TTY

TTY, or teletypewriter, is a device that enables people who are deaf, hard of hearing, or have speech impairments to communicate over the phone. It works by allowing users to type messages that are transmitted to another TTY device, where the recipient reads the text and can reply by typing. Modern TTY systems often connect via special phone lines or digital networks, facilitating real-time text conversations. Essentially, TTY turns typing into a communication method over traditional telephone infrastructure, ensuring accessibility for those with hearing or speech difficulties.
