Operator typing on a TTY

What is a TTY 
and
What Equipment is Available?















How is communication possible among people who are deaf, hard of hearing, don’t speak or have speech that is difficult to hear? The most common method of communication via telephone among the deaf and hard of hearing is a TTY (teletypewriter); or a TDD which is a telecommunication device for the deaf. A Telephone Typewriter (TTY) is a text-based device that enables people who are deaf or have a speech impairment to communicate via the telephone line. By using the TTY keyboard two people can type messages to one another over a telephone line or via the Sprint Relay Service. The conversation appears on a small display located on the phone.

How do TTYs and TDDs work?
The user types a message that appears on the screen of the recipient. The recipient responds in the same manner throughout the duration of the conversation. So what happens when a hearing person tries to call someone who does not hear? The hearing person dials the Sprint relay service that provides service to the deaf community of Utah. The operator will connect the hearing person with the deaf individual. The operator then relays the information given by both parties.
