9to5Mac: Apple is testing a local, offline version of Dictation voice input for iOS devices, according to strings of code found inside of the iOS 7 beta. The code, which was discovered by Hamza Sood, is located inside of both iOS 7 betas, but it is not present in iOS 6. Currently, when an iOS user uses their voice to input text using Dictation, the iOS device will use software that uploads your speech to the cloud to be converted into text.
