How to test

The accessibility features and basics of how to test content using screen readers are covered here for Android and iOS. This section will be added to over time.


Accessibility features

Different versions vary but accessibility include:

  • Talkback - speech output
  • Voice search
  • Captions on/off
  • Magnification gestures - triple tap to zoom
  • Large text
  • Auto rotate screen
  • Speak passwords
  • Accessibility shortcut - accessed via the power button
  • Test-to-speech output



Talkback, screen reader output for Android, is supported in versions 2.2 upwards and is available from the Android Marketplace. Version 4, Ice Cream Sandwich, comes with Talkback, Kickback (haptic feedback) and SoundBack (audio feedback) bundled with the OS.

You will need to ensure that Web Scripts are enabled in the Settings and the Eyes-Free-Keyboard is installed in order to navigate web content.

iOS VoiceOver supports explore by touch and gestures. When in web pages or in an app you can use a gesture like turning a dial to bring up a Web Rotor. This is a list of options that you can choose to navigate by - it's similar to how you may navigate by headings, lists or WAI ARIA Landmarks using a desktop browser such as Jaws, NVDA or Voiceover on Mac. A great way of testing how accessible content is for VoiceOver users is to switch off the screen and use screen curtain. You can switch off the display by triple tapping the screen with three fingers.
