Default [Q] Cyanogenmod 11 -accessibility problem (stop voice activation!)

Dear all,

I have a serious problem. I have activated the speaking (for blind people) option from the accessibility button in the option menu (dont ask me why). Now I hear a loud voice repeating every step or button I press. I cannot turn it off. When I go the option menu I cannot scroll down in order to get to the accessibility button to switch the voice activation (for blind people) off.

I have downloaded Cyanogenmode 11 for samsung galaxy s4 I9505.

Does anyone know how to solve this? Is there another way to get to the accessibility button?

Thanks in advance!
