Like everyone, the Deaf use their mobile phones for everything – from web browsing to Candy Crush. They can’t, however, answer phone calls. But things are changing, thanks to ‘Say It With Signs’ – an app that combines voice-to-text and text-to-sign technology. So a deaf person can now have a phone call conversation with a hearing person. This helps especially in situations where the hearing person can’t text – i.e. while driving.
