When talking to Alexa from other room or place where you can’t see if Alexa hears you or not. It would be nice if you could make Alexa respond “Yes” when you call her and then continue with your command.
This way you can hear when Alexa is really listening your requests.
There is a setting which makes small sound when Alexa reacts, but it is so faint that you can’t hear it to another room. A proper “Yes” would do the trick.
