Captioned Telephone

A telecommunications device that displays real-time captions of what the other party is saying during a phone call, enabling people who are hard of hearing to read the conversation while also listening. Captions are generated by a trained communications assistant who re-voices the caller's speech through a speech recognition engine, or increasingly through automated speech recognition. Captioned telephone services are available in the United States at no extra charge through the Telecommunications Relay Service program mandated by the Americans with Disabilities Act.
