Keep in mind how high, low or loud your voice is (volume) and how it rises and falls while you talk (pitch). Projecting doesn’t mean shouting: it means adding energy and life to the voice and body.
Use volume to draw attention to important sections of your talk, either becoming quieter to draw your listeners in, or becoming louder to emphasise a point.
