Inhalation
Relaxation of intercostal muscles, lowering of diaphram
Exhalation
Raising of the diaphram and tensing of intercostal muscles
Pulmonic ingressive airstream
Esiohageal aistream, generally for people, outwords, egressive pulmonic is outwards
Esophageal egressive
Burping
Larynx
The focal folds, a structure atop the trachea that is responsible for air passage during breathing, protecting the airway when swallowing and sound production
Focal folds
Do not move fast enough for speech, thus requires Bernouilli principle
Bernouilli principle
Faster moving air has lower pressure: Vocal folds moving together (tensely) causing fast airstream that forces them apart, the low pressure gives a suction effect causing them to move together again (closing finished a single pulse/vibration)
Vibration principle
The more vibration, the higher the pitch
Classification of voice sound
- Voiced or voiceless
- Place of articulation
- Manner
Nasality
Way of articulation, velum is down and they are always considered stops
Laterality
At some point in the mouth there is closure, but air still escapes over the sides of the tongue
Oral
Velum is up, all sounds except nasals
Central
All sounds except for the laterals
