Question details

- Product
- PDF Editor / Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Editing tagged PDF documents for accessibility compliance and testing them with screen readers.
- Observed behavior
- Screen readers fail to correctly pronounce content because the PDF software drops or misinterprets language settings applied to specific child tags.
Before troubleshooting, confirm the original software used to create the PDF (such as Word or InDesign) and identify the specific screen reader and operating system you are using to test the document.
Inspect and Reapply Language Attributes in the Tags Panel
Manually verify and reapply the correct language attributes to the affected child tags using the PDF editor's accessibility panels.
Language tags can sometimes be dropped or altered during the editing process. Manually checking the Content and Tags panels allows you to isolate and fix the missing attributes.
Launch Adobe Acrobat Pro, open your affected PDF, and navigate to the Tags panel from the navigation pane.
Expand the tag tree and locate the specific child tags, such as Span tags, that correspond to the text being mispronounced.
Right-click the problematic tag, select Properties, navigate to the Language tab, and set the correct language code.
Save the document and test it using more than one screen reader (e.g., JAWS, NVDA, or VoiceOver) to verify the language settings are correctly interpreted.
Verify Language Settings in the Original Creation Software
Ensure the language formatting is properly applied in the source document before exporting it to a PDF.

Frequently Asked Questions
Why do screen readers ignore PDF language tags?
Screen readers may ignore language tags if the attributes are improperly nested, if the PDF editing software failed to preserve them on specific child elements like Span tags, or if the screen reader itself does not fully support the PDF structural tree.
Does the operating system affect how PDF language tags are processed?
Yes, the interaction between the operating system, the PDF viewer, and the screen reader can vary. Accessibility APIs differ between Windows and macOS, which can result in the same PDF being read differently depending on the environment.
How can I verify if my PDF has the correct language tags?
You can verify language tags by using the Tags or Content panels in professional PDF editing software like Acrobat Pro. Right-click the document tags, check the Properties, and ensure a valid language code is assigned. Always verify by testing with actual screen reader software.
