Real-Time Text

Giving a new “voice” to the hearing and speech impaired community

For decades, people with a range of hearing and speech impairments had depended on teletypewriter devices (TTY) to communicate by text over phone lines. Then came the smartphone revolution and the freedom of mobile text messaging, facilitated by user-friendly features like touchscreens and keyboards. Bulky TTY terminals were no longer required. Now, with the development of Real-time Text (RTT), an even more authentic conversational experience is available on select smartphones at UScellular®.

RTT has real advantages over TTY and traditional texting

With Real-Time Text, every character is transmitted and received as it is typed, so thoughts can be communicated by the sender and recipient with the immediacy and flow of an actual voice conversation. There is no longer a need to use the “send” button. While these are particularly important benefits for hearing and speech impaired users, anyone can enjoy the speed and interactive advantages that RTT offers over traditional texting.

RTT also supports a broader range of characters than TTY devices. With access to symbols like emojis and multiple languages built into smartphones, messages can be understood faster without the need for lengthy explanations. This is especially critical in an emergency, when every second can count. State and local 9-1-1 emergency call centers are in the process of upgrading to RTT technology, while continuing to support TTY communications.
