Problem is, it's hard for me to be so organized in my thinking. But if the software mistakes one of my words for something else, I need only call up the correction window that appears off to the side of my document to pick an alternative. Once I choose it, the software automatically replaces the mistaken word. If it does not provide me with the correct alternative, I break down and just spell the word I want according to the rules of voice recognition spelling. I often do that just because I lose my patience trying to get the machine to recognize what I have said.
Dictate mode is the usual method people use.
However, it is often necessary to access command mode to make changes, say, to capitalize a word or spell it. To access command mode, one must first use a cue word. Afterward, the software automatically switches back to dictate mode. Writing is different when you dictate your thoughts instead of typing them out. You must know what you want to say before you open your mouth and tell somebody else to put it on paper.
