Humans are making progress on decoding the language of whales. They seem to have something that functions roughly like vowels.

Researchers are making progress in decoding the communication systems of whales, with recent findings suggesting their vocalizations contain structural elements that function similarly to vowels in human language. This points to a more complex, potentially rule-governed communication system in cetaceans than previously understood. The work is part of broader efforts, including projects like CETI (Cetacean Translation Initiative), to use AI and machine learning to analyze and interpret whale calls at scale.
