Researchers find shared acoustic patterns in human speech and birdsong

A study published in Science reveals that human speech and song share recurring acoustic patterns with birdsong across hundreds of species. Researchers led by McGill University analyzed over 74,500 bird syllables from 367 different species and compared them to human vocalizations across 52 languages.

The findings indicate that both humans and birds exhibit similar statistical tendencies, including smaller pitch changes between sounds, relatively regular timing, and lengthened phrase endings. These patterns were observed in both birds that learn their songs through imitation and those whose vocalizations develop without such learning.

While the study identifies these universal acoustic organizations, researchers noted that the similarities do not imply that birds possess human-like language or understand music in the same way. Instead, the shared patterns may be a result of physical production constraints, suggesting that the way bodies produce sound may help organize vocal communication across diverse species.
