1. Start the Accessibility Setup Assistant by selecting All tools > Prepare for accessibility > Use setup assistant.
Acrobat provides several preferences that help make the reading of PDFs more accessible for visually impaired and motion-impaired users. These preferences control how PDFs appear on the screen and how they are read by a screen reader.
Most preferences related to accessibility are available through the Accessibility Setup Assistant, which provides onscreen instructions for setting these preferences. Some preferences that affect accessibility aren’t available through the Accessibility Setup Assistant including preferences in the Reading, Forms, and Multimedia categories. You can set all preferences in the Preferences dialog box.
The names shown for some preferences in the Accessibility Setup Assistant are different from the names for the same preferences shown in the Preferences dialog box. Acrobat Help uses the names shown in the Preferences dialog box.
For more information about accessibility features, see www.adobe.com/accessibility.

Accessibility preferences in Documents panel
Automatically Save Document Changes To Temporary File Every When deselected, this preference disables the auto-save action. Each time a PDF is saved, the screen reader or magnifier must reload the document. This preference corresponds to the Disable Document Auto-Save option in the Accessibility Setup Assistant.
Accessibility preferences in Forms panel
Fields Highlight Color and Required Fields Highlight Color These preferences specify what colors are used to highlight fillable form fields. They correspond to the Field Highlight Color and Required Field Highlight Color options in the Accessibility Setup Assistant.

Accessibility preferences in Multimedia panel
Show Subtitles When Available
Play Dubbed Audio When Available
Show Supplemental Text Captions When Available
Show Audio Description (Or Video Description, Or Descriptive Video) When Available
These preferences don’t correspond to any options in the Accessibility Setup Assistant.
Accessibility preferences in Page Display panel
Zoom Sets the onscreen magnification of documents and allows low-vision readers to read reflowed PDFs more easily. This preference corresponds to the Override Document Zoom option in the Accessibility Setup Assistant.
Smooth Text Controls anti-aliasing of text. To disable smoothing of text and make text sharper and easier to read with a screen magnifier, choose None. This preference corresponds to the Disable Text Smoothing option in the Accessibility Setup Assistant.
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 what the tag structure of the document specifies. 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, Acrobat may analyze the document and attempt to infer its structure and reading order. This process can take a long time for a long document. Consider setting Acrobat to deliver only the currently visible page so that it analyzes only a small piece of the document at a time. This consideration varies depending on the size and complexity of the document and on the features of the screen reader. When Acrobat 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 Acrobat 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 Acrobat 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 Acrobat has sent the page information to the memory buffer. Therefore, if this option is selected, you must use the navigation features of Acrobat, not the features of the assistive technology, to navigate from page to page in the document. Also set theDefault Page Layout option in preferences to Single Page if you choose to have Acrobat send only the currently visible pages to the assistive technology. Because Acrobat 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 Acrobat. 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 Acrobat 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 are used before Acrobat 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 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 that your operating system provides. You can also use the up and down arrows to read blocks of text. These preferences do not have corresponding options in the Accessibility Setup Assistant.
