The actions listed in the command are enacted in order from top to bottom. Some actions may have options to wait to proceed until they are completed, such as the 'Say something with Text to speech' action.
You have actions in the order of a TTS action, an action to Stop Dictation mode after that, then an action to Stop Listening followed directly by an action to Start Listening.
You need to consider the step-by-step flow of actions, and order them such that they accomplish your goals in a logical manner. I'm not sure what you are trying to accomplish here, but I'd like to assume you wanted to stop dictation, have text-to-speech say what is in the dictation buffer and fully complete this speech action before continuing onto the next action, and then (maybe?) resume dictation? Not sure at all why the Start/Stop Listening actions are present, or what your goals are for them. It is redundant to stop listening only to immediately start it once again milliseconds later.
Finally, there should be no case where audio from text-to-speech plays out of any Playback device but your Logitech headphones - unless you have some non-standard audio setup that I'm not aware of.
