The downloadable pdfs of the Report include an accessibility layer for use with screen reader tools.
Accessibility support features are available in Adobe Reader, however the features may vary according to the version of Adobe Reader you are using. Versions 6.0 and above include a text-to-speech converter called 'Read out loud'.
To get the most benefit from the accessibility layer, we recommend that you download the most recent, full-product version of Adobe Reader, and set it up to open in a separate Adobe Reader window, rather than in your browser window.
