Lots of iPhone fanatics had a big disappointment when Apple didn’t release the iPhone 5. But instead, Apple released a more advance version of iPhone 4, the iPhone 4S. To eased the disappointment, Apple equipped the iPhone 4S with lots of amazing features and one of them is the “Siri“.
Siri is an AI equipped in to the iPhone 4S. Siri on iPhone 4S lets you use your voice to send messages, schedule meetings, place phone calls, and more. You can Ask Siri to do lots of things just by talking the way you talk to others. 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.
So what does Siri can realy do? As it was first introduce, Apple claim that Siri can understand what you mean and just how you feel. Besides Siri’s voice recognition, it seems to me that Siri consists of three layers: a speech-to-text analyzer, a grammar analyzer, and a set of service providers.
A speech-to-text analyzer is a piece of software that takes audio and turns it into text. Simple as that. Except it’s not so simple—systems like Dragon Recognition Software have been refining this process for years. It’s really hard to get right, and I’ve never seen an analyzer that didn’t jumble a significant portion of what you say.
Some queston that Siri can Answer:
- Ask for a reminder.
- Ask to send a text.
- Ask about the weather.
- Ask for information (from Yelp, Wolfram|Alpha, or Wikipedia).
- Ask to set a meeting.
- Ask to send an email.
- Ask for a number.
- Ask to set an alarm.
- Ask for directions.
- Ask about stocks.
- Ask to set the timer.
- Ask Siri about Siri.
Siri, however, has a much easier job than Dragon or your Mac’s Speech Recognition system. And that, again, is because its job is limited and focused. It doesn’t have to understand just anything you might say. It only has to understand words and sentences that pertain to appointments, contacts, messages, and maps. This makes it easier for Siri to pick out what you’re saying, because there are only so many things that you’re allowed to talk about.
Another advantage is physical. A phone has a much better chance of hearing your voice up-close than a computer does. Phone microphone technology already incorporates a degree of noise cancellation. So your phone is more likely to be able to hear you clearly, even in the midst of noise, than your computer is.
