Defining Citizen Genders?

Hey all.
Is the some sort of way to make a citizen model edit (in this case, my personal skin), use gender specific sounds, instead of male and female?

That only depends on the npc’s script or whatever. Not the model.

So I would define it in a Lua script then?

Probably. Or whatever the hell else people use to script npc’s.
I know zero about any kinda scripting so I don’t know really.
