Summarize the following:
Take a moment to notice the quality of your breath. Notice if you are breathing in through your mouth or through your nose. For now, don’t try to change your breath. Just notice how it feels and breathe naturally. Try breathing in through your nose and down into the lower depths of your belly. Then, while you are exhaling, say “hello.” Listen to the pitch and depth of your voice. To compare, try the same exercise but breathe into your chest or your throat. It should sound very high pitched when you breathe into your throat, medium pitched when you breathe into your chest, and deep when you breathe into your lower diaphragm. Breathe deep into your lower diaphragm. As you exhale, say something you want to say. Your voice will sound deeper if you breathe into your lower belly.  Open your mouth quite naturally, in order to speak normally. Do not purse, cup or shape your lips or cheeks.
Breathe naturally. Experiment with your breath. Use diaphragm breathing.
