cannot stop mac from speaking text.

[inscrewtable]

I have set a keyboard shortcut cmd opt ctrl + S to start speaking highlighted text which works fine, however I have set numerous keyboard shortcuts but nothing I do can stop the text speaking, even quitting the application or relaunching the finder. In the end I have to log out to stop it speaking.

What's going on here?

thx
