AI technology and advancements in recording devices are allowing researchers to listen to conversations outside of human hearing range, potentially enabling us to 'translate' animal sounds. The podcast explores topics such as infrasound, ultrasound, the unique codas of sperm whale families in the Eastern Caribbean, deciphering sperm whale communication, and the potential of AI in decoding and communicating with animals.

Quick takeaways
Sperm whales use codas to communicate within their families, but their exact meanings remain unknown, and AI technology could potentially help decipher their complex language.
AI has the potential to decode animal languages by mapping relationships between words and concepts, but understanding the unique worldview of different species poses a significant challenge.

Deciphering Sperm Whale Communication
Marine biologist Shane Gero studies sperm whale behavior off the coast of Dominica. Sperm whales communicate using patterns of clicks called codas, which Shane records using hydrophones. He has discovered that these codas serve as a Morse code-like sequence of communication within whale families. Different clans of whales have distinct codas, which allow for social bonding and identification. However, despite years of research, Shane has been unable to fully understand the meaning behind the whales' communication and hopes that AI technology can help unravel their language.
AI and Understanding Animal Communication
Aza Raskin, founder of Earth Species Project, aims to use AI to understand animal communication. By harnessing the power of transformers, which map relationships between words and concepts, AI can potentially decode animal languages. Aza believes that AI can align different languages, including those of animals, by quantifying the relationships between various components in communication. However, the challenge lies in perceiving and understanding the unique worldview of different species, as their mode of communication may differ significantly from human language.
The Potential of Two-Way Animal Communication
While AI may facilitate two-way communication with animals in the future, marine biologist Shane Gero, involved in Project SETI, emphasizes the need to first listen and understand animals. He believes that the value systems of both humans and animals likely overlap, making their communication essential. However, Karen Bakker, a professor of bioacoustics, cautions against overestimating our ability to complexly converse with other species in real-time through digital technology. She suggests that progress may focus on interpreting animal sounds more accurately to ensure minimal interference rather than full-blown translation.
A hardware revolution in recording devices and a software revolution in artificial intelligence is enabling researchers to listen in to all kinds of conversations outside the human hearing range, a field known as bioacoustics. Some scientists now believe these developments will also allow us to ‘translate’ animal sounds into human language. In a new season of Tech Tonic, FT innovation editor John Thornhill and series producer Persis Love ask whether we’re moving closer to being able to ‘speak whale’ or even to chat with bats.
