问题     When Apple showed the world Siri, I believe they showed us the next major【C1】______user 【C2】______
    The idea of talking to computers is nothing new. It has, of course, been【C3】______in scifi novels, movies and TV shows for years now.【C4】______software itself has shown shades of voice input【C5】______the next user input for over 10 years. The challenge had always been bringing it to the【C6】______market. This is what Apple plans to do with Siri on the iPhone 4S.
    This technology has been in development for quite a while and is getting【C7】______better.【C8】______bringing it to the mass market, another challenge has been making it useful by【C9】______simple dictation. One of the most【C10】______elements of Siri is not just the ability to do voice-to-text dictation, but its ability to turn natural-language【C11】______into action.
    What I mean by that is that I can use my voice to say, "【C12】______me to feed my goats when I get home." Because Siri is trained to know where my house is and the iPhone 4S has GPS, the【C13】______I drive into my driveway, I get a reminder that tells me to feed the goats. I live on a farm and this is quite【C14】______for me.
    It’s a valuable【C15】______to be able to use voice commands to create calendar items, search the web, get【C16】______information like how many feet are in a mile, search local information, set alarms, 【C17】______the weather, and much more. This can be done【C18】______Siri is tied to some very powerful databases and, through its AI and voice comprehension technology, can【C19】______some amazingly accurate information that has already proven helpful to me and many【C20】______have used this technology.
【C15】
