Phonology:  Sound Patterns

 

Discreteness:

·      Variation in speech heard as discrete sounds

 

lay [le]

play [pl8e]

ray [re]

pray [pr8e]

wine [wayn]

twine [tw8ayn]

 

sew [so]

sewn [so)n]

lap [lQp]

lamp [lQ)mp]

tog [tag]

tong [ta)N]

 

tar [tHar]

star [star]

pa [pHa]

spa [spa]

car [kHar]

scar [skar]

 

·      The discrete or distinctive sounds are called phonemes and we use / / to represent them.

 

·      The variations of phonemes are called allophones and we use [] to represent them.


We can describe allophonic variation with the use of features (voicing, place, manner) to make generalizations.

 

/l/

/r/

/w/

 

[]       [l]

[r8]       [r]

[w8]       [w]

 

·      Generalization: Approximants are devoiced when they follow voiceless sounds.

 

 

/o/

/Q/

/a/

[o]       [o)]

[Q]       [Q)]

[a]       [a)]

 

·      Generalization: vowels are nasalized when they precede nasal sounds.

 

 

/t/

/p/

/k/

[t]       [tH]

[p]       [pH]

[k]       [kH]

 

·      Generalization: voiceless stops are deaspirated when they follow [s].


How do we know if two sounds are separate phonemes or are allophones of the same phoneme?

 

Minimal Pair Test

 

·      [p] and [t] are separate phonemes because we can find minimal pairs.  They are able to create a difference in meaning by substituting one for another.

 

 [pIn]

[tIn]

[rayp]

[rayt]

[spok]

[stok]

 

·      [p] and [pH] are not separate phonemes because we cannot find minimal pairs. They cannot create a meaning difference when one is substituted for another.

 

o    [pH] occurs at the beginning of a word

o    [p] occurs after [s]

 

·      What about [p] and [b]?

 

·      What about [Q] and [Q)]?

 

·      What about [r] and [l]?


What about these Hindi words?

 

[tal]       ‘applause’

[thal]      ‘plate’

 

[kaj&]       ‘particle’

[khaj&]     ‘itch’

 

 

Native language allophones è Second language phonemes

 

English [k] and [kh] è Hindi /k/ and /kh/

 

Spanish [e] and [E] è English /e/ and /E/

 

 

 

 


What causes allophonic variation?

 

Co-articulation effects are a common cause.

 

·      Assimilation: a sound becomes more similar to a neighboring sound

 

o    Vowel Nasalization

o    Approximant Devoicing

o    Place Assimilation

I can try [ayk«ntray]

I can go [ayk«Ngo]

I can be [ayk«mbi]

 

·      Elision: Deletion of a consonant in clusters

 

o     [t] is often deleted when part of a syllable final cluster

aspects [QspEks]

trust me [tr«smi]

we asked him [wiaskIm] or [wiastIm]
