I've installed voice-to-text software -- the one advertised on TV. I had tried it in the past but computer power and the software both left a lot to be desired.
Given my new computer (I had an XP machine that is now obsolete, so got a Windows 7 thing) I thought I'd try it again. It does do a lot better and it is fairly fast.
However, the accuracy rate is still at 95% -- that means one in twenty words is wrong and you have to take the time to correct it. Given that lawyers use a LOT of words, that's a lot of corrections.
I just looked at something I 'dictated' into the computer. Visions of instructions for electronic devices from Asia, written by a non-English-as-first-language person came to mind. I'll have to be careful.
