This is part 1 of a 2 part rule. It is an example of how to execute sequential, timed actions. If you place your device face down it will turn the text to speech (ie music stream) volume to max and say "say something". Then it enables the second rule to turn the volume down to 50% and disables itself. Note that the delayed exec time of rule 2 should be longer than it takes to say the text. This technique can be used for any desired sequential actions.
