See Telecoil. This term was originally used in analog aids where there was a separate switch to turn on the telecoil.

Telecommunication Device for the Deaf. (See Teletype.)

A tiny coil of wire built into many hearing aids that allows the hearing aid to pick up the magnetic fields emitted by telephones, various assistive listening devices, or induction room loops. Sometimes referred to as “t-switch” or “t-coil.”

This term has fallen out of favor as the Deaf community never liked it. They use TTY, the abbreviation for teletype instead. (See Teletype.)

A telecommunication system that uses operators (called Communications Assistants [CA]) to facilitate telephone calls to or from people who are deaf or have limited hearing and also people with speech disabilities. This includes text to voice (TTY), Voice Carry Over (VCO), Captioned Telephone Service, Video Relay Service (VRS) and several other modes.
