“Its clear social purpose, thoughtful application of AI and ability to remove a barrier many people encounter every day made it an outstanding example of AI for Good.”
Built by the person who needed it
“I’m deaf, and what I wanted was an app on my own phone that kept up with me, not a special device that made the call about my hearing.”
Olivier Jeannel has been deaf since age two. At 33, he started Rogervoice in 2014 because no one was building the product he needed. Today it’s an FCC-certified service that has carried more than 12 million captioned calls.
