Real-time text (RTT) is a smartphone communication feature that transmits audio as you type text to help users with speech and hearing difficulties.
RTT is a more advanced protocol that sends audio along with the text. The Phone app on the iPhone
includes built-in Software RTT and TTY, so no additional devices are required.

3 Steps To Turn Rtt Off On Your iPhone:
The RTT feature is critical in ensuring a smooth conversation between iPhone users who are deaf or hard of hearing. You can make a regular call with or without RTT mode, and you can disable it if you don’t need it.
Removing the RTT from your iPhone is simple, and we’ve broken it down into three simple steps that we’ve outlined below. Examine it out:
Step 1: Navigate To The Accessibility Tab In Settings
- Locate and tap the Settings app from your iPhone’s Home Screen. Scroll to the bottom and select “Accessibility.”
- Alternatively, you can access this setting via the App Library or by following the instructions below.
- Navigate to Settings > “General” and then to “Accessibility.”
Step 2: Select RTT/TTY And Deactivate The Switch
- Scroll down to the “Hearing” section and select “RTT.”
- If your iPhone does not have RTT, select “RTT/TTY.”
- The “Software RTT” option is at the top of the RTT/TTY screen, and “Software TTY” is below.
- Turn on the Software RTT toggle.
- If your iPhone lacks the Software RTT, you will instead find the “Software RTT/TTY.”
- Tap to turn off the toggle, as well as the Software TTY. When the color is green, the switch is turned on, and when it is gray, it is turned off.
Step 3: Close The Window
You have successfully turned off RTT on your iPhone. You can now leave the screen and call or text as usual.
