How to measure the effectiveness of communication
Hear the responses listeners give you.
If your audience (be it one person or many) tells you they don't understand what you are saying, hear them. Many a good point is lost on listeners when a speaker refuses to stop pressing on with their speech to clarify a point they've made.

Options are:
A). Oftentimes, good listeners wait for somebody to finish what they have to say so that it seems like they are explaining, rather than you dragging out the main points in your speech. Often, good listeners have experienced moments in their life that were unclear.
B). Stop and clarify what you are saying even if it means it'll take longer to make your point (s). Don't take yourself, or your ideas, too seriously.
C). Speaking in one voice means changing what you are about to say. This way you can be heard clearly when you need to come up with a new word, changing your pitch, etc.
D). Many times, a feedback editor will speak to greet listeners, not answer questions face-to-face. Questions them might ask in a professional tone could come across as push-away.
B).
