If you have been annoyed by this following dialog when you open PDF files in Adobe Acrobat v8, here
are the two different ways is the way you can disable it.
- Rename the Accessibility.api and ReadOutLoud.api to Accessibility.old and ReadOutLoud.old (or you can move them to a different folder). These files are found in C:\Program Files\Adobe\Acrobat 8.0\Acrobat\plug_ins. This solution however, has the possibilty that a future upgrade of Acrobat would cause these plugins to renable.
Remove “Speech Recognition” from the Language Tool bar, settings, Installed Services. The other way to get this, if you don’t have the Language Toolbar visible, is via the Regional and Language Options Control Panel, under the Languages Tab, and click on the Details button and then you can remove any references to “Speech Recognition” that you find under the Installed Services.
