What Is a TTY Adapter?
A Tele-Typewriter, or TTY device, is a machine for the deaf or hard of hearing designed to allow text-based communication over phone lines. Most TTY devices utilize a small screen and a keyboard that connects to a phone line and allow users to type conversations and read responses. In order for these calls to occur, TTY devices must be available on both sides of the conversation. In the case of many cell phones, TTY adapters may be used to allow communication between the cell phone and a receiving TTY device. TTY adapters may also be used to attach third-party wired headsets to cell phones.
