Hello! Unfortunately I can't remember the process, but R41N's info here helped:

A template project file is above.
So it's all based on file names. In the project, add as many actors as you want via the
VoiceActedRadioChatterMod.voiceActors.Add("FemaleYOURNAMEHERE");
They have to start with Male or Female to be read by the game.
Build that as a .dll and place it in the Assemblies folder of your mod.
Then go into Defs/SoundDefs/ and make sure there is an .xml file named UnitResponseFemaleYOURNAMEHERE.
Use the template or copy another make sure that they all point to a folder
Sounds/UnitResponse/FemaleYOURNAMEHERE
The folder needs to be filled with the right file names pointed to in the .xml files.

I think it was mostly trial and error. I think if you search visual studio compile as .dll it'll give some quick tips. Unfortunately I'm slammed--if I can get time next month I'll try and get back to you

Hello, I saw you somewhat recently went through this. I was curious if you could help me make a .dll so i could follow the process? Thanks!

Right on! If you look at the comment thread of the link in the description, you'll see that R41N shared the files he used to add voices.

Nice since i sorta want to do one but with idk conker live and reloaded voices for tediz or SHC squirrels one day

This adds a new voice line.

Question does it add an new voice liine or does it replace an voice line?
