Voice Carry Over caller with TTY

Voice Carry-Over (VCO)

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 Communications Assistant serves as the VCO caller's "ears" and types everything said to the VCO caller's TTY or VCO device. If an elderly person with progressive hearing loss has difficulty hearing over the phone, VCO may be the perfect communication solution for them.

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

How Does Voice Carry-Over Work?


Dial 877-877-1474 for automatic VCO call processing. Or dial 711 and notify the Communications Assistant that you are making a VCO call. Give the Communications Assistant the area code and telephone number of the person that you wish to call.


The mother, as the VCO user who
has a hearing loss speaks to her
son directly.  

After the VCO user says, "Go Ahead", it is her son's turn to respond.

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

The mother reads on a TTY screen or VCO device display what her son says.

Other Voice Carry-Over Services

The Communications Assistant specializes in all types of VCO calls, such as VCO to TTY, VCO to VCO, or 2-Line VCO.  Please specify the VCO call type to the Communications Assistant when placing the call.


The Communications Assistant will only type what the VCO user says to the TTY user being called. Whatever the TTY user types will go directly to the display of the VCO user's equipment for the VCO user to read. "GA" is needed for this type of call.


The Communications Assistant will serve as both parties' "ears", the communications assistant will type each parties spoken conversation. "GA" is needed for this type of call.

2-Line VCO

Two-line VCO allows a customer 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 or the need to use "GA."
