I could see using this for character speech in game. I.E. your character responses when you give them orders. However, as it's not an rpg - we wouldn't really need to be using this to converse with one another.. and that kind of reduces its potential usefulness significantly. It would be an interesting little feature, but i'm not sure if it is worth the time invested if they are not already implementing it into the character dialogs.
