Had to make an account just for this post
three fast points
The brief mode seems to be capable of disabling the ok feature but is not in the states as far as I'm aware at least I cant find it in the settings and trust me I have been looking like a mad men
The original question is straight to the point, why do I need sound responses if it does not overwrite the annoying OKAY, which in it self is a sound response, you cant tell me they design this setting thinking "you know what Alexa shouting OKAY just does not cut it, what if we add a beep at the end and the anoying shouting." come on now.
Lastly, second comment lad, you are just being rude, you know it, not cool, poster does not need to apologize for that kind of behavior
