    • Intercoastals and accessory muscles life the ribcage and the sternum swinging ribs up and out increasing size of thracic cavity
    • Lung volume expands
    • Air rushes in due to negative air pressure
  11. How do vocal folds vibrate?
    • Air from lungs blows vocal folds apart
    • Vocal folds quickly close due to elasticity of VF and Bermouli effect
  12. Resonance
    Vocal tract assumes a unique shape for each phoneme which produces a unique vibration pattern for the production of each phoneme
