Abstract:
1. A method for processing a teletypewriter (TTY) call on a mobile device for displaying text associated with said TTY call, said method comprising: providing access to at least a first communication line configured to send and receive TTY calls directly without requiring additional equipment; examining an incoming or outgoing TTY transmission associated with said TTY call for one or more cues to detect speaker changes; upon detecting a cue indicative of a speaker change, identifying characters received from a prior correspondent which complete a word initiated prior to detection of said cue; associating a portion of said text with a respective correspondent participating in said TTY call, said correspondent being said mobile device for outgoing TTY transmissions and being an other party for incoming TTY transmissions; and identifying said respective correspondent for said mobile device by modifying said portion so as to cause text associated with different correspondents to be displayed differently wherein such modification includes modification which causes text corresponding to characters received prior to detection of a cue indicative of a speaker change to be displayed on a display screen provided by said mobile device during said TTY call adjacent to any subsequent characters received from the same correspondent which complete a word initiated prior to detection of said cue.
