SIRI (Speech Interpretation and Recognition Interface) 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.

What is Siri ?

“Siri on iPhone 4S lets you use your voice to send messages, schedule meetings, place phone calls, and more. Ask Siri to do things just by talking the way you talk. 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.”

– As said on

Siri was launched first as an application available on Apple’s App Store in the US. It integrated with services such as OpenTable, Google Maps, Movie Tickets 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 15, 2011.

A Brief History of SIRI

Siri is not Apple’s first venture into voice-activated controls and speech-recognition, although the program makes a few big leaps over the capabilities of VoiceOver, the technology used in Mac computers since OS X 10.4, as well as iPhones since iPhone 3GS. One of the big differences is that VoiceOver was touted as an accessibility feature, meaning it was mostly used by the visually impaired and people who can’t easily operate iPhones (Parkinson’s disease patients, for example), while Siri is meant for the mass market.

Apple did not develop this technology in house. Rather, Apple acquired Siri Inc. in 2010, a company that had developed an iPhone app called Siri Personal Assistant. Sometime after Apple took over the company, the app was pulled from the App Store.

Languages, Accents, and Dialects

The software is technically in beta, so while it’s functional, it does have some limitations. The biggest limitation right now is language support. Currently, you can only use Siri to its full potential when you use American English and you’re physically in the United States. Siri does have options for U.K. English, Australian English, French (France), and German, but if you use the program in any of those language, you can’t search for businesses or locations on a map.

One of the striking features of Siri is that it will improve the more people use it. Siri will be collecting data from users, like their regional accents and dialects and common phrases that people use, and analyzing that information to improve. Additionally, the more you specifically use it, the better it understands your particular accent and characteristics of your speech.
