Compiling to MOBI, text read out loud by default

Hi there,
When my mobi file opens in kindle, it is reading it aloud by default. Every other book in my library that I open says nothing, but when I open mine, it’s being read outloud by default. I’m assuming there is a setting in Scrivener that I need to change,
Any advice would be appreciated. :smiley:
Thanks!
Peyton
