Speech-To-Speech (STS)

STS Relay is the Speech To Speech Relay Service available to any telephone callers or callees with speech disability and to those who wish to talk with them.

Speech to Speech (STS) exists for people with mild speech disabilities. A special STS Telecommunication Relay Service (TRS) operator re-voices what the speech-disabled person says. STS is often used in combination with VCO for the Deaf who have somewhat understandable speech.
