Hi, there! I've made a mod that overwrites audio files. Alas, the override/ folder cannot be used for this and the original files themselves have to be overwritten. The files you're looking for will be in PillarsOfEternityII_Data\StreamingAssets\Audio\Windows\Voices\English(US) Here's how I modified the files: Step 0) Back up the files Step 1) Download Divinity Sound Converter
Step 2) Place the .wem files in the converter's root folder, run the divinity_converter.exe. The .ogg's files will end up in NUMBERED or NON-NUMBERED
Step 3) Modify the files as you see fit, using Audacity or something.
Step 4) Download Audiokinetic Wwise
Step 5) Create a new project in Wwise
Step 6) In "Project Explorer" in the top-left, go to the ShareSets tab, then expand the Conversion Settings -> Default Work Unit folders
Step 7) Double-click Default Conversion Settings, change Format to Vorbis and set Quality to 6. Then, you may close that window
Step Go back to Audio in Project Explorer and click Actor-Mixer Hierarchy -> Default Work Unit
Step 9) On the bar on the top-left, Click Project... -> Import Audio Files. Change the "Audio file destination" folder to an appropriate folder for the converted files to be placed, then click "Add Files". Highlight which files you want to convert Step 10) Click Project... -> Convert All Audio Files. Tick everything if it isn't already, then hit OK
Step 11) Your files will end up in the ProjectName/.cache folder. You may have to go through a few folders before you find them. Step 12) Now, here's the annoying bit. By default, Wwise appends strings on the end of the file names for some reason. I've found a .bat script to rename them en masse to the correct names. Using the code I've pasted below, open Notepad, paste the code in, and save it as "rename.bat". Then move it to the folder with all the .wem files you just made and run it.
Step 13) Copy and paste all of your modified files over to the game's files and it will overwrite them all rename.bat
setlocal enabledelayedexpansion
for %%i in (*.wem) do (
set ffName="%%i"
ren "!ffName!" "!ffName:~0,-14!.wem"
)
Hope this helps!
