Jeg tror måske du kan få noget ud af at læse/køre denne guide igennem men vil ikke love noget:

Verifying Your Document Text
After you have performed OCR and addressed all the suspect characters, you can do a quick check to insure that the text of your document is available to screen readers: Save as text (accessible).
1. From the FILE menu, choose "SAVE AS"
2. In the "SAVE AS" dialog box, change the "SAVE AS TYPE" to "Text(Accessible)(*.txt)"

3. Click SAVE. Adobe converts your document to a plain text file using the same text that would be accessible to assistive technology, including alternative text for images and graphics.
4. Open your newly saved text version in Adobe. Compare the text in the plain text version to the text in the PDF version are they the same? If not, edit the text and/or edit the tags in the PDF version and re-save as "Text(Accessible)" to check again.
