Google has released a new version of the Search app for iOS and it brings with it a greatly improved voice search experience that you may have experienced on Android devices running Jelly Bean.
The new Google Search app for iOS features a prominently placed voice search button below the search bar and one tap on it lets you speak your query to the device. Your words appear on the screen as soon as you speak them and then the app searches for the answer. For questions with short answers you also get a voice response, just like on Android.
The voice search functionality is available in many languages but if you need the app to read out the response you’ll need to set it to English (US) from the settings.
