The upcoming iPhone OS 3.0 for Apple's iPhone was rumored a while ago to feature voice control. Well, Ars Technica has found a bunch of new clues that support this being included, and throw some further juicy details into the mix. Apparently a range of various voice-related features, codenamed "Jibbler", will be included with the operating system currently in development.
"Jibbler" will have a range of features, according to Ars; one of which will be voice recognition. A user could use the iPhone's microphone, or a pair of Apple headphones with the same feature, to input voice and have Jibbler interpret it. Another feature that could be included alongside this is voice synthesis. This would be similar to what Apple's most recent iPod Shuffle offers, but "the difference being that the iPhone hardware itself could handle real-time voice synthesis."
It's hinted that Apple may also include these features in their official SDK, as there have been the following classes and methods found: "VSSpeechSynthesizer, VSRecognitionSession, SBVoiceControlDisableHandlerActions, SBSensitiveJibblerEnabled, and SBVoiceControlSoundCompletion. SB refers to SpringBoard, and VS likely refers to Voice Services." It would be excellent to have a native ability to voice-dial a person, as opposed to have to use a third party application, and these items found only add to the chance of it becoming a reality.
