Approximants Flashcards
Initation (approximants)
Pulmonic, egressive ASM
Articulation (approximants)
Open approximation - maintained or momentary
Approximants production
Articulators not close enough for turbulent airflow
Intra-oral pressure remains at the level of atmospheric pressure
Production of nasals
Maintained complete closure of oral cavity
Velum lowered so air flows out through the nose
Production (laterals)
Complete closure of oral cavity
Sides of tongue down so air flows out through non-median channels
Lateral fricative
Sides of tongue in close approximation with teeth or roof of the mouth
Production (rhotics)
Airflow pushed down middle of mouth
No contact between articulators
Production (glides)
Airflow pushed down middle of mouth
Have target configuration but not held
No contact between articulators
Approximants that can be maintained
Nasals and laterals
Obstruents
Plosive & fricatives Supra-laryngeal sound source Air pressure difference Turbulent airflow Outer edges of syllables
Sonorants
Approximants & vowels Laryngeal sound source Air pressure constant Laminar airflow Occur near centre of syllables
