VoiceOver is a system that allows people with visual impairments to navigate the touchscreen of an iOS device. Switch it on and your iOS device speaks to you, telling you what's under your fingers as you touch areas of the device. As before, VoiceOver requires that you use gestures in a different way than you would with the feature switched off. For example, to activate an item, you double-tap it. To scroll a page, you flick with three fingers.

The VoiceOver screen includes multiple functions. The first, Speak Hints, is an On/Off option. When on, VoiceOver will provide some additional detail on how to use a button or feature you've selected. The slider below the Speak Hints entry allows you to adjust the speaking rate of the VoiceOver voice.

The next area includes feedback options. The Typing Feedback screen, which you access by tapping the Typing Feedback button on the VoiceOver screen, is where you determine how the device indicates what you've typed. You can choose to have the typed characters, words, or words and characters spoken to you when you're using either or both a software and hardware keyboard. Below this item are three On/Off options--Use Phonetics, Use Pitch Change, and Use Compact Voice (the last of which is new with iOS 5). Each determines the character of the spoken voice.

The Braille command includes a new option. In addition to support for Contracted Braille and the Status Cell option, there's now support for eight-dot Braille devices.
