If you have an iPhone, you may have heard of the RTT (Real-time Text) feature. This is a great accessibility feature that helps people with speech and hearing difficulties communicate during calls.
The feature uses a more advanced protocol that instantly transmits your text message to the recipient while you’re typing it. You can even send audio simultaneously!
What is RTT?
What does RTT mean on an iPhone?
Real-time text (RTT) is a feature that lets you send messages instantly during a call. It’s a valuable accessibility tool for those with hearing or speech disabilities, and it eliminates the need for expensive, specialized hardware like teletypewriters.
To use it, start a phone call and select either RTT/TTY or TTY in the Phone app’s menu. You’ll receive a message box to enter your text, much like SMS. If you’ve turned on Send Immediately in Settings, your recipient will see every character as you type it.
Incoming calls will have an RTT icon next to them, and outgoing calls will have a TTY icon. To review a past RTT or TTY call, tap Recents.
A quick note: RTT and TTY support aren’t available in all countries or with all carriers, and standard voice call rates apply for Software RTT/TTY and Hardware TTY.
For those who have an iPhone running iOS 11, tap the RTT or TTY toggle under the ‘Hearing’ section of your phone’s Settings. You’ll find both RTT and TTY under the ‘Accessibility’ tab as well.
Move the Software RTT toggle to on if it’s green and move the Software TTY toggle to off if it’s gray. You can also turn on or off the Hardware TTY switch.
Once you have it enabled, you can make and receive calls using the RTT protocol, and the text of your RTT calls is saved for you to read later. You can also search for previous conversations to look at what was said during the call.
It’s worth noting that while RTT can transcribe voice to text, it doesn’t work with the built-in microphone, so you won’t hear any audio during your RTT call. Additionally, you won’t be able to use the Continuity features that other callers can enjoy.
How does RTT work?
RTT is a great accessibility feature that allows hearing and speech impaired users to make and receive phone calls without having to use specialized hardware. It is not available in every country, but if your telecommunications carrier supports RTT, you can use it with an iPhone running iOS 10 or later.
You can enable and use RTT on your iPhone by turning on the feature in Settings. You can also turn it off if you don’t need to use it.
When you enable RTT in Settings, your iPhone sends characters instantly as you type them, and your recipient sees each character you type. If you don’t want this to happen, turn off the toggle for Send Immediately.
Once your RTT is enabled, you can place and receive RTT calls from the Phone app or FaceTime. You can even start a RTT call from the Contacts app. If your telecommunications carrier supports RTT, your iPhone will automatically switch to the protocol when you make or receive a phone call that uses it.
To make an RTT call, tap the phone number of the person you want to call. You can then tap RTT Call or RTT Relay to start the call. You can also start a RTT call from the Contacts apps on your Mac or iPad.
If you’re a TTY user, you can connect to an external TTY device using the iPhone’s Bluetooth or Wi-Fi capabilities. To do this, go to Settings > Accessibility and enable Hardware TTY.
RTT is an advanced accessibility protocol that transmits text messages over IP-based networks, which makes it more reliable than TTY. Unlike TTY, which is based on an older technology and requires specialized hardware, RTT can be used by everyone and doesn’t require any special hardware.
There are many situations where RTT can be useful, from communicating important information in noisy environments to passing confidential data when you don’t have a phone. It’s a useful tool for the hearing and speech impaired, as well as anyone who needs to communicate in a silent environment.
If you’re using a TTY, you can view a transcript of a prior RTT or TTY call in the Phone app by tapping Recents. You’ll see a typewriter symbol next to each call, and you can tap it to get a transcription of the conversation.
How do I turn off RTT on my Android?
RTT, or real-time texting, is a feature that helps those with hearing or speech impairments send text messages to each other during phone calls. While some people find this helpful, others don’t want to use it.
Some Android phones allow you to disable the RTT feature without needing to uninstall the application. The process is simple and requires just a few steps.
First, open the Settings app on your phone and select Calling. You should see a button that says “RTT.” This should display a toggle. Tap the switch to turn it off.
Another option is to install a third-party dialer app. This will allow you to completely disable the RTT feature and ensure that any callers you receive have a phone that doesn’t support it.
A third option is to contact your network provider. They may be able to disable the RTT feature for you or point you in the right direction for more information.
You can also try to restart your phone. This can help fix any issues with the real-time text application, which might be causing the RTT to stay on. If that doesn’t work, you might need to delete and reinstall the app to get it working again.
What is the difference between RTT and TTY?
RTT is a feature that allows you to send text messages during a phone call. This feature is available with Xfinity Mobile and a compatible cellular connection. It can also be used with a TTY device. You can even find transcripts of previous calls using this feature.
RTT uses IP-based wireless technology on networks that support it, and is a new accessibility solution for deaf and hard of hearing people. Unlike standard text messaging applications, which require users to type out a message and then hit send, RTT automatically transmits the text as it is being written, character by character.
Another advantage of RTT is that it is easier for users to communicate with each other during a phone call. It eliminates the need to purchase specialized devices like TTYs, which require users to take turns on who can send and receive text. In addition, RTT is more reliable over IP networks compared to TTYs – it will not cause drop-offs or garbling, and can use the full international character set.
Moreover, RTT can facilitate the transition to Next Generation 911 (NG911)–the next version of emergency services that will allow voice, video and text communication to public safety answering points. NG911 standards include support for RTT, as well as backward compatibility with TTY, which will help ensure that PSAPs can continue to serve those with disabilities and other users who need access to these services.
For those with hearing and speech disabilities, RTT will also enable users to send text during a phone call, eliminating the need for them to buy specialized TTYs. This feature will also allow users to have a more natural, bi-directional flow of conversation during a call compared to voice communications, which can be confusing and confusing for users who are unfamiliar with the language.
To make the transition to RTT as effective and seamless as possible, the Commission adopts rules allowing IP-based wireless providers and manufacturers (covered entities) that provide wireless voice services, subject to the performance objectives of parts 6, 7, 14, 20 and 64 of its rules, to support RTT in place of TTY technology. These rule changes are intended to address the unique needs of the disability community by allowing them to select off-the-shelf IP-based wireless devices for their communication needs without having to rely on a specialized TTY device that may not be accessible or familiar to them.
