Individual words are easy.  You create an ASCII file called ve.dic.  This
will load with your synthesizer driver.

On the first line you place the word that you are interested in.  On the
following line, you misspell the word to sound like what you want it to be
.  You can alternate words like that until you run out of reserved memory.
The first line is always the correct spelling, followed by another line
with the moisspelled but correctlly pronounced word.
