TTY (teletypewriter)

A TTY (teletypewriter) is a communication device that allows people who are deaf, hard of hearing, or have speech impairments to converse via text. It connects through a telephone line, enabling users to type messages back and forth in real-time, similar to instant messaging. TTYs typically have a keyboard and a small screen or printout, making it possible to read and send messages quickly. They are essential tools for accessible communication, ensuring individuals with hearing or speech challenges can connect effectively with others over the phone or similar networks.
