New research analyzing 2014–2018 recordings of Caribbean sperm whales finds signs of a highly complex phonetic system in their calls, including vowel-like patterns and diphthongs. Using GANs within Project CETI, scientists identify vowels differentiated by inter-click intervals and suggest these whales may have a developing vocabulary, with a goal to interpret around 20 expressions (e.g., diving, sleeping) by 2031.
Sperm whales’ codas show vowel-like differences and tonal patterns arranged in multi-layered structures that closely resemble human phonology, suggesting parallel evolution of language-like signals. The findings from Project CETI and UC Berkeley researchers, published in Proceedings B, push forward the goal of understanding whale speech and eventually enabling interspecies communication, though significant work and funding remain.
Researchers captured the first recorded birth of a sperm whale, showing a coordinated group response as multiple females surround and assist the mother and newborn, suggesting a shared social role within the pod and challenging previous notions of whale individuality; the findings, published in Science based on long-term CETI observations, imply complex intelligence and cultural transmission in whale societies.
Researchers filming off Dominica captured a rare birth of a sperm whale in which surrounding females—related and unrelated—cooperated to support the laboring mother and calf, a first documented instance of birth assistance in non-primates, with vocal changes suggesting coordinated care.
Scientists documented one of the most detailed wild observations of a sperm whale birth, revealing cooperative female behavior as they protect the newborn calf and help it reach water safety, with observations tied to Project CETI.
Field observers off Dominica in July 2023 captured an 11-whale group from two matrilines coordinating a calf’s birth and postnatal care, with a core quartet lifting and maintaining the newborn at the surface for breathing while the wider group stayed cohesive; the study, aided by machine learning and computer vision to track individuals, provides rare quantitative evidence of allocare and complex sociality in sperm whales and was published in Science Advances.
