Born to deaf parents, Thibault Duchemin, the start-up who dreams of a “100% accessible” world

The Oscar winners made him jump for joy. “This is the first time in thirty-five years that a deaf person has been rewarded”, applauds Thibault Duchemin, evoking the distinction of best actor for a supporting role obtained by Troy Kotsur, Wednesday March 27, in Los Angeles. The Hollywood Academy also awarded the Best Picture Oscar to CODA, which tells the story of a family of deaf fishermen from New England, tossed about in the middle of a social conflict, in the general indifference.

CODA, it is not very well known in France, but it is the term used in the United States: “Child of Deaf Adult”, or child who comes from a deaf family”, explains Thibault, 30, living in San Francisco since 2012 and himself “born CODA”, in Paris. “My parents and my sister are deaf.

Ava (or Audio Visual Application): a voice recognition application with instant subtitling, which allows hearing-impaired people to follow what is said in their daily life: family meals, work meetings, etc.

“We were an essential device”

The founders are very proud. The app was used on the set of CODA, to facilitate exchanges between the technical team, the director and the deaf actors, Troy Kotsur and Marlee Matlin. “Understanding group conversations is an absolutely essential need”, emphasizes Thibault. Its voice algorithms are able to transcribe the sentences spoken by the different interlocutors in less than a second. The participants follow the subtitling on their smartphone, including the tit for tat exchanges thanks to an adapted visual: each is identified by a color.
