In light of the American #MeToo movement, I wanted to publish this mod that I created that essentially removes almost all of the female settler screams (namely deaths and grunts if we're going to get all technical) from Age of Empires III. It should work on all versions of the game.
When you install the .zip file and extract it, you will see the new .wav files and a ReadMe file with detailed instructions. Essentially, as long as you can locate the <Sounds> folder in your game files, it is crazy simple to apply. You are basically copying and pasting files into a folder. Let me know if you have any questions!
