For example, an English document read with French pronunciation rules would sound like nonsense and be unintelligible. Setting the language also ensures that special or foreign characters and scripts are displayed properly in visual browsers.

Section 4.5: Reading Order
After tagging your document, the next step is to ensure the content is presented in the correct order for screen reader users and individuals who zoom in at high levels. This can be accomplished using the Tags and Order navigation Navigation panes. When you’re manually tagging a long document, it’s advisable to check the reading order after you finish tagging each page, rather than all at once at the end. That way, you can fix any problems along the way.

For most simple documents, the easiest way to establish the screen reader reading order is by using the Tags Pane. Carefully review the tag tree to ensure the content flows in a logical sequence. However, for documents that prioritize visual presentation, you may need to use the Order Pane to adjust the reading order. The good news is that if you create a document with accessibility in mind from the start, you’ll likely achieve a reliable reading order and only need minor adjustments afterward.  |

Evaluate the various types of content in the document and determine their logical reading sequence. For example:
Ensure the reading order supports clarity and comprehension for all users. |

However, if you prefer to remove them individually, you’ll need to do so manually within the tag tree. Exercise caution when using the automatic feature, as not all empty tags are truly empty; some may need content to be added.
