how come in the show were Lizzie wheres that ugly sweater they make her voice go fast? what did she say?

she was just saying what we had already seen in the episode. because this was all she was saying they speeded up her vioce so that veiwers would not have to hear it all again and it not would not take up excess amount of time. hope this helps. i'm pretty sure this is right if i am wrong sorry, but this is what i had always figured!!
