Accessibility and Text-to-Speech
This page is outdated. Accessibility support is not complete and therefore disabled.
SumatraPDF prerelease supports experimental UIA accessibility API, which allows for example screen readers to read out loud the selected text in document.
Accessibility in SumatraPDF plugin
Accessibility features are considered experimental and accessibility is not enabled at the moment in the SumatraPDF plugin.
Usage
Microsoft Narrator
- Start Microsoft Narrator
- Start SumatraPDF
- Open document in SumatraPDF
- Select text. Microsoft Narrator will now read out the selected text.
Known issue: Sometimes Narrator does not read the selection. This seems to be a focus related problem and selecting another window and then back the SumatraPDF window may fix the problem.
