Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Current bioacoustic and ethological research indicates that animal vocalizations are not fully understood, as researchers still grapple with significant gaps in decoding semantics, syntax, and complex contextual patterns.

The analysis

The claim states that certain animal vocal languages are fully understood by researchers. The retrieved literature clearly contradicts this: paper [0] outlines persistent unsolved problems in computational bioacoustics, paper [1] notes that nonhuman primate vocal sequences lack semantics and syntax entirely, and paper [8] highlights the interpretive and methodological challenges in interspecies communication. No papers support the idea of complete understanding. Therefore, the evidence decisively refutes the claim.

Paper [1] notes that nonhuman primate vocal sequences lack syntax, semantics, and phonology, ruling out full human-like language understanding.

Paper [8] discusses the ethical and methodological challenges of interspecies communication, noting the risk of misclassification and emphasizing that meaning requires careful contextualization rather than full fluent translation.
