And for anyone using a Screen Reader it's a right pain in the arse.
You have to disable the SR so it doesn't echo the screen while the dictation software is running, otherwise you hear yourself say something, the SR echo it back as it appears on the screen, & then the dictation program regurgitate the echo as it thinks the SR voice was your own.
Disable the SR, dictate your stuff, disable the dictation software, enable the SR, have the SR read back the dictation so you can make the corrections, then repeat the entire cycle for the next bunch of dictation.
Or we could just use a keyboard & get ~10x as much work done in the same amount of time with ~1/10th the migraine.
All of which ignores the fact that, since a blind person can't see to aim a mouse (or any other pointing device), we often have no reason to even own a mouse in the first place. Maybe for those times when we have to "borrow someone's eyes" so they can try to figure out WTF is happening on a monitor we also have no use for, but in such cases we won't be using the dictation function either.
