2016-2017 WINNERS

Four seventh graders from the Talented and Gifted (TAG) School won the 2017 Guppy Tank Challenge with their innovative app, Delta Speech. Inspired by the opportunity to solve communication problems for businesses, the students designed an app that allows individuals and groups to translate words and sentences. Delta Speech facilitates communication among those who speak different languages.
Guppy Tank’s 2016 winners hailed from P.S./I.S. 224. Their app, Dolphin, is an assistive communication program designed to aid non-verbal children with communication. By pushing a button and choosing a pre-programmed phrase transmitted through a mobile phone speaker, the user can efficiently communicate with others. Kim Kelleher, publisher of WIRED, cast the tie-breaking vote and declared Dolphin’s creators the winners of Guppy Tank 2016. As Ms. Kelleher indicated, Dolphin has the potential to transform communication for special needs children across the world.
