What is Siri? — from Apple.com

Siri is the intelligent personal assistant that helps you get things done just by asking. It allows you to use your voice to send messages, schedule meetings, place phone calls, and more. But Siri isn’t like traditional voice recognition software that requires you to remember keywords and speak specific commands. Siri understands your natural speech, and it asks you questions if it needs more information to complete a task.

Siri uses the processing power of the dual-core A5 chip in iPhone 4S, and it uses 3G and Wi-Fi networks to communicate rapidly with Apple’s data centers. So it can quickly understand what you say and what you’re asking for, then quickly return a response.

Siri is currently in beta and we’ll continue to improve it over time.

Voice Control Will Disrupt Living Room Electronics — from techpinions.com by Patrick Moorhead
Excerpt:
In what seems to be a routine in high-tech journalism and social media now is to speculate on what Apple will do next. The latest and greatest rumor is that Apple will develop an HDTV set. I wrote back in September that Apple should build a TV given the lousy experience and Apple’s ability to fix big user challenges. What hasn’t been talked about a lot is why voice command and control makes so much sense in home electronics and why it will dominate the living room. Its all about the content.
