Back in June,  9to5Mac  reported  that Apple would offer a feature-rich  voice recognition service in a future version of iOS called Assistant.  Since the  acquisition  of Siri and  partnership  with Nuance, it has been rumored that Apple was planning to offer voice-related features in iOS. However, at WWDC 2011, Apple didn’t mention any such features during the iOS 5 demo. Earlier last week, 9to5Mac once again revealed a few more details regarding Apple’s new “Assistant” feature.

Today, based on this information,  MacRumors  drew a mockup  that claims to show off how the feature will work. Also, MacRumors  contracted Jan-Michael Cart to create a video that shows how the feature might work.Assistantis supposed to take voice data and user specific information to provide an amazing service to the user. In addition, it will also apparently integrate a system in which that can ask the  user questions to clarify and refine its understanding of what is being requested.

The video shows that the feature will be activated by holding down the home button on the iPhone to display a microphone on the bottom of the screen. Once the microphone is displayed, users will be able to speak to their handset and operate it handsfree.  The “Assistant” feature is rumored to be exclusive to Apple’s next-generation iPhone. In addition, the video shows the iPhone pull up a summary of data and pictures on the ISS automatically from Wolfram Alpha.

Apple is expected to unveil its next-genration iPhone and  iPod touch  on October 4th,  during a press event. Numerous rumors have suggested that these would be an iPhone 4Sand an  iPod touch  with 3G capabilities (which I don’t see happening).
