What happens when you breathe?
Diaphragm contracts when inhale, ribs move upward and out increasing the size of the
chest cavity
Air flows into the lungs and fills the vacuum
When you exhale the diaphragm slowly begins to relax, and abdominal muscles exert
pressure upward to force air out of the lungs
Types of Breathing
If you gasp for air/ raise shoulders = clavicular breathing (happens from the top of
Causes tension in neck and throat (avoid this type of breathing)
Diaphragmatic breathing = produces steady breath from the diaphragm and also

emotion in voice)
Do not use a speech pattern or same cycle of inflection

Don't rush/ go to slow
Most desirable rate is 125-150 words per minute
Breaks/interruptions in a speech that separate thoughts/ideas
Dramatic pauses: intentional breaks/silences between ideas that can bring out the
meaning of a specific passage
Vocalized pauses are fillers- verbalizations like “uh’ ‘um’ ‘like’ ‘so’ etc
