This is a letter from AEW HR. You are hearing your own voice in your head as a way to illustrate that you are reading this letter to yourself; this is a common TV trope. Your voice is not the voice of the HR representative writing this letter. Do not get confused, you do not work for HR. And if you did, you probably would've been fired by now.
"Todd! Stop singing your dumb scrambled eggs song! If you are wondering who said that, it's this note that you are reading."
