Real-Time Text: An IP-Based Solution for Accessible Communications
[Commentary] The Federal Communications Commission recently adopted a Notice of Proposed Rulemaking (NPRM) regarding a proposal to use real-time text as a replacement technology for TTY – teletypewriter technology. Many people who are deaf or hard of hearing have relied on TTYs to communicate by text over phone lines for more than 50 years. As described in the NPRM, however, what once was a life-changing technology for accessible communications is now limited and less reliable in today’s Internet-based environment.
Not surprisingly, TTY use has been declining steadily as the transition to IP networks accelerates and reliance on services that new networks enable grows. Given the explosive use of text messaging by so many in today’s society, one might ask: “Well, why not just use mobile text messaging services instead of TTYs?” The short answer is that some choose to do so. The reason is that text message services don’t allow users to send messages in real time, with each letter of the message appearing for the recipient as it is being typed - allowing for overlapping, conversational communications. As a consequence, without real-time text there would be no means for people who are deaf or hard of hearing to send text over distances in real time over IP networks – akin to the real-time communication that voice users will have over these networks. Fortunately, the record described in the NPRM suggests that a solution – “real-time text” (RTT) – may be within reach, and can be brought to market and provide persons with disabilities an IP-based option for more conversational text messaging.
