Siri. Siri is a voice-controlled intelligent personal assistant developed by Apple Inc. and integrated into its operating systems. It uses natural language user interface and voice queries to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. The assistant adapts to users' individual language usage, searches, and preferences, with continued use.

History

The technology originated from a project developed by the SRI International Artificial Intelligence Center and was spun off as an independent company in 2007. The startup, also named Siri Inc., released an app for the iOS App Store in 2010. Apple Inc. acquired Siri Inc. in April 2010, and the assistant was integrated into the iPhone 4S at its launch in October 2011 under then-CEO Steve Jobs. Initially supporting English, French, and German, Siri's language support has expanded significantly over the years. Major updates have been tied to new versions of iOS, with notable advancements like deeper integration with HomeKit and the introduction of Siri Shortcuts in iOS 12.

Features and capabilities

Siri can perform a wide variety of tasks, including setting alarms, sending text messages, making phone calls, and providing weather forecasts. It integrates deeply with Apple Music, Apple Maps, and the Calendar app to play music, provide navigation, and manage schedules. Users can control HomeKit-enabled smart home devices, such as Philips Hue lights or August Smart Lock locks, using voice commands. With Siri Shortcuts, users can create multi-step automations or launch complex tasks with a custom phrase. The assistant also provides sports scores, stock market data, and answers to general knowledge questions by pulling information from sources like Wolfram Alpha and Wikipedia.

Technology and development

Siri operates using a sophisticated combination of speech recognition, natural language processing, and machine learning technologies. User speech is processed locally on the device for basic commands and converted to text, which is then often sent to Apple servers for more complex interpretation. The backend system utilizes a powerful artificial intelligence engine that parses intent and entities from queries. Development is centralized within Apple's Software Engineering departments, with significant contributions from teams specializing in ML and Core ML. Advances in neural networks and on-device processing, particularly with the A-series and M-series chips, have allowed more functions to be performed locally, enhancing speed and privacy.

Reception and impact

Upon its debut, Siri received significant media attention and was praised for its ambitious integration of AI into a consumer product. Reviewers from The Verge and Wired noted its potential despite early limitations in understanding and accuracy. Siri's introduction is widely credited with popularizing voice assistants and catalyzing development of competitors like Google Assistant, Amazon Alexa, and Microsoft Cortana. It has had a substantial cultural impact, frequently being referenced in popular culture and becoming a standard feature expected on smartphones. However, over time, some critics and users have noted that competing assistants sometimes surpass Siri in certain areas of comprehension and web search capability.

Privacy and security

Apple has positioned Siri's privacy approach as a key differentiator, emphasizing on-device processing where possible to minimize data sent to its servers. Audio recordings of most Siri interactions were not retained by default, a policy adjusted in recent years to allow optional, anonymized review for improving the service, with explicit user consent. All data transmitted to Apple servers is encrypted and associated with a random, rotating identifier rather than an Apple ID or IP address. The company has faced scrutiny, including from The Guardian, regarding contractor review of audio snippets, leading to policy changes. Siri requests related to Health data, Messages, and Mail are processed entirely on the device.
