I don't think I'm special in this respect, but I didn't find the example clips that were given too hard to discern.
Look for enunciation of certain latters such as P and M, and you should be able to tell the difference. The generated image gives a sense of moving the mouth but not enunciating the words clearly. Almost as if she is gliding over the words. With the real movie, however, you can see the woman completely changing her mouth formation to form the sounds required to pronounce the words.
