Voice Carry-Over (VCO) allows a caller with hearing loss to speak directly to a hearing person. When the hearing person speaks to a VCO caller the Communication Assistant (CA) serves as the VCO caller’s “ears” and types everything said to the VCO caller’s TTY or VCO phone. If an elderly person with progressive hearing loss has difficulty hearing over the phone, VCO is the perfect communication solution for them.

English-to-Spanish and Spanish-to-English translations are also available for VCO relay customers.

How Does VCO Relay Work?

  • 1

    The mother who has a hearing loss speaks to her son directly.

  • 2

    The son speaks to his mother, and the CA types everything the son says, word for word, to the mother.

  • 3

    The mother reads on a TTY screen what her son speaks.

Other VCO Features

The CA specializes in all types of VCO calls, such as VCO to TTY, VCO to VCO, or Two-Line VCO. With this service, you do not have to specify your call type to the CA.

VCO to TTY

The CA types what the VCO user says to the TTY user. Whatever the TTY user types goes directly to the VCO user’s TTY or text display equipment to be read.

VCO to VCO

The CA serves as both parties’ “ears”, typing what is said on both ends of the call.

Two-Line VCO

Two-line VCO allows a person with two telephone lines to use one line for speaking directly to a hearing person while the other line is used to receive the hearing person’s typed responses at the same time. This feature provides a more natural flow of conversation without the pauses of single-line calls.
