Actually now that you've mentioned that, let's add exclamations to the original question. To wit, in Hebrew are questions, exclamations, and statements actually vocalized differently (as they most certainly are in English) or is everything contextual?

Could "Ma tovu..." be turned into a question simply by a change in speech inflection?
