This is an amazing idea!

You should give pig people that tiberian fiend snorting sound from tiberian sun.

Added some various settings for optional patches, let me know if you encounter any issues :)

I have managed to do some XML patch magic to optionally find all pawn voices like the pig people, and change their voices to the ones added here. I will likely make those optional patches.

I am also slowly figuring out how to replace the baseliner sounds, as they do not rely on genes. I wonder if the genes kinda "override" the sounds provided in the core game, in order to achieve their effect. hmm...

Honestly? I love this idea. voice genes sound like an awesome way to merge worlds

I was thinking about it, but only just got it working. Might do one if I can get an optional patch working that replaces all other voice sounds with the ones used here.

It is super easy to try out tho, just start a new crashlanded colony with pawns that have a custom xenotype that only uses this gene. Make them stab or shoot each other, and you can test out the sounds :p

I have a feeling it will make large fights pretty funny if I can get a patch working.

This mod uses the "unit lost" EVA sound when someone dies, and the actual sounds of infantry dying is used for the "hurt" sounds. The idle talk sounds are some of the "affirmative"-like sounds for infantry.

Any chance of a video with an example? Sounds interesting.
