Plosives Flashcards
Initiation (plosive)
Pulmonic egressive ASM
Degree of structure (plosives)
Maintained complete closure
Three phases of plosives
Approach
Hold
Release
Voiced plosives
Glottis held closed by intrinsic laryngeal adductor muscles under moderate tension
Voiceless unaspirated plosives
Glottis narrowly open, held by intrinsic laryngeal adductor muscles under weak tension
Voiceless aspirated plosives
Glottis wide open held by intrinsic laryngeal abductor muscles under full tension
Devouring plosives
English word final e.g. robe
Spirantisation - turning a plosive into a fricative
No intra-oral air pressure build up behind closure
Pre-nasalise plosives
Let some air out through nose
Acoustics of approach (plosive)
Dying amplitude
Acoustics of hold (plosives)
Low amplitude
Acoustics of release (plosives)
Transient burst
Voiced plosives
There is vocal fold vibration during the hold phase
VOT
Time between a plosive burst and the onset of voicing
Aspiration
Weak frication noise following consonantal release
Associated with a long VOT
