Have you thought about just how Quantic Dream pulled off that "Kara" tech demo on the PS3? If your answer, like ours, was that they actually built a female android and taught it how to speak all those languages and sing, then you're wrong. They didn't do that at all. Female androids don't exist in real life. Sigh.
No, instead they hired an actress named Valorie Curry (actually three different women -- Curry for acting, one for the German and French, and another to sing) to come in and do motion capture for the part, and refined and developed her performance over a series of about eight months before finally capturing it for the tech demo.
You can see the whole process in the video above, and watch the original tech demo below. Yeah, we guess it's cool and all that they put so much care and work into such a quality video -- but not as cool as a real female android. Sigh again.
