Two new options have been added to the VoiceOver settings page in the Settings app. Languages and dialects, and Large Cursor
Languages and Dialects
VoiceOver in iOS6 had an option called Language Rotor, which let users place their favorite languages on the rotor. In iOS 7, Languages and Dialects contains settings for switching the default VoiceOver voice, and to add multiple languages to VoiceOver. There is also an option to download the enhanced version of that voice, and iOS will even report the size of the enhanced voice.
When VoiceOver is focused on content or controls, a small box is shown around the focused item. This is called the VoiceOver Cursor. The Large Cursor setting transforms the VoiceOver cursor into a thickly lined box with a red border to emphasize focus.
