How to use the accessible PDF
Open the PDF in Adobe Reader. Go to menu bar and click on View > read out loud > activate read out loud. The audio voice you will hear is dependent on the computer or device that you are using to read the book. To read the text with, for example a Scottish voice, you need voices on your computer. Schools, pupils and anyone else in the public sector can download the voices free of charge, for Mac and PC, from The Scottish Voice.
If you are using Adobe XI Read out Loud you can change the voice by going to edit > preferences > reading.
