Siri

Siri is a voice control and dictation software made for the iPhone 4S and later, iPad 3rd Generation and later. Siri allows you too ask it questions in a normal voice and it will "not just hear, but understand the meaning of what your saying."

Talk to Siri as you would to a person. Say something like “Tell my wife I’m running late.” “Remind me to call the vet.” “Any good burger joints 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 iPhone.

Siri not only understands what you say, it’s smart enough to know what you mean. So when you ask “Any good burger joints around here?” Siri will reply “I found a number of burger restaurants near you.” Then you can say “Hmm. How about tacos?” Siri remembers that you just asked about restaurants, so it will look for Mexican restaurants in the neighborhood. And Siri is proactive, so it will question you until it finds what you’re looking for.

Ask Siri to text your dad, remind you to call the dentist, or find directions, and it figures out which apps to use and who you’re talking about. It finds answers for you from the web through sources like Yelp and WolframAlpha. Using Location Services, it looks up where you live, where you work, and where you are. Then it gives you information and the best options based on your current location. From the details in your contacts, it knows your friends, family, boss, and coworkers. So you can tell Siri things like “Text Ryan I’m on my way” or “Remind me to make a dentist appointment when I get to work” or “Call a taxi” and it knows exactly what you mean and what to do.

When there’s something you need to do, just ask Siri to help you do it. Siri uses almost all the built-in apps on iPhone 4S. It writes and sends email messages and texts. 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 places calls, schedules meetings, helps you remember, and wakes you up. In fact, ask Siri what it can do — it even speaks for itself.
