Global Speech Rhythm: Humans Naturally Chunk Talk Every 1.6 Seconds
A major cross-linguistic study has found that human speech follows a universal rhythm, with intonation units—the musical, prosodic beats that structure speech—appearing roughly every 1.6 seconds across languages. The finding suggests that, despite the astonishing diversity of world languages, our everyday conversations are paced by a shared cognitive tempo that ties language to brain activity. For Thai readers, the news resonates beyond linguistics: it touches how we teach, how we learn, how clinicians help people communicate, and how the fast-growing field of language technology could better mirror human speech.
