OK it turns out I’m actually just dumb 😣. I listened to it a bunch of times trying to pin it down and finally identified that it was audio fuzz.

“only one I found,” “long-lasting,” “spearmint, cooling peppermint” “cinnamon is called” those were all around the parts where I thought I was hearing something, and then the last section was clear, and when I turned the volume up, those parts all have a sort of “blown out mic” sound with a low frequency, and I heard that sound as part of your voice.
