Lung Volumes and Vital Capacity
           Speech Breathing
• More complex than quiet breathing
  – Coordination of breathing with linguistic
    utterances
     • Appropriate place to inhale
     • Appropriate amount of air to inhale & exhale
     • Prosodic variations

B. 20-40
C. 12-18
D. 1-12
E. More than 60

      Life vs. Speech Breathing
• Life                         • Speech
  –   Nose                       – Mouth
  –   Inhale 40% of time         – Inhale 10% of time
  –   Exhale 60% of time         – Exhale 90% of time
  –   10 % of vital capacity     – 20-25 % of vital
                                   capacity
  – Muscles of thorax and        – Thoracic and
    diaphragm                      abdominal muscles

Patterns
        Measurement Devices
• Pneumatochograph used
  to measure airflow

• Plethysmograph suit
  monitors the movements
  of both the abdomen and
  ribcage

• Magnetometer is two coils
  of wire which generate an
  electromagnetic field
                 Diseases
•   Parkinson's disease
•   Cerebellar disease
•   Cerebral palsy
•   Mechanical ventilation
•   Voice problems
•   Hearing problems
