My Echo sometimes says things for no reason. We've noticed that music will start playing with no sign that the Echo was processing a command. Other times it will say part of a phrase and go silent. If you ask to repeat it doesn't know what the last command was to repeat. This happens nearly once a week. The most notable issue is that when you talk to Alexa it beeps to let you know it's listening. When these random words or actions happen there is no beep that she's processing a command. Just a sudden unexpected random response. Is there a way to see if an incoming command told it/her to say something?
