To turn off the VoiceOver feature of an iPhone, tap Settings, tap General, and tap Accessibility on the iPhone. On the Accessibility screen, tap VoiceOver under Vision, and slide the switch next to VoiceOver to the Off position to disable this feature.
Alternatively, connect the iPhone to a computer with iTunes installed. Open iTunes, and select the iPhone under device. Go to the Summary pane, and click Configure Universal Access at the bottom. De-select VoiceOver, and click the OK button. If you have turned on the accessibility shortcut feature on the iPhone for VoiceOver, you can disable VoiceOver by pressing the Home button quickly three times.
