Everything you need to know about iOS 7 Siri: Apple's personal digital assistant gets a new look, new voices, and new connections to Wikipedia, Twitter, Bing, and settings.
Just like everything else in iOS 7, Siri has been given a new, layered look that blurs but doesn't entirely hide everything beneath it. Siri also has a new voice wave and two new voices, male and female. Siri can also access settings now, as well as Wikipedia, Bing, and Twitter.
