AI is advancing the understanding of animal communication, revealing complex vocalizations in species like bonobos and whales that challenge human language uniqueness.

Research into animal communication has revealed surprising complexities, particularly in species such as bonobos and whales. A study led by Mélissa Berthet observed bonobos in the Congo combining calls to form intricate phrases, suggesting a level of compositionality previously thought unique to humans. AI tools are increasingly employed to analyze and interpret these vocalizations, enabling researchers to uncover patterns that may indicate a form of language. For instance, sperm whales have been found to use a phonetic system with distinct sound patterns. This growing body of evidence challenges traditional definitions of language and raises questions about the cognitive abilities of non-human animals. While some features of human language remain unobserved in animals, the research suggests that the line between human and animal communication may be less distinct than previously believed.
