Hello, Kirk, I tried your capitalisation adjustment suggestion and I still got the very low pitch change upon moving to a capitalised letter. Again, the pitch cannot be controlled with the insert 3 and 4 keys either--it is as though it is locked to its setting. Whenever the pitch drops, I am forced to use the Braille Lite's speech settings to set it back. Anyone wish to take up the change of fixing this bug? I am not much of a C coder, so you wouldn't want me touching your code. :P Robby
