Phonology
The sound patterns of language
What is Phonology?
Peter
what is Phonology?
the study about how speech sounds form
pattern is Phonology.
the linguistic knowledge that speakers have
about the sound patterns of their language.
the description of that knowledge that
linguists try to produce.
Phonology tell us...
sounds in our language v.s. foreign language.
impossible combination of sounds *Mbick.
certain phonetic features can identify a word.
adjust our pronunciation and morphemes
the pronunciation
of morphemes
how we pronounce words and parts of words
we call morpheme.
certain morphemes are pronounced
differently depending on their contexts.
for example...
the pronunciation
of Plurals
cat/cats, dog/dogs, house/houses, ox/oxen
what’s the difference of their plural forms
pronunciation?
How do we know how to pronounce these
plural nouns ?
The final sound of
the plural nouns
column A is a [z], a voiced alveolar fricative
column B is a [s], a voiceless alveolar
fricative
column C is a [əz]
column D are a hodge-podge of special cases.
What is allomorph ?
the more technical term for variant of a
morpheme.
phonological analysis

there are some property of the environment
associated with each group of allomorph.
[kæb] or [lʌv] / [bʌs] or [bʌz]

identical except for one sound segment
that occurs in the same place in each word.

bus [bʌs] / buzz [bʌz] , final segment
the distribution of
plural allomorphs
conditioned by the final segment of the
singular form.
inspection
[əz] : after sibilants segment
[s] : after voiceless nonsibilant segment
[z] : after voiced nonsibilant segment
Rules - phonetic forms
of all plurals
we assume that the basic or underlying form
of the plural morpheme is /z/, with the
meaning ‘plural.’ This is the “default”
pronunciation.
Rules - phonetic forms
of all plurals
if no rule applies, then the plural morpheme will be
realized as [z]
conclusion
The particular phonological rules that
determine the phonetic form of the plural
morpheme and other morphemes of the
language are morphophonemic rules.
Such rules concern the pronunciation of
specific morphemes.
conclusion
That the rules of phonology are based on
properties of segments rather than on
individual words is one of the factors .
Once the rule is learned, thousands of word
forms are automatically known.
conclusion
English is not the only language that has
morphemes that are pronounced differently
in different phonological environments.
Many languages have morpheme variation
that can be described by rules similar to the
ones we have written for English.
Phonemes and Allophone
Cheng Yu (Feather)
what is a Phoneme?
The phonological unit of languge
You use phoneme to build words
Abstract basic form of a sound as sensed
mentally rather than spoken or heard
Manifested physically by one or more actual
sounds, called “allophone”
what are Allophones ?
the perceptible sounds corresponding to the
phoneme in various environment
the sounds we can actually feel and sense
physically, depending on the phoneme in
different environment
Example
The phoneme [p]
aspirated allophone [pʰ]: pit
without aspirated allophone[p]: spit
Example
Nasality
Vowels are nasalized before a nasal consonant within the same syllable
how to find Phoneme
Minimal pair
substituting one sound for another
in a word to see if it makes a difference
how to find Phoneme
[i] [ɪ] [e] [ɛ] [æ] [u] [ʊ] [ɑ] [o] [ɔ] [ɑ] [ʌ] [aɪ] [aʊ] [ɔɪ]
each vowel phoneme have at least 2
allophones, which means they have two
ways of being pronounced. ex. orally or
nasally.
the choice of the allophone is not random
but rule-governed
What is a Phone?
a particular realization (pronuncation) of a
phoneme
the aggregate of phones that are the
realization of the same phoneme are called
the allophones of that phoneme
phonemic transcription
slashes // are for phonemes
brackets [ ] are for allphones or phones
Complementary Distribution
Where A occur, B do not occur, vise versa.
Ex. Where oral vowels occur, nasal vowels do not occur, vise versa.
In this sense, the phones are said to complement each other——to
be in complementary distribution.
Complementary Distribution
Contrastive:
can be used to make different words
ex. big/dig
Non-contrastive:
cannot be used to make different words
ex. letter(tʰ/ɾ)
Complementary Distribution
Contrastive sounds constitute the phonemes of the
language
“the allophones of a phoneme”do not contrast
with each other, and are in a complementary
distribution---never occurring in identical
environments
the Need for Smilarity
When sounds are in complementary distribution, the
replacement of one sound for another will not change
the meaning of the word
→A phoneme can be viewed as a set of phonetically
similar sounds that are in complementary distribution
the choice of one or another allophone (pronunciation)
is determined by its phonetic environment
the Need for Smilarity
Complementary distribution alone is not sufficient to
determine the allophones of a phoneme, the phones must be
phonetically similar
Ex. velar nasal[ŋ] and glottal fricative [h] are in
complementary distribution, but [ŋ] does not occur wordinitially and [h] does not occur word-finally. Other than that,
they also share very few phonetic features: [ŋ]is a voiced velar
nasal stop; [h] is a voiceless glottal fricative. Therefore, they
are allophones of different phonemes.
(sort of a)conclusion
Speakers of a language generally percieve the
different allophones of a single phoneme as the
same sound or phone. For example, bead/bean,
because mentally, speakers produce and hear
phonemes, not phone.

Distinctive Features of Phonemes
Phonetics
Phonology
1.provides the means to describe the
phones (sounds) of language
tells us how various sounds form
patterns to create phonemes and their
allophones
2.showing how they are produced and
vary
Distinctive Features of Phonemes
[s] & [z] represent two contrasting
phonemes in English
seal [sil] & zeal[zil]
allophone of one phoneme
because one cannot replace the [s] with the [z]
without changing the meaning of the word
Distinctive Features of Phonemes
seal [sil] & zeal[zil]
> The fact that you can find a minimal pair also means
they are not in complementary distribution as both
occur word initially before the vowel [i]
> They are therefore allophones of the two different
phonemes /s/ and /z/
Distinctive Features of Phonemes
seal [sil] & zeal[zil]

feel & veal: [f] / [v]

Distinctive Features of Phonemes
when a feature distinguishes one phoneme from
another, hence one word from another,
it is a distinctive feature or a phonemic feature
Feature Value
Sharon
Feature Values
one can think of voicing and voicelessness as the
presence or absence of a single feature, voiced.
plus(+): presence , minus(-): absence
ex: [b]:[+voiced], [p]:[-voiced]
Feature Values
The presence or absence of nasality can
similarly be designated as [+nasal] or [-nasal]
plus(+): presence , minus(-): absence
ex: [m]:[+nasal][b]:[+nasal], [p]:[-nasal]
Feature Values
We consider the phonetic and phonemic symbols to
be cover symbols for sets of distinctive features
They are a shorthand method of specifying the
phonetic properties of segments.

Nondistinctive Features
Sharon
Nondistinctive Features
distinctive feature of English consonants
Aspiration
nondistinctive/redundant/predictable
feature
some features may be distinctive for one class of sounds
but predictable for another
(means predictable by rule)
Nondistinctive Features
ex: nasality is a distinctive feature of English consonants
but not for English vowels
predict when an /m/ or an /n/ will occur in an English word
predict the nasality feature value of the vowels in bean,
mean, comb, and sing
(because the nasalized vowels occur before nasal consonants)
the feature nasal is nondistinctive for vowels
Nondistinctive Features
Nasality on vowels is phonemic in Portuguese
Nasalization is a distinctive feature for vowels in Akan
[ka] “bite”
[fi]
“come from”
[tu] “pull”
[nsa] “hand”
[tʃi] “hate”
[pam]“sew”
[kã] “speak”
[f ĩ]
“dirty”
[tũ] “den”
[nsã] “liquor”
[tʃ ĩ] “squeeze”
[pãm] “confederate”
Nondistinctive Features
Another nondistinctive feature in English is aspiration for
voiceless stops.
The voiceless aspirated stops [pʰ],[tʰ] and [kʰ] and the voiceless
unaspirated stops [p], [t], and [k] are in complementary
distribution.
Phonemic Patterns May
Vary across Languages
Sharon
Aspiration is a phonetic feature in Thai just as in English,
but it functions differently in the two languages.
Voiceless Unaspirated
Voiceless Aspirated
[paa] forest
[tam] to pound
[kat] to bite
[pʰaa]to split
[tʰam] to do
[kʰat] to interrupt
In English they are allophones of the phonemes /p/, /t/, and /k/;
in Thai they represent the distinct phonemes /p/, /t/, /k/,/pʰ/,
/tʰ/, and /kʰ/.
aspiration is a distinctive feature in Thai;
it is a nondistinctive redundant feature in English
The phonetic facts alone do not reveal
what is distinctive or phonemic:
The phonetic representation of utterances shows what speakers
know about the pronunciation of sounds.
The phonemic representation of utterances shows what speakers
know about the patterning of sounds.

In ASL phonology, signs can be decomposed into
handshape, movement, and location.
“candy”,”apple”,”jealous”:
articulated at the same location on the face
involve the same movement
but contrast minimally in hand configuration
“summer”,”ugly”,”dry”:
a minimal set contrasting only in place of articulation
“tape”,”chair”,”train”:
contrast only in movement
Like sounds, signs can be decomposed into
smaller minimal units that contrast meaning.
Some features are non-distinctive.
Whether a sign is articulated on the right or left hand
does not affect its meaning.
Natural classes of
speech sound
Ryan
Natural classes of speech sound
Phonological rules determine vowels-- nasalized,
voiceless stop aspirated.
Apply to made- up words
Sint, peeg, sparg
phonemically
/sɪnt/, /pig/, /sparg/
phonetically.
[sĩnt], [phig], [sparg]
Similar phonological rules involve the same classes of
sounds such as nasal and voiceless stop.
Nasalized vowel before nasal consonant.
[ +nasal ]
[ +voiced ], [ -voiced ]
Ex. Aspirated sounds [ -voiced ]
Voiceless
Natural classes
A group of sounds described by a small number of
distinctive features.
[–voiced], [–continuant]
[–voiced], [–continuant]
/p/, /t/, /k/, /ʧ/.
However...
/p/
[–voiced], [–continuant], [+labial].
Feature-Changing
Rules
Danny
rules change features from one value to its opposite or
even add features not present
rule in English aspirates voiceless stops at the
beginning of a syllable
rule : aspirates voiceless stops at the beginning of a
syllable
/p/
/p/
pit , repeat
inspect , compass
aspirated [pʰ]
unaspirated [p]
We can now state the rule
A voiceless noncontinuant has [+aspirated] added
to its feature matrix at the beginning of a syllable
when followed by a stressed vowel with an optional
intervening consonant.
Assimilation Rules
The vowel nasalization rule is an assimilation rule that
makes neighboring segments more similar by adding the
feature [ +nasal] to the vowel.
the vowel nasalization rule
Vowels are nasalized before a nasal consonant within the
same syllable.
This rule specifies the class of sounds affected by the rule:
Vowels
It states what phonetic change will occur by applying the rule:
Change phonemic oral vowels to phonetic nasal vowels.
and it specifies the context or phonological environment.

Segment Insertion
and Deletion Rules
Alesa
Phonoligical rules may add or delete entire segment.
Epenthesis
The process of inserting a consonant or vowel.
The rules for forming regular plurals, possessive forms,
and third-person singular verb agreement in English all
require an epenthesis rule.
Example
●insert a /ə/ before morpheme /z/ ➝[əz]
eg. kiss➝kisses
●add a [z] to squeeze to form its plural➝[skwizː]
But it would be hard for English speakers to distinguish from [skwiz],
because they do not contrast long and short consonants.
Segment deletion
One such rule occurs in casual or rapid speech.
Example
mystery➝mystry general➝genral memory➝memry
funeral➝funral
vigorous➝vigrous Barbara➝Barbra
Segment deletion
The silent g that torments spellers in such words.

Prosodic Phonology
Melody
Syllable Structure
one or more phonemes
a phonological unit
one or more syllables
words
Every syllable has a nucleus
usually a vowel
(but can be a syllabic liquid or nasal)
may be preceded and/or followed
by one or more phonemes called the
syllable onset and coda.
Syllable Structure
Jack and Jill
Went up the hill
To fetch a pail of water.
Jack fell down
And broke his crown
And Jill came tumbling after.
In rhyming words, the nucleus and the coda of
the final syllable of both words are identical.
the nucleus + coda constitute the subsyllabic
unit called a rime (note the spelling).
Using the IPA symbol σ for the phonological
syllable, the hierarchical structure of the
monosyllabic word splints can be shown:
Word Stress
one or more of the syllables in every content word are stressed
Be marked by an acute accent (')
Example:
pérvert (noun) as in "My neighbor is a pervert."
pervért (verb) as in "Don't pervert the idea."
súbject (noun) as in "Let's change the subject."
subiéct (verb) as in "He'll subject us to criticism.
adjective inválid (not valid) /the noun invalid (a sickly person).
Word Stress
The vowel that receives primary stress is marked by an acute
accent (´). The other stressed vowels are indicated by grave
accents (`) over the vowels
Example:
rèsignátion lìnguístics
sỳstemátic
fûndaméntal ìntrodúctory rèvolútion
vowels in unstressed syllables are pronounced as schwa [ǝ]in
English except at the ends of certain words such as confetti,
laboratory, and motto.

prosodic or suprasegmental feature.
Sentence and Phrase Stress
Is capable by varied vocal inflexions of expressing all
states of mind.
only one of the vowels in a phrase (or sentence)
receives primary stress or accent.
we place primary stress on the adjectival part of a
compound noun (which may be written as one word,
two words separated by a hyphen, or two separate
words)=>chapter3
Sentence and Phrase Stress
we place the stress on the noun when the words are a
noun phrase consisting of an adjective followed by a
noun.
Example:
Sentence and Phrase Stress
1. stress may be predictable from the morphology and
syntax.
2. The stress differences between the noun and verb pairs
are also predictable from the syntactic word category.
Intonation
Pitch still plays an important role, but only in the form of the
pitch contour or intonation of the phrase or sentence.
=>is also a phonemic feature in tone languages such as
Chinese, Thai, and Akan.
Intonation may reflect syntactic or
semantic difference.

Sequential Constraints
of Phonemes
Patrick
Phonotactic Constraints
Limitations on sequences of phonemes that exist
in all languages, albeit with different constraints.
What makes “explicit” a possible English
word but not “condstluct”?
Explanation:
Syllables are the basis of phonotactic constraints, so only
clusters that can begin a syllable can begin a word and only a
cluster that can end a syllable can end a word.
The former does NOT violate any rules because of a clear
syllable boundary between /k/ and /spl/
The latter does violate this rule because the second syllable
starts with the impermissible onset of /stl/ or /tl/
Accidental gaps

Why Do Phonological Rules Exist?
page 258
“Many linguists believe that
phonological rules exist to ensure that
the surface or phonetic forms of words
do not violate phonotactic constraints. If
underlying forms remained unmodified,
they would often violate the
phonotactics of the language.”
page 259
“Thus phonological rules exist because
languages have general principles that
constrain possible sequences of sounds. The
rules specify minimal modifications of the
underlying forms that bring them in line with
the surface constraints. Therefore, we find
different variants of a particular underlying
form depending on the phonological context.”
Constraints in
different languages
Twi, a language
spoken in Ghana
/pik/ is not a possible word in
Twi but /mba/ is because
words in Twi may end only in
a vowel or nasal consonant
(e.g. /mba/, /bam/, /ban/)
Constraints in
different languages
Polish language
/zl/ and /kt/ - which are
impermissible in English - are
permissible syllable-initial
combinations in Polish
Constraints in
different languages
Croatian language
/ml/ in Mladen - which is
impermissible in English - is a
permissible sequence in
Croatian
Constraints in
different languages
Japanese language
Severe constraints In
Japanese on what may begin
a syllable means very few
combinations are permissible
(usually a consonant and a
vowel with /sh/ being one
exception)
English
Obstruent sequences may not
differ with respect to their voice
feature at the end of a word (e.g.
[kasb], [kabs] VS [kasp], [kɛbz])
Consonants
cannot be
followed by
another stop
consonant (e.g.
*bkli)
If a word begins
with an /l/ or an
/r/, the next
segment MUST be
a vowel (e.g. lamp,
road)
Sequences of obstruents that
differ at most with respect to
voicing are not permitted
within English words
(Constraint A)
Optimality Theory
This theory proposes that a universal set of phonological constraints exists. This
set is ordered and some constraints are more highly ranked than others. The
higher the constraint is ranked, the more influence it exerts on the language.
As we’ve seen through the past-tense rule, English highly ranks constraint A
In Modern Hebrew, constraint A is highly ranked, so suffixes that begin with
/t/ are always separated from stems ending in /t/ or /d/ by inserting [e] as
in /kiʃat + ti/ ([kiʃatetɪ])
In Berber, constraint A is NOT highly ranked, so /tt/, /dd/, and /ss/
consonants can surface
