Physiology of Articulation

Airstream directions ingressive (in) vs. eggresive (out)
Airstream mechanisms pulmonic, esophageal, glottal and velar
Eggresive pulmonic: normal talking
Ingressive pulmonic: talking while bringing air in (vocal folds STILL vibrate)
Eggresive esophageal: burping speech
Eggresive glottalic: air escapes when closed glottis is raised- used in ejectives of African and Native American languages
Ingressive glottalic: air pushed in when closed glottis is lowered- these stops are called implosives and are used in India and Pakistan
Eggresive velaric: tongue is raised and air escapes- Donald Duck speech
Ingressive velaric: tongue moves and as air flows inward it creates the "clicking" sound used in many African languages
Four primary stages of swallowing: oral preparatory, oral, pharyngeal and esophageal
What happens in the oral preparatory stage of swallowing? chewing of food, forming a bolus, raising the tongue posteriorly
What happens in the oral stage of swallowing? tongue drops down and pulls back to move the bolus toward the faucial pillars
What happens in the pharyngeal stage of swallowing? 1)soft palate elevates and closes the nasopharynx 2)respiration ceases 3)vocal folds close 4)false vocal folds adduct 5)epiglottis folds down
What happens in the esophageal stage of swallowing? esophageal sphincter opens (involuntary)
