On the back of a report from several weeks ago, Ars Technica is providing further details about a feature which is reportedly codenamed “Jibbler”.

According to Ars “Jibbler” will primarily deal with voice recognition and synthesis.

Not much information is known at this time, but according to our own people familiar with the matter, Jibbler appears be an enhancement to the iPhone SpringBoard application, the Finder-esque app that acts as a launcher and will support the newly announced 3.0 Spotlight search. Jibbler may be controlled via the iPhone headset—button squeezes could be used to record short voice segments from the user, which Jibbler will then interpret. Voice synthesis can then be used to give the user a response, similar to the latest generation iPod shuffle, which can “read” playlists and track names—the difference being that the iPhone hardware itself could handle real-time voice synthesis.

Ars speculates that he feature could bring voice dialling to the iPhone but also that Apple could allow access to the feature via the iPhone SDK.
