A user reports the following, I will repro:  

many times I'm in an android app and I prep the shortcut to get on the shelf.
ChromeVox says:
"Alert! Change shortcut, the shortcut to show the inbox option menu in the shelf has changed, use search + shift + k instead of shift + alt + k.

He keeps saying this within a period of about 30 seconds repeatedly.

Usually happens when I'm in an android application and I search + k to enter the talkback settings, when I leave that window it starts to speak the message quoted.
Or when I'm in an android app and I'd shift + alt + l to get on the shelf.

Turning ChromeVox off and on again does not work.

I have to leave the system and come back to him to stop giving this message.
Please correct this problem.
