How to turn off narrator of Ubuntu?

Recently I downloaded ebook speaker applications from Ubuntu Software Center. After that I'm facing this problem. Whatever I type, it keeps on narrating. I don't which application I've opened. No application seems to be open. I've to mute the speaker. Any solution ?


Solution 1:

System Settings -> Universal Access -> Seeing -> Screen reader -> Off

Or a hotkey "Alt-Super-S"

Solution 2:

I faced the same problem in Ubuntu 14.04 LTS. "Orca Screen Reader" was installed in my laptop, which I realized and uninstalled it. And then the problem was solved.
