Please help me with the code that how to pause the stream and again on resume the captured voice append to the existing stream.

Answer: 
Not sure why this had been down voted. Have a look at [this sample](http://code.msdn.microsoft.com/Media-Capture-Sample-adf87622), it should get you started.
The sample linked above provides indeed a good start about how to work with audio/video capture within a WinRT app.
However, there's no scenario in the samples replying the original question:
It seems indeed there are no methods that support pausing in MediaCapture.
The only Store App available that supports pausing while recording that I can see it's [Windows Sound Recorder from Microsoft](http://apps.microsoft.com/windows/en-us/app/9f03273f-fe0b-4ed8-9bc8-c2f256375490).
I assume that App is written in C++ and uses a custom sink instead to record audio which also supports appending data to an existing stream.
