Setting Reading preferences
You can use the Reading preferences to determine how documents are read by screen
readers or the Read Out Loud feature, and in what order. Set the volume and speed, and
choose between voices that come with the system or that are installed with speech engines
(such as SAPI 4 and SAPI 5 on Windows).
Note: For information on other preferences that affect accessibility, see Accessibility
options .
To set preferences for reading text out loud:
1. Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS) and select
Reading.
2. Choose a reading order option, and choose whether to override the reading order in tagged
documents. (See Selecting a reading order .)
3. If you use a screen reader, select the options you want. (See Accessibility options .)
4. If you use Read Out Loud, select the settings you want for Volume, Voice, Pitch, and
Words Per Minute. Then, select Read Form Fields to have the Read Out Loud feature read
text fields, check boxes, and radio buttons in fillable forms.
Note: The Pitch and Words Per Minute options are available only when you deselect Use
Default Speech Attributes.
