Hearing carry-over—or HCO—is ideal for people who are able to hear, but have difficulty speaking over the phone. The HCO user types his or her side of the conversation, using a TTY or similar device, and the Communications Assistant (CA) voices the typed words to the other person. When the other person speaks, the HCO user listens directly to what is being said.
This feature gives HCO users additional control and allows them to have an interactive conversation without the use of Relay commands such as “GA” (Go Ahead) and “SK” (Stop Keying). The CA will not identify the Relay and will only voice the typed text of the HCO user to the person he/she has called. 2-Line HCO requires two telephone lines, one of which must have 3-way conferencing capabilities.
(A Georgia Relay Customer Profile is highly recommended for HCO users and will streamline the following steps.)
