I created and interactive PDF via InDesign file (CS5.5). When I open up the PDF in Acrobat (X/10.1.4) and select the "Read Out Loud" function, it will only work if I click on a line of text inside the PDF. But even then, it will only read one line at a time for every line I click in.
I selected "Read this Page Only" and "Read to the End of Document" and nothing happens.
