“Joe” and “Jill” have two very different mouth movements.
They absolutely do, if you’re saying the names very slowly and distinctly. You can easily speak with the normal flow of words and the two can sound very much the same in a sentence. Honestly, say them to yourself, quickly, as if you’re speaking normally. Say Jill Biden three times quickly, then Joe Biden. I’m not defending Joe Biden....I’m just saying that this is a little weak.
