Captioned Telephone Service (CTS): CTS allows people who are hard of hearing to see word-for-word captions of their telephone conversations (like TV captioning). Requires special equipment.
Text-to-Voice (TTY): A person who is deaf, hard of hearing or speech disabled can use TTY to communicate with the other person on a call. Requires special equipment.
Speech-to-Speech (STS): The communications assistant (CA) revoices the words of the person with a speech disability so the other person on the call can understand them.
Computer (ASCII): Computer users can also access Telecom Relay Services. Set your communications software to the following protocols: speeds ranging from 300 to 2400 baud; 8 bits; No Parity; 1 Stop Bit; Full Duplex. (When calling at a rate of 300 baud or below, follow the above using Half Duplex.) Requires special equipment.
Hearing Carry Over (HCO): The HCO user types his or her conversation for the CA to read to the other person and listens directly to the other person's response. Requires a special telephone.
Voice Carry Over (VCO): VCO allows someone with difficulty hearing on the phone to voice their conversations directly to the other person on the call. The CA then types the other person's response to the VCO user. Requires a special telephone.
Voice Relay Service (VRS): VRS allows a person whose primary language is American Sign Language (ASL) to use a television or Internet-enabled device with a video camera to communicate with the CA in ASL. The CA speaks what is signed to the called party and signs the called party's response back to the caller.
Internet Protocol Relay Service (IP Relay): The Internet helps facilitate IP relay conversations, which allow someone with a hearing or speech disability to use their computer or web-enabled device to communicate by phone with hearing persons.
900 Pay-Per-Call Services: This option allows relay users to connect to any pay-per-call service.
Spanish Relay: These relay calls enable conversations between a Spanish-speaking person with a hearing or speech disability and someone else who speaks Spanish.
Internet Protocol Captioned Telephone Service (IP CTS): This service is ideal for someone with hearing loss, but can use his or her own voice and has some residual hearing. The person can speak directly to the called party and then also listen (to the extent possible) while simultaneously reading captions of what the other party is saying.
