Real-time text (RTT) is a communication service that allows people who are deaf or hard of hearing to communicate with hearing people over the phone using text. RTT is a more advanced protocol than traditional teletypewriter (TTY) service, as it transmits both text and audio in real time. This allows for more natural and fluid conversations.
How does RTT work?
RTT uses a special type of phone line that can transmit both text and audio. When you make an RTT call, your iPhone will automatically detect if the other person’s phone is also RTT-enabled. If it is, the call will be placed in RTT mode.
To use RTT, simply type your message into the text field on your iPhone screen. Your message will be sent to the other person immediately, and you will be able to see their response on your screen as they type it. You can also continue to speak during the call, and your voice will be transmitted to the other person.
Benefits of using RTT
There are many benefits to using RTT, including:
- More natural and fluid conversations:RTT allows for more natural and fluid conversations than traditional TTY service, as both text and audio are transmitted in real time. This can be especially helpful for people who are deaf or hard of hearing, as it allows them to communicate more easily with hearing people.
- Greater access to communication:RTT is available on a wider range of devices than traditional TTY service, including iPhones, smartphones, and computers. This makes it easier for people who are deaf or hard of hearing to stay connected with friends, family, and colleagues.
