Play my voice at normal human speeds.

This is a super minor patch to fix a bug I added (while trying to fix another bug, which it didn't even fix) that made my voice in the tutorial (and all other sounds sometimes) play at like 10x speed. Which, while entertaining, is not great for a tutorial first impression.

Bummer the 🐿 emoji is so tiny and black and white on my preview.
