SIRI

Siri (Speech Interpretation and Recognition Interface) / siri/ is a part of Apple Inc .'s iOS, watchOS, and tvOS operating systems. Siri is a computer program that works as an intelligent personal assistant and knowledge navigator. The feature uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to set of web services. The software, both in its original version and as an iOS feature, adapts to the user's individual language usage and individual searches (preferences) with continuing use, and returns results that are individualized.Siri was originally introduced as an iOS application available in the App Store by Siri Inc., which was acquired by Apple on April 28, 2010. Siri, Inc.
had announced that their software would be available for BlackBerry and for phones running Android, but all development efforts for non-Apple platforms were cancelled after the acquisition by Apple.
Siri has been an integral part of iOS since iOS 5[3] and was introduced as a feature of the iPhone 4S on October 14, 2011. Dictation powered by Siri was added to the third generation iPad with the release of iOS 5.1.1 in May 2012; full Siri support was added with iOS 6. The 5th generation iPod touch, released in October 2012, also gained Siri support. Siri has been included on all mobile Apple hardware manufactured during or after October 2012.
Siri is also integrated into Apple Watch's watchOS, where the feature can be activated by holding down the Digital Crown or by saying "Hey, Siri." Siri is additionally integrated into Apple TV's tvOS, where the feature can be activated using a button on the included Siri Remote.
Since 2014 Siri has been available in some cars via CarPlay, a system that enables a the vehicle audio system to be a display and controller for an iPhone. It is available on all iPhones from iPhone 5 with at least iOS 7.1.
iPhone Application
Siri was first launched as an application available on Apple's App Store in the United States by Siri, Inc. It integrated with services such as OpenTable, Google Maps,MovieTickets and TaxiMagic. Using voice recognition technology from Nuance and their service partners, users could make reservations at specific restaurants, buy movie tickets or get a cab by dictating instructions in natural language to Siri. Siri was acquired by Apple on April 28, 2010, and the original application ceased to function on October 14, 2011.

A key feature both of the research and development behind the original Siri, Inc. application, and behind its function as an iOS application, is its artificial intelligence programming aimed to allow it to adapt to the user's individual language usage and individual searches (preferences) with continuing use, with return of results that are therefore individualized.
iOS Integration
On October 4, 2011, Apple introduced the iPhone 4S with their implementation of a beta version of Siri. The new version of Siri is integrated into iOS, and offers conversational interaction with many applications, including reminders, weather, stocks, messaging, email, calendar, contacts, notes, music, clocks, web browser, Wolfram Alpha, and Apple Maps. Currently, Siri supports English (United States, Canada, Australia, United Kingdom, Singapore), French (France, Switzerland), German (Germany, Switzerland), Japanese, Italian (Italy, Switzerland), Spanish (Mexico, Spain, United States), Mandarin (China, Taiwan), Korean, and Cantonese. On launch, Siri had limited functionality outside the United States and Canada. However, Apple, with the release of iOS 6, added the missing functionality to other countries. Siri also replaces 'Voice Control' on previous versions of iOS, which could only perform basic tasks such as play music, make calls and open apps.
In October 2011, independent developers stated that they had ported Siri into the other iOS devices. However, some news sites suggest that the videos posted by the developers as "proof" only show the user interface of the Siri software, and not the voice commands, implying that developers have not been able to port the application with full functionality. However, new reports from January 2012 suggest that independent developers have succeeded in porting Siri to earlieriPhone models, the iPod Touch, and iPad. i4Siri.com, a United States-based team, have demonstrated Siri working as intended on the iPhone 4, iPod Touch, and iPad, communicating without the Apple servers.
In later January 2012, independent developers successfully created and distributed a legal port of Siri to older devices

via Cydia. The port, however, requires authorization keys from another iPhone 4S, which can be exploited in the form of a proxy server, or by transferring the Siri authorization file from an iPhone 4S. Due to this requirement, developers have bypassed Apple's Siri server completely by creating their own backend using APIs from services such as Google and Wolfram Alpha.
In June 11, 2012, at Apple's WWDC conference, Apple announced that Siri will be available on the iPad (third generation) beginning in late 2012 with the release of iOS 6. Also on June 11, 2012, at Apple's WWDC conference, Apple announced updates for Siri coming in iOS 6 (which launched in fall 2012.) These new features include: opening apps, telling sports scores and other sports related information, checking movie times, finding restaurants and also ordering reservations. Siri can also tell the height of sports players in iOS 6. It also brought some previously US only features, such as Google Maps and Yelp integration.
On September 12, 2012, Apple announced that Siri will also be on the iPhone 5 and the iPod Touch (fifth generation).
On June 13, 2013, Apple announced that Siri would have a gender option, meaning that one can choose if Siri will sound like a male or a female, with the release of iOS 7.
During its September 2015 event, Apple announced that Siri will respond to "Hey Siri" voice activation on an iPhone 6S and an iPhone 6 when the device is not being charged. Siri was also introduced for the new Apple TV platform.
Currently, Siri is included on the iPhone 4S, iPhone 5, iPhone 5C, iPhone 5S, iPhone 6, iPhone 6 Plus, iPhone 6s, 5th generation iPod Touch, 6th generation iPod Touch, 3rd generation iPad, 4th generation iPad, iPad Air, iPad Air 2, all iPad Minis, iPad Pro, Apple Watch, and Apple TV.
