One of the most impressive features of the new iPhone 4S is Siri, Apple's new voice-controlled assistant. For those wondering what you can say to it the Unofficial Apple Weblog (TUAW) has posted a very comprehensive list of options. Here are a few examples and how they work.
When adding events, you can say things like "Set up a meeting at 9", "New appointment with Susan Park Friday at 3", and "Schedule a planning meeting at 8:30 today in the boardroom". If you need to change an event, "Move my 3pm meeting to 4:30" will work. If you just want to hear about existing events, you can say things like "What does the rest of my day look like?" and "When am I meeting with Michael?". The voice interface is designed to be very natural and understand how you would normally talk.
Siri has full access to your address book, so if you want an address, for example, just ask "What is Susan Park's address?" To see a contact on your screen, "Show Jason Russell" is sufficient. You can also specify relationships by saying things like "Michael Manning is my brother."
Waking up tomorrow is as simple as saying "Wake me up tomorrow at 7am." You can also be a little less specific about the exact time and say "Wake me up in 8 hours." If you change your mind, "Delete my 7:30 alarm" will get rid of a particular alarm. Of course you can always just ask for the time or the date as well. If you want to add something to the Reminders app, specifically, then just start off the sentence with the word remind. For example, "Remind me to finish the report by 6" will get the job done.
Siri can compose messages for you. With emails, you can set the recipient and subject in a single sentence by saying, for example, "Email Jennifer about the change in plans" or "Mail Dad about the rent check." Saying "Check email" will, of course, check your email, but you can get a specific message with a command like "Show the email from Lisa yesterday." If you have a message open, a response as simple as "Call him at work" will call the email's sender at their work number if it exists in their contact information. Text messages work similarly. You can send one quickly with a phrase as simple as "Tell Susan I'll be right there." If there are multiple numbers you can send the SMS to, you can be more specific and say "Send a message to Susan on her mobile saying I'll be late." You can also specify the number numerically if you don't have it in your contacts.
Siri can provide you with directions very easily. One of the most common questions you'll want to ask is "How do I get home?" You can also ask for directions to a specific address (e.g. "Show 1 Infinite Loop Cupertino California") or to a location in your contacts (e.g. "Directions to my dad's work"). If you're looking for something non-specific, that's okay too. Just say something like "Find coffee near me", "Find a gas station within walking distance", or "Good Mexican restaurants around here".
Siri can handle your web search requests in a couple of ways. You can just say "search for" and then follow that up with your search terms. Alternatively you can ask it a question for Wolfram Alpha to answer. Things like "What is an 18% tip on $86.74 for four people?", "What was the Best Picture of 1983?", and "What's the price of gasoline in Chicago?" are all within Siri's ability.
Playing music isn't really a new feature for Siri, as you can do it now with the existing Voice Control in iOS 4, but it's good to know it is alive and well. Saying the word play followed by a song or artist name, or even a playlist, will get the music started.
Siri can check information that you'd generally locate in your widget-like apps, such as stocks and weather. To check the weather, just ask whatever you want to know. "What's the weather for tomorrow?" or "Will it rain in Seattle this week?" are both specific enough for Siri to figure out. With stocks, you can ask things as "What is Apple's PE ratio?" and "What did Yahoo close at today?", or just request a simple stock price by saying "What's Apple's stock price?"
And here is a video showing off all those features in action!
Unfortunately for iPhone 4 users Siri is available only for iPhone 4S although developers found out that it can run on iPhone but it is locked.
Anyway, did you like Siri? Has anyone experience on it?
