often fall silent, and elsewhere they change their dialects. This is because shipping and mining have significantly increased background noise in the oceans since the 1960s.
