Siri helps you to use your voice to write messages, schedule meetings, search the web, and so much more. Ask Siri to do things just by talking, and she will totally understand what you mean. Siri is so easy to use and does so much; you’ll keep finding more and more ways to use this great service from Apple. All you have to do is to say what you want to do and instead of typing, tap the microphone icon on the keyboard, then say what you want to say and when you finish just tap Done, and your words are converted automatically to text.
Inpite of the fact that Apple still uses Google as the default search engine for web browser, Safari, still things have changed a little with iOS7 for Siri. Siri now uses Bing as its default search engine instead of Google, which might be annoying to lots of people, but there is always a way to edit that and get back to Google. Maybe you won’t get to change that in your settings on iPhone, however you can ask Siri to search Google, tricky right!
Like you normally hold down the Home button in order to start talking to Siri, instead this time you will just ask her to search Google for whatever you want to search, so if you want to search “Top 10 Horror Movies” you should say “Google the top 10 horror movies” simple as that! This way Siri will get you the results from Google and not Bing, all you have to do is to say “Google”.
