In this demo, I show you how to keep listening to an eBook such as an iBook or Kindle book even when your screen is locked using the "speak screen" function that you will find in Settings, General, Accessibility, Speech, Speak Screen.
In the demo, I show you two ways of invoking speak screen: either by two finger swipe down from the status line if using VoiceOver or asking Siri to "speak screen".
You can also get Siri to stop speaking the screen if you wish.
