Phone Technology 
Breaks Communication Barriers
TTY/TDD
Individuals with auditory (deaf/hard-of-hearing) and/or speech disabilities often communicate by telephone with a Teletypewriter (TTY) or Telecommunications Device for the Deaf (TDD).  Although signifying the same assistive technology, TTY is the most inclusive and widely accepted term.  
A basic TTY consists of a keyboard, display screen, and modem that facilitate the exchange of text messages rather than voice over standard telephone lines.

TELECOMMUNICATION RELAY SERVICE
The national Telecommunication Relay Service (TRS) provides two-way translation between individuals using a TTY (typed text) and a standard telephone.  TRS operators, called communications assistants, translate the spoken words of the individual using a standard telephone into text for individuals using TTYs (e.g., someone who is deaf/hard-of-hearing and/or has a speech disability) - and vice versa.
Mandated by the Americans with Disabilities Act (ADA), the service is FREE and always available (i.e., 24 hours a day/7 days a week) throughout the nation, Puerto Rico, and U.S. territories.

SPEECH-TO-SPEECH RELAY SERVICE	
Speech-to-Speech (STS) Relay Service operators, also called communications assistants, specialize in language recognition and are familiar with many different speech patterns.  They provide telecommunications assistance for individuals with speech disabilities.  As an individual with a speech disability talks, the communications assistant repeats the individual with a speech disability's message verbatim to the other party of the phone call.
