Marine biologist David Gruber introduces Project CETI: a team of scientists, linguists and AI specialists hoping to decode sperm whale language. Using noninvasive robots and a machine-learning algorithm to collect and analyze millions of sperm whale vocalizations known as coda, the team aims to demystify the communication structures and dialects of these majestic creatures — and possibly even crack the interspecies communication code. (This ambitious plan is a part of the Audacious Project, TED's initiative to inspire and fund global change.)
