How can I eliminate phantom spelling errors?

Question

I use Word for several hours every day and I push the limits a little with Dragon speech recognition software, extensive use 
of Word macros, and daily use of Review, Compare, Compare. Perhaps at least once a day I look in the document and see that “phantom” spelling errors have arisen. For example, I’m looking at a page presently in which the letters “andard” in the word “standard”
are underlined with the red wavy line. Similarly the “ic” in the word “quadratic” is underlined with the red wavy line, and the “erived” in the word “derived” is also underlined with the line.
I can make these red wavy lines disappear by simply pressing F7 to check the spelling, which (assuming there are no “real” spelling errors in the document) causes them to disappear and I get the message “The spelling check is complete.”.
The red wavy lines are distracting. Is there a way that I can make them permanently go away (without turning off automatic spell-checking)?
Thanks for your help,

Answer 1

Or, perhaps, you could alert the folks who produce Dragon Naturally Speaking since it seems to be a problem caused by their software? I believe that is Nuance.
BTW, I stopped using DNS a while back because I type faster than it would accept dictation and with fewer errors.
Thank you. That's a useful suggestion. However, I expect that the MS Word developers are very careful about preventing external programs from messing up Word (because Word gets blamed when this happens).  So there should be no way that a bug in
Dragon Naturally Speaking (DNS) could cause phantom spelling errors in Word.  Or if there is a way, then the Word developers should make changes to Word so that this can no longer happen.  (I expect that the interface that Word exposes to other applications
is very carefully designed so that if the external applications do "bad" things, they can't cause Word to misbehave.  (They shouldn't even be able to "hang" Word, although DNS sometimes does that because it appears to be thrashing. 
But the problem goes away if I wait or if I kill DNS.)
Sorry to hear that DNS was too slow and error prone for you.  For me, if I enunciate clearly and speak in longer phrases, and use an approved microphone, a 10-or-15 word sentence is correctly typed as soon as I've finished saying it.  And talking
is much easier than typing, even though I've been touch typing for more than 40 years.
You do need a sufficiently modern CPU to use DNS because it's highly CPU-intensive.  They recommend a modern processor with 2 MB L2 cache.
