Phonetics is the study of how speech sounds are produced, transmitted and perceived
2 Main branches of phonetics
2.1 Articulatory phonetics
Articulatory phonetics deals with the way in which the speech sounds are produced It describes speech sounds genetically - that is, with respect to the ways by which the organs of speech modify the air stream in the throat, the mouth, and the nose in order to produce a sound The production of different speech sounds through the use of the organs
of speech is known as articulation
2.2 Acoustic phonetics
Acoustic phonetics deals with the transmission of speech sounds through the air It is the study of speech waves as the output of a resonator A spectrograph may be used to record significant characteristics of speech waves and to determine the effect of articulatory activities Parts of this record of speech waves can be cut out experimentally and the rest can be played back as sound in order to determine wich features suffice to identify the sounds of a language
2.3 Auditory phonetics
Auditory phonetics deals with how speech sounds are perceived by the listeners The auditory aspect of speech is very important: the ear is capable of making fine discrimination between different sounds, and sometimes it is not possible to define in articulatory terms precisely what the difference is
II Phonetics and Phonology
Trang 54
As seen above, phonetics is the study of pronunciation, that is, the study of human speech sounds Besides having the physical properties, the speech sounds aso have the distinctive function when they are used as distinctive units of sounds in a language According to I J Ohala (in R.E Asher, 1994: 3053), othe designations for this field of inquiry include
“speech science” or “the phonetic sciences” and “phonology” Some apply the term
“phonetics” to the physical, including physiological, aspects of speech; others prefer to reserve the term “phonology” for the study of the more abstract, the more functional, or
the more psychological aspects of the underpinnings of speech
Phonetics, as used in this course of study, is the study of all speech sounds and the ways
in which they are produced The main aims of phonetics are to describe human speech sounds
Phonology is the study and identification of the distinctive unit of sound in a language The most basic activity in phonology is phonemic analysis, in which the objective is to establish what the phonemes are and arrive at the phonemic inventory of the language Very few phonologists have ever believed that this would be an adequate analysis of the sound system of a language: it is necessary to go beyond this One can look at suprasegmental phonology - the study of stress, rhythm and intonation, which has led in recent years to new approaches to phonology such as metrical and autosegmental theory; one can go beyond the phoneme and look into the detailed characteristics of each unit in terms of distinctive features; the way in which sounds can combine in a language is studied in phonotactics and in the analysis of syllable structure For some phonologists the most important area is the relationships between the different phonemes - how they form groups, the nature of the oppositions between them and how those oppositions may be neutralised

UNIT 2: THE ORGANS OF SPEECH
Vocal tracts and articulators
Names of articulators
Perhaps readers and learners may get confused with the terms used for the articulators The table below will help to make clear the common names and what each of them mean Normal name Fancy name Adjective Normal name Fancy name Adjective
(soft) palate Velum Velar Tongue body Dorsum
(back)
Dorsal
Trang 87
lungs A few languages use the epiglottis in making sounds English is fortunately not one
of them
Vocal folds/vocal cords
folds of tissue stretched across the airway to the lungs They can vibrate against each other, providing much of the sound during speech
Oral cavity
the part of the mouth behind the teeth and gums that is bounded above by the hard and soft palates and below by the tongue and the mucous membrane connecting it with the inner part of the mandible
Nasal cavity
the cavity on either side of the nasal septum, extending from the nose to the pharynx, and lying between the floor of the cranium and the roof of the mouth
Trang 10Tongue Backness
The second aspect of vowel classification that you will be introduced to is that of tongue backness Vowels are classified in terms of how far the raised body of the tongue
is from the back of the mouth, which is called the backness of the tongue
There are three primary height distinctions among vowels: front, back, and central
In English, examples of front vowels are /w/, /i:/, /e/, /æ/ These vowels are articulated relatively forward in the mouth Examples of back vowels are /•/, /u:/, /Y:/, /Z/, /]:/ These vowels are articulated relatively far back in the mouth Examples of central vowels are /∂/, /f:/, /ž / These are vowels whose tongue positions are roughly between the front and back vowels
These classifications, like the tongue heights, are quite relative, as different languages have different canonical tongue backnesses for different classifications
As illustration of tongue backness, observe the following diagrams for the vowels /w/, /u:/
Trang 11Vowel Length
Vowel length is the length of time it takes to pronounce the vowel We can measure this length in centiseconds - hundredths of a second
Short English vowels: /w/, //, /æ/, /Z/, /e/, /∂/, //
Long English vowels: /i:/, /u:/, /Y:/, /]:/, /f:/
Some languages, like English, vary the lengths of their vowels according to certain rules Below you can see the typical or average length of some of the vowels in English
As we will see, there is not a clear-cut long/short distinction Typically, each vowel has its own length, with for instance /æ/ holding a half-way position between lax and tense vowels Also, lengths of different vowels overlap in different contexts: looking at /i:/ and /w/ we found the following situation The lengths are given in centiseconds
Tense vs Lax
Another aspect of vowel classification is commonly characterized in terms of the tenseness or laxness of the articulators Some vowels, such as the vowels /i:/ and /e/, are formed with a high degree of tenseness Such vowels are called tense vowels Some vowels, such as /∂/ and /ž /, are formed without a high degree of tenseness, and are called lax vowels
The general rule is:
lax vowels (/w/, //, /æ/, /Z/, /e/, /∂/, //) are short
tense (/i:/, /u:/, /Y:/, /]:/, /f:/) vowels (including diphthongs: /ew/, /aw/, /]w/,
/∂/,/a/, /w∂/, /∂/, /ε ∂/) are variable in length, and often longer than lax vowels

English Diphthongs
Classification of diphthongs
Diphthongs are described as sequences of two vowels pronounced together, the two vocalic elements being members of the same syllable The most important feature of a diphthong is that it contains a glide from one vowel quality to another one According to the position of the more prominent element in the diphthong we can divide diphthongs into falling diphthongs – if the prominent element comes first – and rising diphthongs – if the less prominent element comes first All English diphthongs belong to the first category Diphthongs can then be opening if the degree of aperture increases with the glide or closing if the less prominent vowel is closer than the first We can also differentiate between wide diphthongs – those in which the glide implies a more radical movement of the speech organs and narrow diphthongs – if the two vocalic elements occupy neighbouring positions on the vowel chart There are also centring diphthongs – if the glide is from a marginal vowel in the vowel chart – either back or front - to a central vowel To make it simple, we can say that there are three diphthongs ending in /w/ (/ew/, /aw/, /]w/), two ending in /∂/ (/w∂/, /∂/, /ε∂/) and three ending in // (/∂/, /a/)

The easiest way to remember them is in terms of three groups divided as in this diagram:

UNIT 4: ENGLISH CONSONANTS
Producing a consonant involves making the vocal tract narrower at some location than
it usually is We call this narrowing a constriction Which consonant you're pronouncing depends on where in the vocal tract the constriction is and how narrow it is It also depends on a few other things, such as whether the vocal folds are vibrating and whether air is flowing through the nose
We classify consonants along three major dimensions:
place of articulation
manner of articulation
voicing
For example, for the sound d:
Place of articulation = alveolar (The narrowing of the vocal tract involves the tongue tip and the alveolar ridge.)
Manner of articulation = oral stop (The narrowing is complete the tongue is completely blocking off airflow through the mouth There is also no airflow through the nose.)
Voicing = voiced (The vocal folds are vibrating.)
Places of articulation
The place of articulation (or POA) of a consonant specifies where in the vocal tract the narrowing occurs From front to back, the POAs that English uses are:
Bilabial
In a bilabial consonant, the lower and upper lips approach or touch each other English
p, b, and m are bilabial stops
The diagram to the right shows the state of the vocal tract during a typical p or b (An
m would look the same, but with the velum lowered to let out through the nasal passages.)
The sound w involves two constrictions of the vocal tract made simultaneously One of
them is lip rounding, which you can think of as a bilabial approximant
Labiodental
Trang 2019
In a labiodental consonant, the lower lip approaches or touches the upper teeth English f and v are bilabial fricatives The diagram to the right shows the state of the vocal tract during a typical f or v
Dental
In a dental consonant, the tip or blade of the tongue approaches or touches the upper
teeth English θ and ð are dental fricatives There are actually a couple of different ways
of forming these sounds:
The tongue tip can approach the back of the upper teeth, but not press against them
so hard that the airflow is completely blocked
The blade of the tongue can touch the bottom of the upper teeth, with the tongue tip protruding between the teeth still leaving enough space for a turbulent air-
stream to escape This kind of θ and ð is often called interdental
The diagram to the right shows a typical interdental θ or ð
The diagram to the right shows the state of the vocal tract during plosive t or d
The diagram to the right shows the state of the vocal tract during the first half (the stop
half) of an affricate t∫or dʒ
Retroflex
Trang 2120
In a retroflex consonant, the tongue tip is curled backward in the mouth English ɹ is a retroflex approximant the tongue tip is curled up toward the postalveolar region (the area immediately behind the alveolar ridge)
The diagram to the right shows a typical English retroflex ɹ
Both the sounds we've called "postalveolar" and the sounds we've called "retroflex" involve the region behind the alveolar ridge In fact, at least for English, you can think of retroflexes as being a sub-type of postalveolars, specifically, the type of postalveolars that you make by curling your tongue tip backward
Palatal
In a palatal consonant, the body of the tongue approaches or touches the hard palate
English j is a palatal approximant the tongue body approaches the hard palate, but
closely enough to create turbulence in the air-stream
Velar
In a velar consonant, the body of the tongue approaches or touches the soft palate, or
velum English k, g, and ŋ are stops made at this POA
The diagram to the right shows a typical k or g though where exactly on the velum
the tongue body hits will vary a lot depending on the surrounding vowels
As we have seen, one of the two constrictions that form a w is a bilabial approximant
The other is a velar approximant: the tongue body approaches the soft palate
Glottal
The glottis is the opening between the vocal folds In an /h/, this opening is narrow
enough to create some turbulence in the air-stream flowing past the vocal folds For this
reason, /h/ is often classified as a glottal fricative
Manners of articulation
Trang 2221
The manner of articulation dimension is essentially everything else: how narrow the constriction is, whether air is flowing through the nose, and whether the tongue is dropped down on one side
Stops
Stops are consonants formed by completely stopping the flow of air somewhere in the vocal apparatus, and then releasing the air Since the sudden release of the pent-up air creates a small explosive sound, stops are also called plosives Stops may be voiced (vocal cords vibrating during the articulation of the stop) or voiceless (vocal cords not
vibrating during the articulation of the stop) Here is a list of the stops in English t, d, k,
g, p and b
Fricatives
In the stop t, the tongue tip touches the alveolar ridge and cuts off the airflow In s, the
tongue tip approaches the alveolar ridge but doesn't quite touch it There is still enough of
an opening for airflow to continue, but the opening is narrow enough that it causes the
escaping air to become turbulent (hence the hissing sound of the s) In a fricative
consonant, the articulators involved in the constriction approach get close enough to each
other to create a turbulent air-stream The fricatives of English are f, v, θ, ð, s, z, ∫ and ʒ
Approximants
In an approximant, the articulators involved in the constriction are further apart still than they are for a fricative The articulators are still closer to each other than when the vocal tract is in its neutral position, but they are not even close enough to cause the air
passing between them to become turbulent The approximants of English are w, j, ɹ, and l
Affricates
An affricate is a single sound composed of a stop portion and a fricative portion In
English t∫, the airflow is first interrupted by a stop which is very similar to t (though made
a bit further back) But instead of finishing the articulation quickly and moving directly into the next sound, the tongue pulls away from the stop slowly, so that there is a period
of time immediately after the stop where the constriction is narrow enough to cause a turbulent airstream
Trang 2322
In t∫, the period of turbulent air-stream following the stop portion is the same as the fricative ∫ English dʒ is an affricate like t∫, but voiced
Laterals
Pay attention to what you are doing with your tongue when you say the first consonant
of /li:f/ leaf Your tongue tip is touching your alveolar ridge (or perhaps your upper teeth),
but this doesn't make /l/ a stop Air is still flowing during an /l/ because the side of your
tongue has dropped down and left an opening (Some people drop down the right side of
their tongue during an /l/; others drop down the left; a few drop down both sides.) Sounds
which involve airflow around the side of the tongue are called laterals Sounds which are not lateral are called central
/l/ is the only lateral in English The other sounds of English, like most of the sounds
of the world's languages, are central
More specifically, /l/ is a lateral approximant The opening left at the side of the
tongue is wide enough that the air flowing through does not become turbulent
Voicing
The voicing parameter specifies whether the vocal folds are vibrating The vocal folds may be held against each other at just the right tension so that the air flowing past them from the lungs will cause them to vibrate against each other We call this process voicing Sounds which are made with vocal fold vibration are said to be voiced Sounds made without vocal fold vibration are said to be voiceless
There are several pairs of sounds in English which differ only in voicing that is, the two sounds have identical places and manners of articulation, but one has vocal fold
vibration and the other doesn't The θ of thigh and the ð of thy are one such pair The
others are:
The other sounds of English do not come in voiced/voiceless pairs h is voiceless, and has
no voiced counterpart The other English consonants are all voiced: ɹ, l, w, j, m, n, and ŋ
Trang 24/p/ voiceless bilabial stop / plosive
It is spelt p: plane or pp: opposite and only
exceptionally gh in hiccough
The letter p is silent when followed by
another obstruent or a nasal in word-initial
position: psalm, pterodactyl, pneumatic
/b/ voiced bilabial stop/plosive
It is spelt b: bar or bb: ribbon
The letter is silent in final position after
m: limb, crumb, dumb and in front of t in
words of Latin origin where the sound has
long been lost: debt, doubt, subtle
/t/ voiceless alveolar stop/plosive It is spelt with t: toe, with tt: cutter or with
th: Thomas, Thames
/d/ voiced alveolar stop/plosive It is spelt d: read or dd: adder
/k/ voiceless velar stop/plosive
The sound can be represented by the letter
c: comb or by cc: accuse, by k: kill, by ck: pick, by ch: architect, by qu: queen
In words like muscle and knave the letters
c an k are silent
/g/ voiced velar stop/plosive
The consonant can be rendered by g: get
by gg: begged, or by g followed by h, as in ghastly, by ua, ue or ui, as in guarantee,
guess or linguist, respectively The voiced counterpart of /ks/, /gz/ can
also be rendered by x in words like
example
/t∫/ voiceless postalveolar affricate
The phoneme is represented graphically by
ch: charm, chinchilla, rich or tch: kitchen, bitch or by t followed by u: creature,
culture when the plosive is palatalized
In words like habitual, sanctuary the
Trang 2524
pronunciation with an affricate is a variant
Exceptionally, we can have ce or cz as
graphic representations of the sound in
(violin) cello or Czech
/dʒ/ voiced postalveolar Affricate
It can be rendered graphically by j: justice, John, rejoice, pyjamas, by ge: gesture, agent, sage, by gi: giraffe, rigid; and gy:
gymnastics
In certain words it can be spelt d followed
by u: gradual, individual, procedure/al In
all these cases, however, there is an alternative pronunciation /dj/
In a number of proper names or common
nouns originating in proper names ch is
read /dʒ/: Norwich, Greenwich, S/sandwich
Another spelling can be dg in words like
ridge or edge
/m/ voiced bilabial Nasal It can be spelt with m or mm: come,
common
/n/ voiced alveolar Nasal It is spelt n or nn: dean, annual
/ŋ/ voiced velar Nasal
This phoneme has a limited distribution: it always precedes the voiceless velar plosive
or occurs in syllable-final position in front
of an elided /g/: tank, ankle, sing, long
/f/ voiceless labiodental Fricative
The sound can be spelt f: fine, fringe, feud, loaf, stifle, ff: effort, snuff, ph: physics, graph, or even gh: enough, tough
The word lieutenant /lef’tenənt/ is a
particular case
/v/ voiced labiodental Fricative
It is spelt with the letter v: vein, live, voice (Exceptionally, by ph in Stephen, nephew and f in of)
Trang 2625
/θ/ voiceless dental Fricative
The sound is rendered graphically by th:
The sound often occurs in clusters difficult
to pronounce: eighths,, depths, lengths
/ð/ voiced dental Fricative The sound is always spelt th, like its
voiceless counterpart: within, then, they
/s/ voiceless alveolar Fricative
It is spelt s, ss or c in front of e, i or y:
sour, say, hiss, assign, ceiling, cellar, cigarette, precise, cypress, bicycle
Sometimes the spelling can be sce, sci or
scy: science, scent, scene, scythe; s is silent
in words like corps, island, viscount
/z/ voiced alveolar Fricative
The sound is spelt z It is often spelt s
when the sound does not occur in initial positon: nose, easy, desire, and, exceptionally, tz in tzar
Similarly, when it marks the plural of
nouns ending in a voiced sound (e.g boys, balls, ribs) or when it is the voiced
allomorph of the 3rd person singular present indicative of verbs ending in a
voiced sound (e.g plays, calls, adds) the
Exceptionally, the sound can be spelt
double ss in words like dissolve, possess
/∫/ voiceless postalveolar fricative
It is often spelt sh in words like shoe,
It can also be spelt s: sure, sugar or ss: pressure, mission or ci: ancient, delicious, sci: conscious, ce: ocean, si: pension,
mansion, ti: tuition, retribution
It is a variant of /sj/ in words like issue, tissue
In words of French origin the sound is
spelt ch: champagne, charade, chargé,
Trang 2726
The same spelling is used in proper names like Charlotte, Chicago, Chicoutimi, Michigan
/ʒ/ voiced postalveolar Fricative
It can be spelt either s when followed by u:
visual or i: decision, or z if followed by u: seizure or ge: massage, espionage
In words like casual the alternative pronunciation /zj/ is possible, while in other cases the fricative is replaced by the
affricate /dʒ/ (e.g garage)
/ɹ/ voiced retroflex approximant The sound is spelt r: rain, ring or rr:
carry, marry
/j/ voiced palatal approximant
The sound may be spelt y (as in year)
while in words spelt with u, ue, ui, ew, eu and eau read as the long vowel /u:/ the
palatal sound is often inserted
/w/ voiced labial + velar approximant
It can be rendered graphically either by the
letter w (the most common case) (e.g
sweet) or by u (e.g quite)
/l/ voiced alveolar lateral
approximant
The phoneme is spelt either l or ll in words
like link or call, for instance In many
words, however, before plosive sounds like
/k/ or /d/ – cf chalk, could; or before nasals like /m/ or /n/ – cf calm, Lincoln;
the labio-dental fricatives /f/ and /v/ – cf
calf, calves; the lateral sound is not
pronounced
/h/ voiceless glottal fricative
The conservative spelling of English has
preserved the letter h after r in words of Greek origin where no h sound or
aspiration is heard nowadays: rhapsody, rhetoric, rheumatism, rhinal, rhinoceros, rhombus, rhyme, rhythm
