Read It Your Way
To customize Read Aloud
preferences, choose Edit >
Preferences (Acrobat > Pref-
erences), and choose the
Reading heading in the Cat-
egories list. Look for these
options:
•
Choose an option for
Reading Order, the
method in which Acro-
bat automatically moves
through a document.
The default, and rec-
ommended option, is
"Infer reading order from
document. "
•
Define whether you want
the screen reader to read
only the currently vis-
ible pages, the entire
document, or the cur-
rently visible pages in
a large document. The
default size for defining
a document as "large" is
50 pages; type a differ-
ent number to change
the definition of a large
document.
•
In the Read Out Loud
Options section, set a
volume, and choose a
voice, pitch, and speed.
Both Windows and Mac
offer several voices—on
Mac some of them aren't
even human!

Using a mouse isn't the only way to move around a page. Acrobat can also
magnify and reflow documents, automatically scroll, read the page aloud,
or enable the use of keystrokes.
Magnification and reflow. For some, it's important to zoom in to a
very high magnification in order to read the screen. Acrobat offers reflow,
which wraps text automatically regardless of the magnification. Reflow is
great if you are reading a single column on a page. For complex layouts,
you need to define articles, which create a reading path through a docu-
ment. Read about reflow in the sidebar "Wrapping with Reflow"; read
about articles in the sidebar "Organize Reading with Articles. "
Automatic Scroll. Use scrolling when you're looking for a particu-
lar element such as an image. Choose View > Automatic Scroll, or press
Ctrl+Shift+H (Command+Shift+H). The scrolling starts at the current
location in the document, and stops when you reach the end of the
document.
Automatic scrolling uses Continuous page layout. To change speed,
press the up arrow key to increase or the down arrow key to decrease, or
you can type a number from 0 to 9—the higher the number, the faster
the speed. Want to reverse? Press the minus key (–) on the keyboard or
number pad; press Esc to stop the scrolling.
Tip
Since Acrobat pauses the scrolling and applies the selected tool if you use
the mouse, be sure the Hand tool is selected. That way, you aren't adding
extra steps to deselect a tool.
Read Aloud. Acrobat can use system resources to read a document
aloud—terrific when your goal is to make your documents more acces-
sible as Acrobat simulates some features of a full-blown screen-reader
program:
•
Choose View > Read Out Loud > Activate Read Out Loud to get started;
choose View > Read Out Loud > Deactivate Read Out Loud to stop.
•
Locate the page you want to read and then choose View > Read Out
Loud > Read This Page Only, or choose View > Read Out Loud > Read
To End Of Document.
Tip
You can also have the voice read a selected object. Click a paragraph on
the page with the Hand tool and it is read aloud.
