  • When the phone rings, do you feel stressed? 

  • Are you worried that you won’t understand the person calling you?

  • Do you look around to see if someone else can answer the phone?


Well, worry no more!

Captioned Telephone Service allows you to answer your calls with confidence. You can relax and enjoy your conversations again! With your CapTel phone, your calls will be captioned and you won’t have to make wild guesses as to what the caller is saying. Captioned Telephone Service allows you to LISTEN and READ captions of everything your caller says during your phone conversations. Don't miss another word!



CapTel® is short for captioned telephone. A person with hearing loss places a call in the same way as dialing a traditional phone. CapTel uses voice-recognition technology to display verbatim captions of the other party's conversation on the telephone’s screen, allowing the person with hearing loss to hear and read all comments.
