In previous versions of iOS, dictating text into an app would send your voice to Apple’s server once you finished speaking to be analyzed and return the converted text. Siri used to function the same way, but with iOS 8 Apple made changes that allowed voice input to be streamed to the server for conversion while the user was still speaking. As of IOS 8 Beta 4, the system keyboard’s dictation feature now works the same way. – Mike Beasley,9to5Mac.com  http://ift.tt/1sGDAnl
