Captioned Telephone Service is used by persons with a hearing disability but some residual hearing. It uses a special telephone that has a text screen to display captions of what the other party to the conversation is saying. A captioned telephone allows the user, on one line, to speak to the called party and to simultaneously listen to the other party and read captions of what the other party is saying. There is a “two-line” version of captioned telephone service that offers additional features, such as call-waiting, *69, call forwarding, and direct dialing for 911 emergency service. Unlike traditional TRS (where the CA types what the called party says), the CA repeats or re-voices what the called party says. Speech recognition technology automatically transcribes the CA’s voice into text, which is then transmitted directly to the user’s captioned telephone text display.
