Adding a new crew voice line - Possible?

[Tabris]

I'm afraid I don't understand. I've scrutinized this mod quite closely, both when I first downloaded it last year and against just now, and I don't see how it's relevant here. It seems to modify existing sounds - my objective here is to add new voice lines or sounds, if that's even possible. Am I just being dense and not seeing it? Thanks in any case.
