Your smartphone is the most useful tool you carry with you on a daily basis. This is why accessibility features are so important; they ensure that we all have access to the features of our phones when we need them.
Historically, Android has done an excellent job of integrating accessibility features into its platform. RTT calls are one of these features. If you or a loved one is deaf, hard of hearing or speech impaired, RTT can be a game changer.
What does RTT call mean in Android?
RTT stands for Real Time Text. Calling is a type of call that allows you to communicate using text instead of talking. It shows the real-time keystrokes of each person in an RTT call, so there is no need for a Send button (typically). When a person finishes communicating, they stop writing, just as they stop talking when they finish talking on the phone.
What is the purpose of RTT calls in Android?
RTT Calling allows people with hearing and speech difficulties to have non-verbal conversations in real time. The concept of RTT Calling is to replace coughing, throat clearing, and other complexities that arise from vocal human communication with real-time keystrokes that indicate a person’s cognitive process in real time.
The experience is also similar to a phone call. Watching someone compose, review, and finalize a letter to the other party feels intimate and, most importantly, human. This allows Android users who are deaf or hard of hearing to experience the texting equivalent of an intimate and confidential phone conversation.
On Android, how do you enable RTT calls?
If your Android phone supports RTT calling, you can usually enable it in the Accessibility section of the Settings app. On a Pixel 7, for example, open the Settings app, tap Accessibility, then tap Real-time Text (RTT).
When RTT calling is enabled, you can choose how visible the real-time text (RTT) button should be:
- Not visible: Allows RTT calls while hiding the Call button.
- Visible during call: During a call, the RTT button is displayed.
- Always visible: During a call, the RTT button appears on the keyboard.
How to make an RTT call on Android
To make an RTT call, make sure the RTT button visibility is set to Always on top. On Android, open the Contacts app, the Phone app, or one of several third-party dialer apps and dial a number. Except this time, press the RTT button to convert the call to an RTT call.
If the RTT button does not appear, select More (or a similar option).
The other party will be invited to join the RTT call while you dial. When you join, every keystroke you make will be visible on the screen. It’s like watching a live keylogger. When you are done with the RTT call, just like with a voice call, tap the End Call button.
While roaming, RTT calls are not available.
How to switch from a voice call to an RTT call in real time on Android
To switch from a voice call to an RTT call on Android (or vice versa), make sure the RTT button visibility is set to Always visible or Visible during call. During a call, tap the RTT button at the bottom of the call screen or press More to locate and tap the RTT button. This will convert the voice call to an RTT call.
Can you contact emergency services on Android using RTT?
Even if there is no signal, your phone can call emergency services. It should come as no surprise that you can communicate with 911 on Android using RTT. Just make sure you have previously set up RTT calling before placing the call. Contact your local emergency services to find out if they support RTT calls.
