Intelligent software assistant with Siri
It is a personal assistant application for iOS.
The application uses natural language processing to answer questions, make recommendations, and perform actions by delegating requests to an expanding set of web services.
It uses intelligent techniques and behavior studies to impress the users that a computer could be so "smart". The purpose of developing intelligent software assistant is to create an incredible experience that will help people be more efficient in their lives, in solving problems and the tasks.
In future:-
Siri may adapt to the user's individual preferences over time and personalizes results, as well as accomplishing tasks such as making dinner reservations and reserving a cab.
Siri is very big step in Voice command and Apple has taken really ambitious step, So far everyone is happy about how humorous to query Siri is, really impressive.
Some of the things I noticed, While my screen is locked and I asked Siri "Did I get any emails from Bill Gates" Siri said "for that you need to unlock your phone" that is cool security and smart answer.
While Siri answers weather and non personal questions even if screen is locked it wont answer questions related to my personal data like emails, notes.
Another observation and tell me if I am missing anything.
While network access is disable Siri does not work, so what does it look on internet ?
Even if I ask question related to my inbox etc. it wont work?
Why it has to go to internet if inbox is local?
Is it true that My indexed data is on server so that Siri can query fast?
Who insures that Indexed data is secure and it is in regulated infrastructure?
What if that indexed file gets in bad hands or used to answer someone else questions and not mine ?
With this Apple is definitely getting into indexing business, This could be indexing of users personal data.
I am sure with that idexed data they will be 10 times accurate in showing correct results.
In future anyone may use those indexed files to get answer of anyone's questions…

Default setting would allow it to be used to send emails and texts even while the screen is locked with a passcode.
Try this :-
long press the hold button on Siri and ask any address?
Make sure you protect your phone...
