A downloaded e-book can be read aloud in the Macmillan Learning e-book app.
You will first need to download the e-book into the app by following the instructions for LaunchPad or Sapling Learning.
Tap on the icon of your e-book to open it in the app. Navigate to the chapter or page number you need read aloud to you.
At the bottom of the screen is a toolbar. You may have to scroll up for it to appear. Tap on the three dots (...) to open a menu. Tap the Read Aloud toggle to turn it from Off to On.
Controls for reading aloud will appear at the top of the screen. Press the play button to begin the reading. The play button becomes a pause button.
You can slow down or speed up the reading by selecting a speed from the Speed drop-down.
