Assimilation and elision Flashcards
What is assimilation
Assimilation is a connected speech phenomenon that enhances the ease of articulation.
When phonemes is used in speech, it will often be colored by neighboring phonemes
Degree of assimilation
Complete assimilation
two phonemes become identical
one minute /wʌn mɪnɪt/ /wʌm mɪnɪt/
Partial assimilation
most phonemes in succession do not become identical but more similar.
How do you write a full assimilation example
The alveolar plosive /t/ has changed to bilabial /p/ before bilabial /b/. This is a partial regressive assimilation of place of articulation.
Direction of assimilation
Progressive = right to left
Regressive = left to right
Place of articulation
assimulation most often involves a change in a place of articulation..
Rule A:
Rule a: an alveolar place of articulation changes to bilabial when it is followed immediately by a bilabial place of articulation
/t/ changes to /p/ before /p,b,m/
/d/ changes to /b/ before /p,b,m/
/n/ changes to /m/ before /p,b,m/
Rule B
An alveolar place of articulation changes to velar when it is followed immediately by a velar place of articulation
/t/ changes to /k/ before /k,g/
/d/ changes to /g/ before /k,g/
/n/ changes to /ŋ/ before /k,g/
Rule C
The alveolar fricatives /s/ and /z/ assimilate phonemically in only one direction, to / ʃ/ and / ʒ/, a retraction of the lamina from alveolar to postalveolar
Rule c:
/s/ changes to / ʃ/ before /ʃ, j/
/z/ changes to / ʒ/ before /ʃ, j/
Force of articulation
also called fortis/lenis variation
word-final lenis consonant becoming fortis before a word initial fortis-consent.
mainly /v,z,d/ before /t/
hæv tu - hæf tu
manner of articulation
not common.
changing from an oral to a nasal consonant
Elision
Elision is when you drop a phoneme to get a more fluent speak pattern.
next bus /nekst bʌs/ –> /neks bʌs/
Elision of vowels
Elision of consonants
