The makers of a new app called Transcense say it can accurately translate in real time so the deaf and hard of hearing can take part in conversations with the hearing who do not know sign. While the app is being tested and is not yet available, the trio who created it are trying to raise funds through an Indiegogo campaign which you can see here. The guys behind the app include Thibault Duchemin, Pieter Doevendans and Skinner Cheng. Duchemin is a CODA and Cheng has been deaf he was a toddler.There's more information at the Transcense website here.
