They talk about intonation… A good example is the scene in Three Men and a Baby where he’s reading a wrestling magazine to the baby.
Also, it talks a lot about physical states representing emotional states, and gives (at one point) the example of someone who’s feet sweat when they’re nervous. However, it seems to me that whether someone’s feet sweats or not should not be something that we’re trying to figure out. Really, it’s irrelevant to my model of that person’s internal state. The robots should be autonomous and it seems fairly pointless to be able to determine someone’s emotional state if the only way we can do it is by hooking the person up to complicated sensors. It seems more practical to be able to (or to try to) model emotional states by non-tactile means.
