Apple may have recently doled out its iOS 5.1 Beta 3 with 3G toggle to developers on Monday, but further examination of the firmware file's third build revealed references to Siri Dictation.

9to5Mac apparently spotted a new section labeled About Dictation and Privacy in the keyboard menu, while working on the iPad. Once opened, the same standard literature and feature information related to Siri appears. The feature, available only on the iPhone 4S, is said to appear on Apple's latest-generation iPod Touch as well, the technology publication said on Monday.

The iPhone 4S, however, does not include the tab marked About Dictation and Privacy in the keyboard settings panel. The fact that it's in a different location could mean that the feature is not ported over code from the iPhone 4S, which in turn could mean that the iPad could just get Siri Dictation.

Although Dictation is not actually functional on the iPad 2, 9to5Mac speculates that the new feature of the iOS 5.1 might eventually launch on the current iPad model, or it could mean an exclusive feature for the upcoming iPad 3.

The publication also added that the Cupertino company was rumored to be working on a full version of Siri for the iPad.

It appears that Apple has not commented on these speculations as yet.
