local; no need for internet- but if I could transmit the text to the LED screen wirelessly that would be better. LED is better for night viewing, so I think LED is better but if LCD is tough and well viewed in dim light that would work as well.

The second part is the speech to text. If I could have say, 10 phrases which are already "printed out" (on the smart device) be able to put on the remote LED display with my device then the second part is to be able to make infinite choices by the speech to text.
