If there is a case where you would like to change the way a word is read in Natural Reader you can make adjustments using the Pronunciation Editor. The example on the Natural Reader website is M.D. If you were reading a book where M.D. referred to Mike Dion and you wanted to hear his full name read rather than M.D. you would simply go to the pronunciation guide and replace the source word with the word you want to hear. The Pronunciation Editor is under Tools.
