What is "Announcer Voice?" This is a lame attempt to take up space in your essay by adding fluff sentences such as:
"I am now going to tell you about this novel."
"Oh look, you are now in my conclusion, you lucky soul."
"I have now told you all about this topic."
NO, friends, NO. We will NOT use the announcer voice. Don't Forrest Gump your essay. If Nike can Just Do It, so can you. Say what you want to say - don't announce that you're about to say something, followed by another announcement that you just said something. If you don't have enough content to write an adequate essay, GO FIND MORE. Nobody is fooled by filler material any more than when you increase your font size to 20 to make your essay look longer.
