I must admit, that I was one of close-voters (but not the initiating one) and I voted to leave it closed, so I am one of the bad guys ;-)
The question itself is nice and very intriguing to have some software that recognizes speech and transforms it into LaTeX commands, as the OP requested.
However it's a question that is very peripherally connected to LaTeX/TeX itself since the OP misses features in software basically nobody can contribute to, contrary to the fact that basically one of the LaTeX core developpers and package authors contribute to LaTeX/TeX or provide support to LaTeX code generators (which does not seem to be case for Dragon NaturallySpeaking software), so I hold the question, unfortunately enough, for off-topic, although the background is quite nice and justified with the accessibility tag as Barbara Beeton suggested in her comment.
Franck, I hope you're not too disappointed about this and stay at our community nevertheless.
