Humming will help you strengthen and control your vocal folds. You'll need about five minutes of uninterrupted time to complete this exercise. Make sure that you follow the steps in order, and repeat them three times throughout the day.

• Inhale, taking in your usual amount of air.
• Exhale slowly, saying the word "hum" at your normal volume.
• Exhale evenly to maintain the volume and quality of the hum.
• Take note of any extra notes with your hum – such as a flutter sound– if you relax the tension or lose control as you exhale.
• Repeat the humming and be sure to keep the extra notes out of your voice.
