Apple unveiled its new iPhone yesterday, the iPhone 4S , which has an improved processor, camera and a larger screen. However, what really stole the show was Siri which is a new voice-control system that enables you to control your phone with your voice.

 

The video above outlines a number of things that you can do with Siri. You can easily respond to a text message using voice commands , as well as set reminders in your calender.

 

Siri can also work out answers to questions you ask it such as "What is the weather like today?" , "How many pounds are in 100 dollars" and "What is the best restaurant on 5th Avenue?". Siri will find the answer to these questions and report that back to you in double-quick time.

 

In order to use Siri you just hold down your home-screen button and ask your question or give your order. We can't help thinking we'll feel "goofy" when talking to our mobile phone, but once we get used to that initial shock we're sure we'll find Siri brilliant.
