Read Out Loud

I have been making Accessible Forms with Acrobat for a few years. I am fairly new to LCD.

I have a PDF form designed in LCD ES4. I applied roles to the lists and headings, associated table headers and cells, added tooltips or custom text etc.

For generating Accessible Tags, I used the Form Properties Save Option.

I know you cant edit LCD forms with Acrobat, or use the touch up reading order tool etc.

When I look at the properties in Acrobat it says the PDF is NOT tagged.

Read Out Loud just says Warning Empty page.

I am using the Read Out Loud from Acrobat XI.
