Using spoken content/start speech with tracked changes in Pages

I have recently moved from Word to Pages and have come up against a brick wall when trying to use either of the text-to-speech options. I work as a copy-editor, and like to get my Mac to do a final read-through of a document I have edited before I finalise it. For this, I use the "final" option in tracked changes so that none of my changes are showing but, regardless of that, all the hidden changes are being read out, which defeats the object! Can anyone suggest a way round this? Thank you
