Question details
The user wants to know why the NVDA screen reader reads long PDF alternative text in fragments and how to make it read continuously.
- Product
- Device & OS
- not provided
- Scenario
- Navigating a PDF document containing images with long alternative text using the NVDA screen reader.
- Observed behavior
- NVDA reads the graphic description in several pauses or fragments when using line-by-line navigation, making it sound interrupted or repeated.
Ensure you have the latest version of the NVDA screen reader installed and that your PDF document is properly tagged for accessibility.
Use NVDA's Continuous Reading Command
Switch from line-by-line navigation to continuous reading to prevent NVDA from breaking up long alt text.
When navigating a document line-by-line, NVDA treats each line as a separate chunk of text. For long alternative text descriptions, this results in unnatural pauses. Using the continuous reading command forces NVDA to read the entire block of text without stopping.
Open your PDF document and use your standard navigation keys to reach the image containing the alternative text.
Instead of pressing the Down Arrow key alone, press the NVDA modifier key (usually Insert or Caps Lock) plus the Down Arrow key.
Listen to the alt text to confirm it is now being read continuously without interruptions or fragments.
Test the PDF with Other Screen Readers
Determine if the issue is specific to NVDA or a problem with the PDF's tagging structure.
Check NVDA Document Formatting Settings
Modify NVDA's preferences to ensure it handles document formatting and long text blocks correctly.

NVDA may break up long alt text if you are using line-by-line navigation (pressing the Down Arrow key). The screen reader treats each line as a separate chunk, causing pauses. Using the continuous reading command (NVDA + Down Arrow) usually resolves this.
How do I add alternative text to images in a PDF?
To add alternative text, you typically need a PDF editor. Right-click the image, select 'Properties' or 'Edit Alt Text,' and enter a descriptive summary of the image for screen readers to read.
Does WPS Office support reading PDFs with screen readers?
Yes, WPS Office's PDF reader is compatible with standard screen readers. It allows users to navigate through text, headings, and images with alternative text for an accessible reading experience.
What is the NVDA modifier key?
The NVDA modifier key is a specific key used in combination with other keys to execute NVDA commands. By default, it is either the Insert key (on the Numpad or standard keyboard) or the Caps Lock key, depending on your initial setup.
