Story summary

Project CETI researchers report that sperm whale vocalizations have a complex phonetic structure akin to human language.
The study, published in Proceedings B, describes a form of "alphabet" with vowel-like sounds resembling human speech patterns.
Lead author Gašper Beguš notes that meanings remain unclear, but the findings indicate a sophisticated communication system.
The team aims to decode about 20 unique expressions by 2031, expanding understanding of whale communication.
