Close your lips, say mmmmmmm,… and feel vibration in back of your throat. Now read a couple of sentences on your own and see if you notice that same type of vibration as you reach the end of your breaths. Try it one more time, this time holding your hand about a half inch from your mouth. Pay attention to how much air you feel hitting your fingers. If your sentences end in that gravelly sound, you’ll notice that almost no air is reaching your fingers. Read again and try to keep a consistent flow of air hitting the fingers; when the air stops or greatly diminishes—take another breath.
