Apple will bring a full featured version of its intelligent voice recognition service, Siri, to the iPad in the next version of the company’s mobile operating system according to a new report from 9to5mac.com, AFP reports.

“According to trusted sources, one of the tentpole iOS 6 features is Siri support on the iPad. Not just the Voice Dictation brought to the iPad with the third-generation models and iOS 5.1, but the complete Siri voice assistant,” says the blog.

The information leaked ahead of Apple's Worldwide Developers Conference next week also suggested that the tech giant would release new MacBooks and 3D maps.

According to a 9 to 5 Mac report, Siri will make the move from iPhone to iPad, where it will be able to execute all commands except those relating to making calls.

Siri for iPad is expected to take up a small portion of the screen, overlapping whatever app is open at the time rather than the full screen version on the iPhone.

According to Stuff.co.nz, while the iPhone 5 with a larger screen and thinner body is not expected to launch until October, Apple will reportedly announce a new operating system for iPhone and iPad at the San Francisco event next week.

The software, iOS 6, is expected to include Facebook integration, in a similar way that Twitter is currently integrated into the iOS 5 operating system.

9 to 5 Mac report also said Apple is also expected to replace Google Maps with its own maps app that will include 3D graphics.

According ANI, both the 11 and 13 inch models of the MacBook Air are also expected to get a visual makeover with Retina displays and performance upgrades, report also said that Apple's desktop computing options, the iMac and Mac Pro will be updated.
