Accessibility preferences in Reading panel

Reading Order

Specifies the reading order of documents. The reading order preferences also appear in the Accessibility Setup Assistant.

Infer Reading Order From Document (Recommended)

Interprets the reading order of untagged documents by using an advanced method of structure-inference layout analysis.

Left-To-Right, Top-To-Bottom Reading Order

Delivers the text according to its placement on the page, reading from left to right and then top to bottom. This method is faster than Infer Reading Order From Document. This method analyzes text only; form fields are ignored and tables aren’t recognized as such.

Use Reading Order In Raw Print Stream

Delivers text in the order in which it was recorded in the print stream. This method is faster than Infer Reading Order From Document. This method analyzes text only; form fields are ignored and tables aren’t recognized as such.

Override The Reading Order In Tagged Documents

Uses the reading order specified in the Reading preferences instead of that specified by the tag structure of the document. Use this preference only when you encounter problems in poorly tagged PDFs. This preference corresponds to the Override The Reading Order In Tagged Documents option in the Accessibility Setup Assistant.

Page Vs Document

This preference determines how much of a document is delivered to a screen reader at a time. If a PDF isn’t tagged, Reader may analyze the document and attempt to infer its structure and reading order, which can take a long time for a long document. You may want to set Reader to deliver only the currently visible page so that it analyzes only a small piece of the document at a time. This consideration will vary depending on the size and complexity of the document and on the features of the screen reader. When Reader delivers information to a screen reader, screen magnifier, or other assistive software, it loads information into a memory buffer that is directly available to the assistive software. The amount of information that is delivered to the memory buffer can affect how long Reader takes to perform tasks, such as opening the document, advancing to the next page, changing views, and carrying out commands.

Only Read The Currently Visible Pages

This option is usually best when you use a screen magnifier. It improves performance by eliminating the need for the software to process parts of the document that aren’t visible. When Reader sends only the currently visible pages of a PDF to the memory buffer, the assistive technology has access to those pages only. It cannot go to another page until the next page is visible and Reader has sent the page information to the memory buffer. Therefore, if this option is selected, you must use the navigation features of Reader, not those of the assistive technology, to navigate from page to page in the document. You should also set the Default Page Layout option in preferences to Single Page if you choose to have Reader send only the currently visible pages to the assistive technology. Because Reader sends page information about all visible pages, the assistive technology receives information about pages that may be only partially visible (such as the bottom of one page or the top of the next), as well as those pages that are completely visible. If you use a page display setting other than Single Page, such as Continuous, and then you display the next page, the technology may not correctly track which portion of a previous page it has already read aloud. For instructions on setting the default page layout to Single Page, see Preferences for viewing PDFs.

This option corresponds to the Only Read The Currently Visible Pages option in the Accessibility Setup Assistant.

Read The Entire Document

This option can be best if you use a screen reader that has its own navigation and search tools and that is more familiar to you than the tools in Reader. This option corresponds to the Read The Entire Document At Once option in the Accessibility Setup Assistant.

For Large Documents, Only Read The Currently Visible Pages

This option is selected by default and is usually best if you use a screen reader with long or complex PDFs. It allows Reader to deliver an entire small document but revert to page-by-page delivery for large documents. This preference corresponds to the For Large Documents, Only Read The Currently Visible Pages option in the Accessibility Setup Assistant.

Confirm Before Tagging Documents

When selected, lets the user confirm the options that will be used before Reader prepares an untagged document for reading. Tagging can be a time-consuming procedure, especially for larger documents. This preference corresponds to the Confirm Before Tagging Documents option in the Accessibility Setup Assistant.

Read Out Loud Options

Set preferences in this section to control volume, speed, and pitch of the voice used for Read Out Loud. You can choose to use the default voice or any of the voices provided by your operating system. Select Read Form Fields to have Read Out Loud read the contents of form fields. These preferences don’t correspond to options in the Accessibility Setup Assistant.
