Fricative And Affricates Flashcards
Initiation of fricatives
Pulmonic, egressive ASM
Fricatives degree of stricture
Maintained close approximation
Phases of fricative production
Approach
Hold (continuous airflow)
Ejective fricatives
Exist in the form of floral pic egressive
Voiced fricatives
Glottis held closed by intrinsic laryngeal adductor muscles under moderate tension
Voiceless fricatives
Glottis held open by intrinsic largest abductor muscles under full tension
Median fricatives
Air flows along midline of tongue
Lateral fricatives
Air flows along sides of tongue
Fricative channel shape
Either a slit or a groove (louder)
Grooves produce sibilants
Sibilants
Louder/higher amplitude as noise comes from both close approximation and hitting an obstruction
Phases of affricate production
Approach
Hold
Release
Hold
Aggravates are homorganic
Complete closure and close approximation are at same place if articulation
