"Real-time Text (RTT)" sub-heading:
Real-Time Text (RTT): form of a text conversation in point to point situations or in multipoint conferencing where the text being entered is sent in such a way that the communication is perceived by the user as being continuous
NOTE 1: Users will perceive communication as continuous if the delay between text being created by the sender and received by the recipient is less than 500 ms. However, the actual delay will be dependent on the communication network.
NOTE 2: The creation of text will differ between systems where text is entered on a word-by-word basis (e.g. speech‑to‑text and predictive-text based systems) and systems where each character is separately generated (e.g. typing on a physical keyboard).
