The sperm whale 'phonetic alphabet' revealed by AI
Researchers studying sperm whale communication have found structures resembling human language, indicating advanced communication skills. Analysis of 9,000 recordings revealed 156 distinct codas forming a complex communication system akin to human phonetics. This discovery suggests sperm whales possess a sophisticated communication capacity beyond previous understanding, potentially involving combinatorial coding similar to human language. The study emphasizes the importance of further research to safeguard these marine mammals from environmental threats.

Researchers studying sperm whale communication have uncovered structures similar to human language, suggesting sophisticated communication abilities in these marine mammals. Sperm whales, known for their complex social behavior, communicate using rhythmic sequences of clicks called codas. By analyzing nearly 9,000 recordings, researchers identified 156 distinct codas, revealing a "sperm whale phonetic alphabet" akin to human language phonemes. These codas consist of rapid-fire clicks with variations in speed and delivery, suggesting a richer information capacity than previously thought. The study also suggests the potential for combinatorial coding in sperm whale vocalizations, similar to the linguistic phenomenon of duality of patterning in human language. While this research represents a significant step towards understanding sperm whale communication, experts caution against an anthropocentric focus on language. The findings highlight the complexity of sperm whale communication and the need for further exploration to protect these vulnerable marine mammals facing threats like climate change and human activities.
