Wondering if anyone can give me some info or suggest where to look.

I have an HSC student who is having carpel tunnel, RSI etc hand issues. It is making typiing very painful or sometimes near impossible.

I am looking for a voice activated typing program so, she can talk it and it will type into the computer.

 She has one she's tried and it cant get it right---it gets normal words wrong to like "eruption" and especially odd names like ancient places and authors names etc----even if she types it in once to "teach" it

any suggestions for something REALLY good.

TIA
