This document discusses vocalization techniques for public speaking, including energy and emphasis, pitch inflection, rhythm and pacing, pauses and silence, and vocal quality. It provides tips for adding energy and emphasis when speaking, such as energetically reaching out to the audience and emphasizing important ideas. Pitch inflection, or changing pitch, helps avoid monotony. Rhythm can be applied in a speech similarly to how it is used in music or stories. Pacing is important - speaking too fast causes adrenaline to kick in while too slow loses audience interest. Purposeful pauses also impact the audience.
