Siri (Speech Interpretation and Recognition Interface) (pronounced /ˈsɪri/) is an intelligent personal assistant and knowledge navigator which works as an application for Apple’s iOS. The application uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of web services. Apple claims that the software adapts to the user’s individual preferences over time and personalizes results, and performing tasks such as finding recommendations for nearby restaurants, or getting directions.
Siri was originally introduced as an iOS application available in the App Store by Siri Inc. Siri Inc. was acquired by Apple on April 28, 2010. Siri Inc. had announced that their software would be available for BlackBerry and for Android-powered phones, but all development efforts for non-Apple platforms were cancelled after the acquisition by Apple.
Siri is now an integral part of iOS 5, and available only on the iPhone 4S, launched on October 4, 2011.Despite this, hackers were able to adapt Siri in prior iPhones. On November 8, 2011, Apple publicly announced that it had no plans to support Siri on any of its older devices.
The Siri software is deeply embedded throughout iOS that it is able to interact with a number of native applications, offering an enhanced user experience. One of the main gripes from a consumer point of view is that Siri is only officially made available by Apple for those who purchase an iPhone 4S. At first glance, it would seem that Siri required the more powerful processing power of the A5 processor, but considering Siri has been made available on older generation devices by the jailbreak community and seems to function without issue, that assumption would seem to be negated.
