The voice was slapped together very quickly, but I kinda liked the gravely and imperfect sound I got out of it. I prerendered all the voice lines, but there's actually a godot addon that implements SAM that I might be able to leverage to greater effect if I decide to work more on this project, though SAM just sounds pretty rough in general. I must admit I'm not very knowledgeable with sound, so I'll probably have to do some research to get it sounding tighter. Thanks for the feedback!
