Apple has updated its website and has replaced the picture on its Siri page. The image on the page now shows the fourth-gen iPad next to the Apple iPhone 5s where previously the Apple iPhone 5 was in the picture. Apple says that Siri now "understands what you say, knows what you mean, and even talks back."
Siri will now search in Twitter and Wikipedia, and web search results from Bing. Siri now can answer you as a female or male, in English, French, or German. In addition, Siri has been boning up on sports knowledge and can also make restaurant reservations as well as learn how to pronounce a new name. And in iOS 7, Siri can post to Facebook or Twitter and even open certain apps.
