Siri. Your wish is its command.

Siri on iPhone 4S lets you use your voice to send messages, schedule meetings, make phone calls and more. Ask Siri to do things just by talking the way you talk. Siri understands what you say, knows what you mean and even talks back. Siri is so easy to use and does so much, you’ll keep finding more and more ways to use it.

It understands what you say.

Talk to Siri as you would to a person. Say something like, “Tell my wife I’m running late” or “Remind me to call the vet” or “Do I need an umbrella?” and Siri answers you. It does what you say and finds the information you need. And then it hits you. You’re actually having a conversation with your iPhone.

It knows what you mean.

Siri not only understands what you say, it’s smart enough to know what you mean. So when you say, “Meet Andrew for coffee at 4 o'clock today," Siri will reply, “All right, the meeting with Andrew is on your calendar for today.” Then you can say, “Remind me to call him as soon as I get to the office." Siri remembers that you were just talking about Andrew, so it can set the right reminder. And Siri is proactive, so it will question you until it finds what you’re looking for.

It helps you do the things you do every day.

Ask Siri to text your dad, remind you to call the dentist or send an email, and it works out which apps to use and who you’re talking about. From the details in your contacts, it knows your friends, family, boss and co-workers. 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.

It has so much to tell you.

When there’s something you need to do, just ask Siri to help you do it. It uses almost all the built-in apps on iPhone 4S to find the information you need. Siri writes and sends email messages and texts. It searches the web for anything and everything you need to know. It plays the songs you want to hear. It makes calls. It schedules meetings. It helps you remember. And it wakes you up. Siri tells you almost everything. And it even speaks for itself.

iPhone 4S takes dictation.

Here’s another amazing way to get things done: just use your voice. Instead of typing, tap the microphone icon on the keyboard. Then say what you want to say and iPhone listens. Tap Done, and iPhone converts your words into text. Use dictation to write messages, take notes, search the web and more. Dictation also works with third-party apps, so you can update your Facebook status, tweet, or write and send Instagrams.

Siri is available in Beta only on iPhone 4S and requires Internet access. Siri may not be available in all languages or in all areas, and features may vary by area. Mobile data charges may apply.
