VoiceOver describes aloud what appears onscreen so that you can use iPhone without seeing it. VoiceOver speaks in the language specified in International settings.
NOTE: VoiceOver isn’t available in all languages.
VoiceOver tells you about each element on the screen as it’s selected. When an element is selected, it’s enclosed by a black rectangle (for the benefit of those who can see the screen) and VoiceOver speaks the name or describes the item. The enclosing rectangle is referred to as the VoiceOver cursor. If text is selected, VoiceOver reads the text. If a control (such as a button or switch) is selected and Speak Hints is turned on, VoiceOver may tell you the action of the item or provide instructions for you—for example, “double-tap to open.”
VoiceOver plays a sound whenever you change screens, and speaks the name of the initially selected item (typically, the item in the upper-left corner). VoiceOver also lets you know when the display changes to landscape or portrait, and when the screen is locked or unlocked.
