Phonology
not all sounds can go together in a word
some phonetic details are predictable, given the environment
Contrast: and
For instance, shore and sore mean different things. They are a minimal pair.
English Minimal Pairs
Japanese English“do” “cut viciously with knife”
! acceptable in words like see
Both languages have both sounds
predictable before [i]
not predictable
Predictable
before voiced consonant
before unvoiced consonant
Predictable
Complementary distribution
before unvoiced
consonantno yes
before voiced consonant yes no
Complementary distribution
Two sounds X and Y are in complementary distribution if Y never occurs in any of the phonetic environments in which X occurs.
i.e. a minimal pair could never be exhibited
English non-contrasts
Hindi contrasts
“fruit”“moment”“strength
•two sounds are in contrast•a minimal pair can be found
(they can occur in the same contexts) •the sounds belong to different phonemes
•two sounds are psychologically nondistinct•no minimal pair can be found
(forced by complementary distribution)•they are allophones of the same phoneme
What about and ?
The flap in English vs. Spanish
Predictably, /t/ surfaces as in English[ ]Flapping:
in environments where it is surrounded by vowels, the 2nd of which is stressless
in Spanish, the flap is contrastive
[pita] “century plant”“funeral pyre”
Nasality
‘luxurious’‘stalk’‘scold’‘ascend’‘forbid’‘eat’‘house’‘car’
Malay
‘but’ ‘hand’‘very’ ‘train’
French
Example problem
Formalizing vowel shortening
“in the environment”
[e] !" / [voiceless consonant]
Formalizing vowel shortening
“in the environment”
“is realized as”
[e] !" / [voiceless consonant]
Formalizing vowel shortening
“in the environment”
“is realized as”“before”
[e] !" / [voiceless consonant]
Formalizing vowel shortening
happens with other Vs too, e.g.coat/codelap/lab
“in the environment”
“is realized as”“before”
[e] !" / [voiceless consonant]

The TheoryPostulate two levels
1. underlying form (string of phonemes that are distinctive in this language)
2. surface or phonetic form (specifying particular phones in a language-independent way)
and provide phonological rules that derive the surface form from the underlying form.The rule format we will use is A ! B/ C D “A rewritten as B in the context where it ispreceeded by C and followed by D.”
Any of A,B,C,D might be written more generally as a feature matrix
!
"#+ feature" feature

%&
A feature matrix makes positive or negative reference to a combination of phonologicalfeatures like nasal, voiced, high, a!ricate etc. Such combinations specify natural classes.
English voicing data indicates that /r/ patterns with /l/.

so do /j/ and /w/
