A new study published in Proceedings of the Royal Society B reports that sperm whales produce vowel-like sounds within their click sequences, with structural parallels to human language phonology — including length distinctions resembling those in Latin and Arabic. While the findings from Project CETI mark a significant step in understanding cetacean communication, skeptics argue that imposing human linguistic frameworks on whale acoustics risks obscuring what is genuinely distinctive about how these animals interact.
