There is no apparent way to stop Orca

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this bug in Ubuntu 13.10.

As workaround I found that you can turn off screen reader in System Settings -> Universal Access -> Seeing -> Screen Reader (Alt+Super+S).

Behaviour still exists. Ubuntu 13.10 all updates installed.

To add to what Vladimir Rutsky has said, you may need to first turn the reader on, before turning it off. So it is already reading, but you first press Alt+Super+S to start it (again?) and then again to turn it finally off.

very stupid program does not help anything.

Hello,

This problem still exists in 14.04.

Alt+Super+S shortcut as suggested by Vladimir Rutsky works.

I am running Fedora 20 with Cinnamon.
Only way I have found to stop Orca is

killall orca

in terminal

I am running Ubuntu GNOME 15.04, and all I am able to do to stop it is to kill its process, but it carries on talking even after it is dead! That is, it finishes its sentence in protest... But some way of exiting it other than that would be nice...

Me too........very painful experience...going to attempt logout as fiddling with "universal access" was useless.Keeping my fingers crossed........

ubuntu 14.04 TT ...shes not close and need pitch control

good diction and agreement in scores but still do not know rewrite the text.

Unable to turn off the Orca screen reader on login screen, tried editing the .desktop file from etc and disabling it from settings, but it wakes up every time on login screen. Text pronounced are "Turning screen reader off, turning screen reader on ..." and it goes on.

Please fix this, for now i am uninstalling the application.

Behavior still exists... `killall orca; apt remove gnome-orca` was my approach. Would've kept it installed if there was some way to stop it without resorting to killall.

Still a bug in 19.04. Accidentally triggered the screen reader, absolutely no way to kill it in an obvious manner. I had to google for what the screen reader is on Ubuntu to start with. No icons, no warnings, nothing at all. In the end got rid of it by killing and permanently removing it. Good riddance.

This behaviour can't be the default. Please fix it.

I had the most nightmarish experience yet: Somehow (probably by accidentally typing the shortcut) I turned on Orca, but because my computer's sound was muted, I only got mysterious symptoms. PDF files in Firefox kept returning to the first page, TeXstudio would crash with a segmentation fault when I opened the file manager, and I feared that my CPU was about to die. Finally, after plugging in headphones to listen to a video, I heard the jabbering and opened the System Monitor to find out the name of the program causing it. Please add an Orca icon to the system tray to help users to fix this faster!
