I'm looking for a software that could be installed to a laptop, where the listener types what is being said at a conference, and then this shows up live word by word as it is being typed to portable Android devices for deaf users. It has to be cross-platform - Windows and Android so far.
I don't know what to look for, LAN messengers are no good as this requires having to press enter to send, thus it would start to lag behind and no corrections to words can be made.
It has to be LAN only, no internet access. A wireless router can be set up so that the android tablets and the Windows laptop can connect to it.
A web-based solution could also work if anybody knows of any, this should make it easier as browsers on any platform could connect to the laptop's web server to read the incoming text.
