A CapTel phone user places a call in the same way as dialing a traditional phone. As he or she dials, the CapTel phone automatically connects to a captioning service. When the other party answers, the CapTel phone user hears everything the other party says, just like a traditional call.


Behind the scenes, a specially trained operator at the CapTel Captioning Service transcribes everything the other party says into written text, using the very latest in voice-recognition technology. The written text appears on a bright, easy-to-read display window built into the CapTel phone. The captions appear almost simultaneously with the spoken word, allowing the CapTel phone user to understand everything that is said either by hearing it or by reading it.


  • A Captioned Telephone (CapTel): A specialized telephone designed to interact with the CapTel Captioning Service to display captions. The telephone does not, by itself, translate spoken words into written captions. It can also be used as a traditional amplified telephone, by turning off the captions feature.


  • CapTel Captioning Service: The CapTel Captioning Service transcribes the other party's spoken words into written captions, which appear on the CapTel phone display. The cost of the captioning service is covered by Telecommunications Relay Service (TRS) funds as part of Title IV of the Americans with Disabilities Act (ADA).

FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. IP Captioned Telephone Service may use a live operator. The operator generates captions of what the other party to the call says. These captions are then sent to your phone. There is a cost for each minute of captions generated, paid from a federally administered fund. No cost is passed on to the CapTel user for using the service.
