With iOS 7, Apple is drastically expanding the capabilities of Siri, its built-in personal assistant for iPhone and iPad owners. The app has been totally redesigned, and users can choose either a female or male voice in their native language — both sounded more natural than what Siri currently produces. Users can also now query Siri for results that include content from Wikipedia and Twitter. When demonstrated on stage, the new Siri pulled in web results from Bing. It's unclear whether Microsoft's search offering will be your only option when using Siri, but Apple is also touting the integration on its official iOS 7 page.

Siri will have integrated Bing web search built in, so when users ask Siri a question either the specific answer or web search links will now be delivered automatically so users can find information and accomplish tasks even faster"
