Google is on track to renew its Search app on iOS and improve the voice search by adding Google Now-flavored recognition. Yet there is no further specification available but it will be coming soon.
It would be very easy to interpret natural speech through Google Voice Search and can even give you spoken replies at times. With the help of this app users can check weather, cinema schedules and more. It will give a direct competition to Siri on iOS but it won’t be able to launch apps or work with the built-in navigation in iOS 6.
Google is coming up with its Knowledge Graph outside of the US to the entire English-speaking world. Knowledge Graph includes more than 500 million people, places and things with more than 3.5 billion connections between them. It has the ability to provide users with location-specific answers to online queries, for instance if you search for “chiefs” in Australia you’ll get the Aussie rugby team complete with scores, players and history.
