Chat Robot

Hi, in a game I am making, I have it so that when a user types a message, and clicks Send, their message appears in the upper part of the screen. Is there any way that I can make a chat bot that will talk back to you using voice (if i recorded my voice) or just by text? For a VERY detailed example, send an AOL instant message to ZolaOnAOL, its AOls new chat bot…I would like something similar to it, but A LOT LESS DETAILED!

Thx A lot. :thumb:
