Weird Keyboard speech activity.

Since I have had my new iMac i27, I notice every so often that when I press a key (seems random) I hear a “curious” coming out of the speakers or when I use ” I hear a noise. I have checked the system preferences and do not have the anything in there that appears to be the cause. It is obviously some app running but it beats me which one it is.

Does anyone have any suggestions for trying to locate what app may be causing this?

 

universal access is off.

I located the source. It is the program called Spell Catcher. When I disabled interactive features it stopped alerting me that I spelled the word wrong.
