Scream detection?

[Bridge]

It could be a solid idea I guess were it not for the fact that the entire system can be circumvented by not screaming. There do exist people who don't react to danger by screaming. Hell, when I play Amnesia I scarcely say anything at all. Then there are inevitable background noises which unless you have amazingly effective background noise filters on your mic are going to cause you to die. It's just not worth the hassle in my opinion.
