Allophonic Variation Of Manner: Allophonic Variation Of Plosives Flashcards
How many stages are there of plosive production?
Three
Allophonic variation of plosives
Nasal and lateral approach
Nasal and lateral release
No release/inaudible release
In hand, n has
Tongue against alveolar ridge, lateral contact, complete closure of airflow, velum lowered
In hand, d has
Tongue against alveolar ridge, lateral contact, complete closure of airflow, velum raised
Phase 1: nasal approach
N vs d
Articulators already together-only velum moves. Moving from nasal airstream to oral airstream
Homorganic means
Same place of articulation
Nasal approach is found
In all languages when nasal followed by stop (and homorganic)
Nasal approach: Lateral approach is identified by
Raising sides of tongue as alveolar articulation is already there
E.g cold and hold
Nasal approach :In cold, l has
Tongue against alveolar ridge, velum closed, complete closure of airflow, tongue sides lowered
Nasal approach: In cold, d has
Tongue against alveolar ridge, velum closed, complete closure of airflow, velum raised
Phase 1: lateral approach l vs d
Articulators already together only sides of tongue move
Involves changing shape of tongue from lateral to flat
Cold hold
Phase 3: nasal release b vs m
Articulators stay together-only velum moves
Phase 3 nasal release involves
Moving from oral airstream to nasal airstream
Topmost nasalisation of p
Sidney nasalisation of d
Submarine nasalisation of b
In phase 3 nasal release, homorganic describes
Plosive followed by nasal
In phase 3 nasal release: the release phase can also be moved from
The oral cavity to the nasal cavity e.g submarine
In phase 3 nasal release:
The articulators stay in place for the closure but velum is lowered so release is made through nasal cavity. Very common in English
Nasal plosion in English always occurs
With the plosive ending one syllable and the nasal beginning the next, whether within the word or at word boundaries
Nasal plosion occurs when a stop is immediately followed by a homorganic nasal
E.g Sydney, that night, it also happens with a following syllabic n e.g suddenly and eaten
Most speakers use nasal plosion before a syllabic n
But some don’t (though would use nasal plosion in other places)
Nasal plosion doesn’t happen in a
Consonant cluster (in the same syllable)
Phase 3lateral release is
Homorganic
Phase 3 lateral release: d vs l
Artoculators stay together only sides of tongue move- changing shape of tongue from flat to lateral
E.g at last t is lateralised some with d in badly
Lateral plosion is found when
A plosive is followed by a homorganic lateral
In English
Lateral plosion of t and d is common
