Siri is a highly intelligent, HAL-like talking software inside the iPhone 4S. It not only understands sentences and phrases and commands but assesses and reports back to you, like a personal assistant. Will it have different voices? I’m not sure I want my personal Siri to sound like some middle-aged lady at the DMV. I’d rather talk to some guy who sounds like Pee Wee Herman. I’m probably going to have to repeat things to Siri, and I may sometimes lose my temper with it. “Yes, asshole…I just said that!”
