Are you having trouble using the telephone due to a hearing or speech disability?
Relay is a free telephone service that uses specially trained communications assistants to facilitate telephone calls between people with hearing and speech disabilities and other individuals. Calls can be made to anywhere in the world, 24 hours a day, 365 days a year. All calls are completely confidential. To make a relay call dial 7-1-1. Once connected to the relay service, tell the communications assistant the type of relay call you wish to make. Or, you may dial the specific toll-free number for the type of relay service.
Emergency Assistance: TTY callers should dial 911 directly in an emergency. All 911 centers are equipped to handle TTY calls.
Internet Protocol Captioned Telephone Service (IP CTS) Internet-based forms of CTS are available for those who would like to use CTS on a computer, tablet, or smartphone. Go to: www.fcc.gov/consumers/guides/internet-protocol-ip-captioned-telephone-service.
Computer (ASCII): Computer users can access Minnesota Relay. Set your communications software to the following protocols: speeds ranging from 300 to 2400; 8 Bits; No Parity; 1 Stop Bit; Full Duplex. When calling at a rate of 300 or below, follow the above using Half Duplex.
Hearing Carry Over (HCO): HCO allows a person who can hear clearly but who has very limited or no speech capability to make phone calls. Using a special text telephone, you type your conversation for the relay communications assistant to read to the other person, and listen directly to the other person’s response.
Hearing User: A hearing person may use a standard telephone or mobile phone to place a relay call and speak with a person who is deaf, hard of hearing, or speech disabled.
Internet Protocol (IP) Relay IP Relay combines text-based relay service with the ease of the Internet – no need for a TTY. You can make your relay call using a computer, laptop, tablet, or smartphone. Go to: www.sprintrelay.com.
Spanish Relay: Spanish speaking persons with a hearing or speech disability are able to make relay calls. This is not a translation service – both parties must speak Spanish, and at least one party must have a hearing or speech disability.
Speech-to-Speech (STS): STS allows a person who has difficulty speaking or being understood on the phone to communicate using his or her own voice or voice synthesizer. The communications assistant re-voices your words so that the other person on the call can understand them, and the other person speaks directly to you.
Text Telephone (TTY): This service allows a person who is deaf, deafblind, or speech disabled to use a TTY to communicate with the other person on the call.
Video Relay Service (VRS) VRS allows a person who uses American Sign Language (ASL) to communicate over the phone. The VRS user connects to the relay communications assistant via an Internet-enabled device with a video camera. The communications assistant relays the conversation back and forth between the parties – in ASL with the VRS user and by voice with the called party. Go to: www.fcc.gov/consumers/guides/video-relay-services.
Voice Carry Over (VCO): VCO allows a person with a hearing disability, but who wants to use his or her own voice, to speak directly to the other party. The communications assistant then types the other party’s response, which is displayed on the VCO user’s text telephone.
You may also file a complaint with the Federal Communications Commission:
ASL via VP: 1-844-432-2275
