Voice recognition problem

I don't know if this is an option because I don't know the extent of your handicap, but if possible, don't place the computer in sleep or hibernate mode. The reason is that some devices, and sometimes programs, do not operate properly when they resume, as you have encountered. I have come across computers that if allowed to sleep or hibernate, the USB ports would not operate until after a restart. I know this probably the answer you are looking for but if at all possible, I recommend either leaving the computer on normally or shutting it down. I hope this helps.
