Twitter user Chronic, a past source of Apple leaks, posted a couple of interesting notes this weekend pertaining to iOS 5 and the iPhone. In one post, he links to a pair of screenshots purportedly from an iOS 5 device showing Internal Settings menus that contain options related to Nuance speech recognition technologies.
