How to make a character say something random instead of a scripted line when examining?

[Craos]

I plan to make a character that I want to say something random instead of a scripted line like most characters. I have seen this before (with Wilton the haunted if you are curious) and I want to know how to do this. If you don't know what I am talking about, basically when examining the character would say let's say a bunch of random letters instead of a unique line for each item, mob ect. They can also say a different bunch of letters instead of the same bunch each time. So instead of saying the same thing for each item, the game would pick a random coded line for examining an item. Any help would be appreciated. If you still don't understand what I mean... well I will explain it further to a confused reply.

You should download the mod in question and look at the code to see how they did it. :]

use an array instead of a single string:
{"ah","ih","uh"} will say randomly one of these three.
