The sounds [w] and [ʍ] in the given words are allophones of the same phoneme. They are in complementary distribution, with [w] occurring after vowels and [ʍ] occurring word-initially. The phonological rule is that the phoneme is realized as [w] in the environment of _V (after a vowel) and as [ʍ] elsewhere, specifically word-initially. As they do not contrast meaningfully in any context, [w] and [ʍ] are considered variants of the same underlying phoneme.
2. What is Phonology?
It is a field of linguistics which studies the
distribution of sounds in a language as well
as the interaction between those different
sounds.
3. What is Phonology?
Phonology tackles the following questions:
What sounds in a language are predictable?
What is the phonetic context that predicts the
occurrence of these sounds?
Which sounds affect the meaning of words?
4. Phonetics Vs Phonology
Phonetics: studies how speech sounds are
produced, their physical properties & how
they are interpreted.
Phonology: studies the organization of
speech sounds in a particular language.
5. Distinctive and Non-distinctive Sounds
Distinctive (contrastive) Sounds: make a difference in
meaning; e.g. /p/ & /b/ in pin, bin.
Non-distinctive (non-contrastive) Sounds:
Do NOT make a difference in meaning; e.g. [ph] in pin & spin.
Example:
/t/ in : top [thɒp]
stop [stɒp]
little [liɾ l]
kitten [kiʔn] (n is syllabic here)
hunter [hʌ nr]
6. Phoneme and Allophone
A phoneme: a class of speech sounds that are identified
by a native speaker as the same sound; e.g. /t/;
unpredictable (given “in” in pin like the example above
we CANNOT predict which sound can come before it like
bin, tin, din, kin, gin, fin, thin, sin, shin, chin)
A phoneme: a class of speech sounds that are identified
by a native speaker as the same sound; e.g. /t/;
phonemes are unpredictable
A phoneme is an abstract representation & cannot be
pronounced (it is not a speech sound)
A phone: the actual phonetic segment produced by a
speaker & has been classified as belonging to some
phoneme; e.g. [th]; predictable
An allophone: a variant of a phoneme, e.g. /t/ = [ʔ], [ɾ]
7. Phoneme and Allophone
The phonological system of a language has two levels:
1- the more concrete level which involves the physical
reality of phonetic segments, the allophones represented
by square brackets [ ] (greater number).
2- The abstract (underlying) level which involves phonemes
represented by / / slanted brackets (small inventory).
/p/ has 3 allophones ([p], [ph], [p̚ ])
Similar to natural sciences (H2O is realized as ice,
water, & water vapor); different realizations/forms of the
same thing.
8. Distribution of Speech Sounds
The distribution of a phone = the set of phonetic
environments in which it occurs.
Contrastive Sounds: if two sounds are separate
phonemes, they are contrastive
(interchanging the two, change the meaning of a word)
Non-contrastive Sounds: if two phones are allophones of
the same phoneme, they are non-contrastive
(interchanging the phones, doesn’t change the meaning of
a word BUT it changes the pronunciation)
9. Minimal Pair : Commutative test
A test to determine whether sounds are contrastive
or not.
Defined as a pair of words with different meanings
which are pronounced exactly the same way except
for one sound that differs: pat, bat, fat, sat, mat
Thus /p, b, f, s, m/ are separate phonemes.
In some languages, no minimal pairs, but we can
still establish phonemes
Near Minimal Pair: (differ in more than one sound
but the environment of the sound is identical short i
and schwa in ‘mission’ & ‘vision’)
10. Kinds of Phonemic Distribution
Overlapping Distribution: when the sets of phonetic environments
in which two sounds occur are partially or completely identical.
bait [bet] date [det]
lobe [lob] load [lod]
knobs [nabz] nods [nadz]
Two Kinds:
1- Contrastive distribution (give different meanings= belong to
different phonemes = appear in minimal pairs)
2- Free Variation (never cause a contrast in meaning = allophones
of the same phoneme = no minimal pairs)
mat mat maʔ can be released, unreleased or a glottal stop
either iðər aiðər – neither niðər, naiðər –
tomato təmætə, tometə - data dæta , deta
11. Kinds of Phonemic Distribution
Complementary Distribution (mutually exclusive, non-
overlapping): when sounds DON’T occur in the same
phonetic environment
English
spat [spæt] pat [phæt]
spool [spul] pool [phul]
speak [spik] peek [phik]
No minimal pairs for such sounds
Phones in Complementary Distribution are allophones of
a single phoneme
The appearance of one allophone or the other is
PREDICTABLE.
In Thai and Korean [p] and [ph ] are separate phonemes
12. Phonological Rules
Two levels of representation:
1- underlying (phonemic, mental)
2- surface (phonetic)
Why do we need rules?
- to link the two levels
- to show when a particular allophone should
show up on the surface
14. Phonological Rules
Definition
A phonological derivation is the set of stages used to
generate the phonetic representation of a word from its
underlying representation.
Discussion
Here is a diagram of the stages in a derivation.
Phonological rules influence each stage of a derivation:
Examples (English)
Here are some examples of the derivations of words
having the negative prefix /In/:
15. Phonological Rules
Phonological rules state that some item becomes
some other item in some specific environment
The common way of expressing rules:
A B/ X____ Y
A becomes B in the environment of (/) being
preceded by X and followed by Y
____ represents the position of the item affected by
the rule
( XAY) becomes (XBY)
16. Phonological Rules
Example from English:
˷ ˷
[fæn]: /æ/ /æ/ /____/n/
A vowel is nasalized whenever it immediately
precedes a nasal stop
[+ syllabic] [+nasal]/ __ [+nasal]
A +syllabic sound (= a vowel) becomes + nasal (= nasalized)
when it comes before a + nasal sound (= m, n, ŋ)
The above captures a generalization about all
vowels not only [æ] and all nasals not only [n].
17. Choosing the Underlying Form
How do we decide on the representation at the
phonemic level?
Phonemes and their allophones SHARE some
phonetic features
The choice is “phonetically natural”
Take the form which has the simplest form
18. Choosing the Underlying Form
How do we decide on the representation at the
phonemic level?
We can use an arbitrary number like 3 or Fred = harder to
read the rules
Using /p/ tells us that the allophones associated with /p/ all
share some features like [voice, continuant, anterior,
coronal].
/p/ is the simplest of the 3 phonetic forms with nothing
added to its ‘p-ness’ like being aspirated or being
unreleased: /pʰ/ and /p̚/
Use the form with the widest distribution
19. 7.13 p. 104
Form with the widest distribution:
Take the case of the devoicing of liquids and
glides following voiceless consonants
kwit, flei, trap, pjur, swaip (all are devoiced)
jɛs, wiʃ, bɔƗ, sk^ri, brik glas, fiƗθ, fiƗm
If the [–voice] allophone were chosen to
represent then our rule(s) would specify
many environments thus the rule would be:
20. “A voiceless oral sonorant (liquid or glide)
becomes voiced when:
1. word-initial
2. word-final
3. before a consonant
4. between two vowels
5. following a voiced consonant (see p. 105)
21. So using the voiced member of the pair i.e.
the allophone with the widest distribution is:
Simpler
Expresses a generalization that non-nasal
sonorants (liquids and glides) devoice following
voiceless segments
Shows there is an assimilation process with
voicelessness spreading to the following
consonant.
22. Phonetic Naturalness
& Phonological Analysis
Natural means “to be expected”, “frequently found
across languages”
Does NOT mean “English-like”
No words in English begin with onset clusters like
[ps], [pn], [pt].
These clusters appear word initially in other
languages like German, Greek, & French.
23. Phonetic Naturalness
& Phonological Analysis (cont)
What applies to one language is not necessarily true
of other languages.
English /p/ has unaspirated p and aspirated p as
allophones
Thai /p/ and /ph/ are two phonemes:
paa ‘forest’
ph aa ‘to split’
English has /p/ and /b/
Arabic has /b/ with two allophones [b] and [p]
24. Phonetic Similarity
To choose the phonemic form, we have to consider
phonetic similarity.
Example: [h] occurs syllable-initially [hæ m]
[ŋ ] occurs only syllable-finally [brɪ ŋ]
Not allophones of the same phoneme
They lack phonetic similarity
[h]: non-nasal, obstruent, continuant
[ŋ] nasal, sonorant, non-continuant
25. Pattern Congruity
Phonologists consider the consequences of choosing
one phoneme over the other
Pattern Congruity: the systematic organization of the set
of phonemes and their distribution.
Choosing an allophone depends on the overall patterns
found in the phonological system (pattern congruity)
For example:
In English: obstruent clusters have uniform voicing
Either all members of the cluster are [+ voice], or [- voice].
‘Mixed voice clusters’ DON’T occur phonemically
27. Process Naturalness
In choosing the underlying form, the linking processes
should be considered
pass [ph æs] pass you [ph æʃ ju]
this [ðɪs] this year [ðɪʃjiə ]
[s] appears in more environments so it makes sense to
choose it as the underlying form instead of vice versa
Assimilation:
[s] alveolar [+coronal, +anterior] becomes
[ʃ] palato-alveolar [+coronal, - anterior] when followed by
[j] palatal [+ coronal, - anterior]
28. Phonology
Phonology is concerned with the organization
of the system underlying the speech sounds
The phonemic level represents native
speakers’ knowledge of the sound system of
their language
29. Phonology vs. Phonetics
Phonology: is a cognitive study which deals
with the representation of knowledge in the
mind
Phonetics: deals with the physical properties
of speech sounds
