The iPhone 4S is a touchscreen-based smartphone developed by Apple Inc. It is the fifth generation of the iPhone, succeeding the iPhone 4, and was announced on October 4, 2011. Siri on iPhone 4S is like a person assistant. It lets you use your voice to do things on the iPhone. You can just talk to Siri as you talk to a person. Siri understands what you say, knows what you mean, and even talks back.
Say something like “Tell my wife I’m running late.” “Remind me to call the doctor.”“Any fast food restaurants around here?” Siri does what you say, finds the information you need, then answers you. It’s like you’re having a conversation with your assistant.
Siri not only understands what you say, but it’s also smart enough to know what you mean. So when you ask, “Any fast food restaurants around here?” Siri will reply, “I found a number of restaurants near you.” Then you can say, “Hmm. How about French fries?” Siri remembers that you just asked about restaurants for something to eat, so it will look for KFC restaurants in the neighborhood. And Siri is active, so it will question you until it finds what you’re looking for.
When you want to do something, just ask Siri to help you do it. Siri uses almost all the built-in apps on iPhone 4S. It writes texts and sends email messages. It searches the web for anything you need to know. It plays the songs you want to hear. It gives you directions and shows you around. It makes calls, plans meetings, helps you remember and wakes you up. In fact, ask Siri what it can do — it even speaks for itself.
Siri is easy to use and does so much. You’ll keep finding more and more ways to use it.
