Apple’s iOS devices (iPhone, iPad, iPod, and Watch) come with accessibility features built-in. The purpose of this document is to give the blind or low vision user a concise introduction to the accessibility features offered on iOS devices.


An Introduction to VoiceOver

  • VoiceOver is a "screen reader"; it reads text aloud on the screen.
  • To enable VoiceOver, go to Settings> General> Accessibility> VoiceOver.
  • You can also tell Siri, “Turn on VoiceOver.”

Navigating the Screen with VoiceOver

  • To hear VoiceOver speak an item, tap it with one finger.
  • To activate an item, quickly double tap it with one finger.
  • Navigate the screen by swiping left and right with one finger or exploring by touch.
  • To scroll, swipe with three fingers.
  • To go back a screen, use a left-to-right two-finger "scrub" gesture.
  • To perform a "say all" and read everything on the screen, swipe down with two fingers.

Typing with VoiceOver

  • Locate the desired letter on the on-screen keyboard, either by swiping or exploring by touch.
  • Double-tap the desired letter to enter it.
  • Holding one finger on the desired letter and single-tapping the screen with another finger also works and may be more convenient. This is called a “split-tap” gesture.
  • If a mistake is made, double-tapping the “Delete” button will remove the character.
  • Other typing options are available, such as Braille Screen Input, Handwriting Mode, and Touch Typing Mode.

VoiceOver Settings

  • Access all VoiceOver settings in Settings> General> Accessibility> VoiceOver.
  • Speaking Rate: Adjusts the speaking rate of the text-to-speech voice.
  • Speak Hints: Toggles whether VoiceOver provides hints on navigating the interface; good for beginners.
  • Use Pitch Change: Changes the pitch of the text-to-speech voice for hints, capitalized, typed, and deleted letters.
  • Use Sound Effects: When enabled, VoiceOver plays a sound when one moves from element to element on the screen.
  • Speech (Settings): Allows one to change the dialect of the voice and, for devices that support it, the speech synthesizer.
  • Braille (Settings): Allows one to change a variety of Braille-specific settings.
  • Rotor (Settings): Allows one to customize which items appear in the VoiceOver rotor—discussed in the next section.
  • Typing Style: Allows one to choose between Standard Typing (discussed earlier), Touch Typing, and Direct Touch Typing.
  • Phonetic Feedback: Speaks a phonetic word after reading a letter on the keyboard.
  • Typing Feedback: Controls whether VoiceOver speaks characters, words, characters and words, or nothing when they are typed.
  • Always Speak Notifications: Toggles whether VoiceOver speaks the full text of incoming notifications when the screen is locked.
  • Navigate Images: Controls whether VoiceOver skips images when swiping through the screen.
  • Large Cursor: Provides extra visual emphasis as to the location of VoiceOver focus.

The VoiceOver Rotor

  • There are two purposes of the rotor: to change settings quickly and advanced navigation.
  • To use the rotor: place two fingers on the screen, with some space in-between them.
  • Rotate your fingers as though turning a radio dial; this often involves rotating your entire hand.
  • VoiceOver will make a ticking noise as you turn the rotor, announcing various options as you reach them.
  • Commonly-enabled rotor settings include speech rate, typing preference, Braille Screen Input, Handwriting Mode, moving by character/word/line, etc.

Other Helpful Hints for VoiceOver Use

  • Three-Finger Triple Tap: Enables the screen curtain—most useful for privacy. If you have speech but nothing visually displayed on the screen, check this setting.
  • Three-Finger Double Tap: Toggles speech. If VoiceOver is on but you have no speech, check this setting.
  • In some situations the volume of the device can be accidentally lowered, so this is also something to check if VoiceOver is enabled but there appears to be no speech.
  • Four-Finger Double Tap: Enables (and disables) VoiceOver help and is a great way to practice VoiceOver gestures.

Low Vision Accessibility Features

  • Zoom: A built-in magnifier that works across the operating system.
  • Invert Colors: Flips all colors on the screen.
  • Grayscale: Displays the entire user interface in different shades of gray.
  • Larger Text: Allows one to enlarge the font across a variety of built-in and third-party apps.
  • Bold Text: When enabled, makes text thicker across a range of built-in applications.
  • Button Shapes: Makes buttons easier to distinguish from other user interface elements, such as icons.
  • Increase Contrast (Settings): Allows one to customize the visual contrast of the user interface through Reduce Transparency, Darken Colors, and Reduce White Point options.
  • Reduce Motion: Reduces the motion of backgrounds, wallpapers, and other user interface elements.
  • On/Off Labels: Rather than using colors, indicates whether a setting is enabled or disabled with the numbers 1 and 0, respectively.


  • Siri is Apple’s personal digital assistant.
  • While Siri was not designed specifically as an accessibility feature, it can enhance the iOS user experience for blind and low vision users.
  • To use Siri, press and hold the Home button until you hear the device beep. Speak your request, then release the Home button.
  • Siri will speak its response.
  • Press and hold the Home button again to continue interacting with Siri, or press the Home button without holding to dismiss it.

Apps and VoiceOver Accessibility

  • Many, but not all, apps are accessible with VoiceOver.
  • App developers must take specific steps to ensure that their app fully supports VoiceOver.
  • Some apps are not accessible because of their nature, e.g. video games.
  • Inaccessible apps are generally so only because developers are not aware of VoiceOver.
  • Many developers are quite receptive to accessibility improvement requests.
