People with a speech disability, or those who use a voice synthesizer, can use their own voice on a STS relay call. The Communications Assistant who is specially trained to understand unique speech patterns, repeats the words exactly as they are spoken to their caller.

How Does STS Relay Work?

  • 1

    The STS user speaks directly to the other party while the Communications Assistant listens.


  • 2

    The Communications Assistant repeats the STS user’s spoken words to the other party as needed for clarity.


  • 3

    The other party talks directly to the STS user.


STS Call Setup

In order to speed up the set-up of the call, Relay Colorado now offers STS Call Setup. Now, you can e-mail call instructions or information 2 to 24 hours prior to the call. This can include information such as the number to be dialed, the name of the person being called, any special instructions and the nature of the call, or anything that makes it easier for you to complete the call.
