In order to help those folks who have trouble communicating verbally, cell phones now include a feature called “Real-time Text (RTT)” that sends out the audio as the user types, greatly improving their ability to interact.
Keep it disabled on your mobile device for routine phone calls, if you don’t plan on using it. But exactly how do you accomplish this? Below, I’ll go into greater depth about this topic. So keep reading, if you want to know how to get rid of “RTT” on your smartphone immediately.
RTT/TTY Feature
Real-time Text (RTT) is a smart mobile device accessibility feature that enables both making and receiving calls, without utilizing the device’s built-in microphone and speaker. It can transcribe speech-to-text as well as text-to-speech, and the resulting message will appear and sound quite similar to a text when you receive it. When an RTT/TTY call ends, the conversation’s text is saved and can be retrieved later for reading or searching.

During the span when RTT is enabled, a user can make a call via RTT/TTY rather than using their voice. Moreover, if your service provider enables it, you can use this method to make calls, where you can type a text into a field and have it read aloud to the person you’re calling. Plus, you can read and respond to their responses on display as they are translated instantly into text.
