In the latest version of the Google Search App for iOS and Android, not only can you say your question out loud, but your search app can speak your answer right back to you. And, using Google’s Knowledge Graph, your search app gives you smarter answers loud and clear.

Search without typing
Now you can ask your phone anything, anywhere. Use it in the kitchen, in the garage or anytime your hands might be full. Plus, searching with your voice makes searching words you’re not sure how to spell quicker and easier.

You’ve got questions. Voice search has answers.
When is your flight leaving? How is the weather this weekend? How much is $100 in Euros? How tall is the Eiffel Tower? With voice search, now you can hear your answer loud and clear.

Also Available: Voice Search on your desktop

Voice search also works on your computer. All you need is a built-in or attached microphone. Just click the mic in the search bar and start talking.
