Before and after the release of the iPhone 4S, tech reviewers profiled Siri, its voice-recognition software that allows users to speak in their natural voices to schedule meetings, send messages, locate resources, place phone calls, and more.
Emerging from CALO, the artificially intelligent personal assistant project that was funded by the artificial intelligence software company SRI International and DARPA, according to MIT's Technology Review, the Siri Apple iOS application (that was acquired by Apple Inc. in April 2010, according to Scobleizer ) uses natural language processing to answer, recommend and delegate in response to a user's questions and requests, even when spoken to informally, imitating a human personal assistant.
Siri adapts to personal preferences with ongoing use, according to marketing claims, and interacts with other applications to perform many complex tasks, presenting a major advance over other voice-recognition software, according to technology reviewers from Wired, eWeek.com and MercuryNews.com.
The reviewers listed diverse capabilities: Siri can give directions, send messages, schedule appointments, recommend nearby restaurants by cuisine type, advise about weather conditions, remind about events, wake you up, remember contacts, friends and favorites -- even philosophize, the CNN reviewer enthused facetiously.
Though Siri does not know how to tweet, a workaround makes this possible, too, Mashable reported.
The voice-recognition technology that powers the female-voiced Siri, originally a standalone application (that Apple pulled recently), was developed by Nuance Communications, though Apple and Nuance have kept this relationship quiet, perhaps so Apple can switch to another company's product or develop its own voice-recognition engine in the future, according to TechCrunch.
As Digital Journal reported recently, the iPhone 4S boasts an improved camera and faster processor, and is sold by Sprint Nextel Corporation and Verizon Wireless (and by Apple, of course), and costs about $200 with a two-year contract.
