Americans with Disabilities Act of 1990
Title IV also led every state in the U.S. to create Telecommunications Relay Services (TRS), such as STS relay.  STS stands for Speech-to-Speech.  It was created for people who have speaking problems.  STS relay operators listen to what the person is saying and repeats it in a clear voice to make it easier for the other person to understand. Today, many calls that use TRS are made over the Internet by consumers who use broadband connections. Some are Video Relay Service (VRS) calls, while others are text calls.  Either way, communication assistants translate between the signed or typed words of a consumer and the spoken words of others.  In 2006, according to the Federal Communications Commission (FCC), VRS calls averaged two million minutes a month.
