VCO

Voice Carry Over (VCO)
VCO allows deaf or hard-of-hearing people who prefer to use their own voice to speak directly to the party they are calling. The CA will type the voice responses back to the VCO user who reads the typed message across the TTY screen. Relay South Dakota also provides VCO with privacy, where the CA will not hear the VCO caller speaking through TRS.

VCO to HCO
VCO users can communicate with HCO users through Relay South Dakota. The VCO user speaks directly to the HCO user and the HCO user types their response directly to the VCO user.

VCO to TTY
VCO and TTY users can communicate with each other through Relay South Dakota. The VCO caller uses his/her voice to speak, which is typed by the CA, to the TTY user. The TTY user types directly to the VCO user, who reads the typed message across the TTY screen, with no CA interaction.

VCO to VCO
VCO users can communicate with other VCO users through Relay South Dakota. The CA listens to each VCO users' spoken words and types for the parties at both ends.

Two-Line VCO
Two-line VCO provides a "real-time" conversation between the VCO and Voice users. With two telephone lines (one with conference calling capabilities) the VCO user speaks directly to the Voice user on one line while the other line is used to receive the CA's typed responses from the Voice caller. This occurs without saying "GA" and allows two-way uninterrupted conversation; it provides a more natural flow of conversation.
