INTRODUCTION TO ENGLISH PHONETICS
A. Theory
# Organs of speech: inwards
Fig 1. Organs of Speech
Lips (upper and lower) / nasal cavity (khoang mũi)  teeth (upper and lower)  alveolar ridge
(chân răng)  toungue (tip, blade, front, back or root) / hard palate (ngạc cứng)  soft palate
(ngạc mềm)  uvula (lưỡi gà)  pharynx (glottis – hầu / họng)  epiglottis (nắp thanh quản) 
larynx (thanh quản)  vocal folds (vocal cords - dây thanh)  trachea (khí quản) / oesophagus
(thực quản) ( lungs).
1. Define Phonetics and Phonology?
- Phonetics is the study of speech sounds which are utilized by all human languages to represent
the meaning. It concerned with the describing the speech sounds which occur in the languages of
the world.
- Phonology is the description of the systems and patterns of sounds that occur in a language.
Phonology deals with how these speech sounds are organised into systems for individual
language.
2. What are the stages of speech chain during human communication in sounds?
Stages of speech chain are the steps in which the sounds are produced and used for
communication. These stages of speaker differ from those of listener.

- Speaker: 3 stages
+ Psychological stage: idea is transmitted to the brain throught the 5 senses of human. It is
the process of thinking and choosing what to say.
+ Physiological stage: idea is transmitted to the brain and then to the mouth through nervous
system.
+ Physical stage: the process of producing and articulating the sounds. The mouth works to
speak out the sounds.
- Listener: such stages are simplier. Nervous system carries the sounds from the ears up to the
brain. The brain will analyse the sounds.
3. What is the difference between pulmonic egressive airstream mechanism and ingressive
airstream mechanism? What airstream mechanism do English sounds belong to?
The difference between these two mechanism is the direction of the airstream. In pulmonic
egressive mechanism, the airstream move outwards from the lung to the trachea (windpipe – khí
quản) to pharynx (họng) and to the mouth, but the airstream in pulmonic ingressive mechanism
move inwards from the outside.
English sound belong to the pulmonic egresive airstream mechanism and this mechasnism is also
used in almost languages in the world.
4. What is voiced, voiceless sound? In what way(s) are voiced sounds different from voiceless
ones?
- Voiced sounds are the sounds produced by the rapid opening and closing of vocal cords. In a
voiced sound, the rapid opening and closing of vocal cords is a kind of vibration.
- Voiceless sound are the sounds made with vocal cords drawn apart so that the air can pass out
freely between them and there is no vibration.
Voiced and voiceless sounds can be distinguished according to the following criteria:
Criteria
Voiced sound
Voiceless sound
State of the vocal cords
Rapid opening and closing
Are drawn apart
The airstream from the lungs
Being obstructed by the vocal Passes out freely
cords
Vibration
Made by the rapid opening and There is no vibration
closing of the vocal cords
5. What is the difference between articulatory phonetics and acoustic phonetics?
Articulatory phonetics studies the physical processes involved in speech production while
acoustic phonetics deals with the physical properties of speech sounds (linguistically relevant
acoustic properties).
Articulatory phonetics examines:
-
The airstream mechanism: where the air used in speech starts from, and which direction it
is travelling in
hoanguyen

Answers to Phonetics and Phonology
www.soflstudent.weebly.com
-
The state of the vocal cords: wherether or not the vocal cords are vibrating, which
determines voicing
-
The state of the velum: whether it is raised or lowered, which determines whether the
sound is oral or nasal
-
The place and manner of articulation: the horizontal and vertical positions of the tongue
and lips
Acoustic phonetics studies the specific and measurable effects on the air involved in the
production of the speech sound.
6. What is the difference between a vowel and a consonant in the English language? Give
example to illustrate?
 Definition:
- Consonants are speech sounds produced by creating an obstruction to the airstream during the
articulation.
- Vowels are speech sounds where the airstream escapes the oral tract (organs of speech)
unobstructed.
 Differences: vowel and consonant can be distinguished according to the following criteria:
Criteria
Vowel
Airstream
Escapes freely from the oral Being obstructed on the way
tract
out from the lungs
Nasal or oral
All vowels are oral sounds as Consonants may be nasal
the velum is raised while the when the velum is lowered
sounds are produced
or oral when the velum is
Eg. /i:/, /u:/, / :/, / :/, / :/; raised
/ /, / /, / /, / /, / /, / /, / /
Consonant
Eg. /m/, /n/, / / (nasal); /p/,
/d/, /k/, / /…(oral)
7. Classify English speech sounds?
English speech sounds can be classified according to the following criteria: voicing, state of the
velum, state of the vocal cords
- According to voicing criteria, English speech sounds can be divided into: voiced and voiceless
sounds.
Eg.
Voiced sounds such as: /b/, /v/, /d/, / /, /z/, / /, / /…
Voiceless sounds such as: /p/, /f/, /t/, /k/, /s/, / /, / /…
- According to the state of the velum, there are nasal and oral sounds.
Eg.
Nasal sounds: /m/, /n/, / /
Oral sounds: /b/, /v/, /d/, / /, / /, / / (consonants), or / /, / /, / /, / /, / /
(vowels)
- According to the state of the vocal cords, there are vowel and consonant.
Eg.

B. Practice
1. Fill in the blanks in the following passage
There are three principal airstream mechanisms: the pulmonic airstream mechanism, the velaric
airstream mechanism and the glottalic airstream mechanism. In normal utterances in all languages
of the world, the airstream is always flowing outwards if the pulmonic egressive airstream
mechanism is involved. Stops made with this mechanism are called plosives (tắc). The only
mechanism that is used in some languages to produce some sounds with inward going air and
some sounds with outward going air is the glottalic airstream mechanism. Stops made with this
mechanism acting ingressively are called implosives (đóng). Stops made with this mechanism
acting egressively are called ejectives (bật). The mechanism which is used in the language to
produce sounds only with inward going air is the velaric airstream mechanism. Stops made with
this mechanism are called clicks.

CONSONANTS
# Definitions:
-
Consonants are speech sounds produced by creating an obstruction to the airstream
during the articulation.
-
Voiced sounds are sounds produced by the rapid opening and closing of the vocal cords.
In a voiced sound, the rapid opening and closing of the vocal cords is a kind of vibration.
-
Voiceless sounds are sounds made with vocal cords drawn apart so that the air can pass
out freely and there is no vibration.
-
Fortis are consonants which are tend to be articulated with relatively strong energy. They
are voiceless sounds and usually shorten the preceeding vowel.
Eg. bat
-
Lenis are consonants which are tend to be articulated with relatively weak energy. They
are voiced sounds and usually lengthen the preceeding vowel.
# Criteria to classify English consonants:
-
Place of articulation
-
Manner of articulation
-
State of the velum (nasal or oral)
-
Position of the vocal cords (voiced or voiceless)
-
Force of articulation / degree of muscular tension (fortis or lenis)
!!! To descript an English consonant we should descript the following aspects:
Voicing  place of articulation  manner of articulation ( place of velum  force of
articulation)
Eg. p: voiceless – bilabial – plosive (– oral – fortis)

A. Theory
1. Classify all the English plosives, providing the words containing the sounds.
English plosives are classified according to the following 3 criteria:
- According to the place of articulation: there are 3 types
hoanguyen

Answers to Phonetics and Phonology
www.soflstudent.weebly.com
+ Bilabial plosive: /p/, /b/
eg. pet, pay, big, boy
+ Alveolar plosive: /t/, /d/
eg. tape, talk, date, dog
+ Velar plosive: /k/, / /
eg. key, kitchen, go, gap
- According to position of the vocal cords: voiced and voiceless
+ Voiced plosive: /p/, /t/, /k/
eg. pet, pay, tape, talk, key, kitchen
+ Voiceless plosive: /b/, /d/, / /
eg. big, boy, date, dog, go, gap
- According to force of articulation:
+ Fortis plosive: /b/, /d/, / /
eg. big, boy, date, dog, go, gap
+ Lenis plosive: /p/, /t/, /k/
eg. pet, pay, tape, talk, key, kitchen
2. List the bilabial consonants. For each bilabial, provide one word containing it.
There are 4 bilabial consonants in the English language: p, b, w, m
- Bilabial plosive: /p/, /b/
eg. pet, pay, big, boy
- Bilabial approximant: /w/
eg. wait, watch
- Bilabial nasal: /m/
eg. mother, meet
3. What is the distinctive feature that makes /p/ and /b/ different sounds?
/p/ and /b/ are bilabial plosive consonants, but the distinctive feature that makes them different
sounds is the voicing. /p/ is a voiceless consonant while /b/ is a voiced one. We can realize such
difference when these sounds are articulated by touching the Adam’s apple. When /b/ is
articulated, there is a vibration, but there is no such vibration when /p/ is pronounced.
4. According to what are English consonants classified? Give examples
English consonants are classified according to 5 criteria:
 According to place of articulation:
- Bilabial: p, b, w, m
eg. pay, boy, wait, man
- Labiodental: f, v

5. What are the differences between a plosive and an affricate in English?
Criteria
Airstream
Plosive
Affricate
The airstream is stoped in the oral or
nasal cavity by the as the lips contact
or the soft palate raises forming a velic
closure
The tongue comes up to make a
contact with the alveolar ridge to form
a stop closure and this contact is then
slacken (loosen) to make a fricative.
Number of Plosive
manners
involved
The combination between plosive and
fricative
6. What is the distinction between an alveolar plosive and an alveolar fricative?
The distinction between an alveolar plosive and an alveolar fricative is the airstream: in alveolar
plosive, the soft palate is raised so that the nasal tract is blocked off, then the airstream is
completely obstructed while in an alveolar fricative, the close approximation of two articulators
caused the airstream partially obstructed and turbulent airflow is produced.
7. Classify the English fricatives according to the criteria for classification of the sounds.
Give the words containing these consonants.
English fricatives can be classified according to the following criteria:
- Accroding to the Place of articulation:
+ Labiodental fricative: f, v
eg. fingure, fan, vapour, van
+ Dental fricative:
eg. think, this
,
+ Alveolar fricative: s, z
+ Palato-avleolar fricative:
+ Glottal fricative: h

Monothong is a pure vowel sound which is pronounced without changing of the position
of the organ of speech throughout the duration of the vowel articulation.
-
Dipthong is a complex sound consisting of two vowel elements pronounced so as to form
a single syllable. In the pronunciation of dipthong, the position of organ of speech starts in
the position of one vowel and glides gradually to the other one.
Description of English vowel:
Monothong: Height  Position  Shape  Length  Degree (of articulation).
Diphthong: Height + Pisition (1st vowel) glides to Height + Position (2nd vowel).

a. Aspirated
Symbol: [ ]
[- voiced, + plosive]  [+ aspirated] when syllable initial.
Means: voiceless plosive sounds (/p, t, k/) will be aspirated as they are the initial syllable, or when
they stand in initial position of a stress syllable.
Eg. car [
:]
important [
/]
top [
]
b. Unaspirated
Symbol: [=]
[- voiced, + plosive]  [- aspirated] when standing:
+ after /s/ at the beginning of the syllable; or
+ in medial or final position of a syllable
Eg. sport [
=
] happy [
=
]
map [
=

[- voiced, + plosive]  unexploded before another [+ plosive]
Eg. act [
]
adapt [
]
looked [

3. Dentalization
Symbol: [
]
[+ alveolar]  [+ dental] before [+ dental], means that alveolar (/t, d, s, z, l, n/) will be
dentalized when it stand before a dental sounds (/ , /).
Eg. eighth [
] width /

]
cook [
] - / / and / / are pronounced longer.
5. Devoicing
Symbol: [
]
[+ approximant]  devoiced after [+ aspirated, + plosive]
Approximant (/w, r, j, l/) will be devoiced when stand after aspirated plosive.
Eg. play [
]
cry [

ASPECTS OF CONNECTED SPEECH
A. Theory
1. What is assimilation in the English language? Give example
Assimilation is a process when one sound adapts itself to the neighbouring sound so that it
becomes close to the assimilating one in one or more aspects.
Eg.
in the [
][
]
][
right place [
]
2. What is elision / liaision? Give example
Elision is the missing out of a consonant or vowel or both in informal spoken English or in rapid
speech in English.
Eg.
hoanguyen
acts [
] - / / will be disappeared in the articualtion of the word.
19

Answers to Phonetics and Phonology
looked back [
www.soflstudent.weebly.com
] - / / will be disappeared in the articualtion of the
word.
today [
] - / / is disappeared
potato [
] - / / is disappeared
Liaision is a phenomenon where a sound is linked to another in informal speech.
Eg.
come in [
] set up [
]
3. What is the difference between progressive assimilation and regressive assimilation?
Prove it.
Consider a case where two words are combined, the first word ends with a single final consonant
(Cf) and the second one starts with a single initial consonant (Ci).
We have the following construction: Cf
Ci
In progressive assimilation, the initial consonant (Ci) changes to become like the final consonant
(Cf) in some ways, whereas (Cf) changes to become like (Ci) in some aspects in regressive
assimilation.
Eg.
regressive assimilation:
][
good morning [
][
one more [
progressive assimilation:
][
in the [
];
]
]
4. What is the difference between elision and liaision? Prove
Elision is the missing out of the consonant or vowel or both in informal spoken or rapid speech,
whereas liaision is the linking of a sound to another in informal speech.
Eg.
today [
Eg.
come in [
] - / / is disappeared (elision)
] set up [
] (liaision)
5. Give example of liaision of consonant and vowel
Liaision is the phenomenon in which a sound is linked to another in informal speech.
Eg.
come in [
] (final consonant + initial vowel)
my turn [
: ] (final vowel + initial consonant)
6. What are the types of assimilation? Give example
a. According to the direction of change
- Regressive assimilation: Ci  Cf
Eg.

STRESS
A. Theory
1. English word stress and its functions?
a. Definition
Stress is the pronunciation of a syllable with more force than the surrounding ones, that means the
way the speakers use energy created from the lungs to make a syllable more prominent than the
others. The salience of a sound or syllable is called stress.
b. Functions
 Grammatical / syntactic function:
-
Stress is used to change the word class without changing in the writing of the word. (noun
has stress on the first syllable and verb has stress on the second syllable)
Eg.
abstract [
transport [
-
] (n) – transport [
] (v)
] (v)
Stress is used to distinguish compound words from a free combination of words (if the
stress is on the first element – compound; if stress is on both elements – free combination)
Eg. whitehouse [
combination)
-
] (n) – abstract [
] (compound) – white house [
] (free
Stress is used to indicate grammatical structure of the words
Eg.
diplomat [
diplomacy [
hoanguyen
] (n) – person who works in diplomatic field
] (n) – skill in dealing with people

another.
 Stress helps to form the intonation.
2. What is meant by “prominence of a stressed syllable” in English?
All stressed syllable have the one characteristic in common which is called prominence, means
that this characteristic helps to distinguish stressed syllable from unstressed one.
3. What is the nature of English word stress?
The nature of English word stress includes four factors:
-
Loudness: stressed syllable is louder than unstressed one.
-
Length: stressed syllable is pronounced longer than unstressed one.
-
Pitch: stressed syllable has higher pitch than unstressed one.
-
Quality of neighbouring vowel: the vowel of stressed syllable is different from the others
4. Placement of stress within word
a. Stress on simple words:
 Two-syllable words:
-
Verbs:
+ Stress is marked on the second syllable if it contain a long vowel or diphthong or ends
with more than one consonants.
Eg. apply [
]
attract [
]
+ Stress is on the first syllable if final syllable contains short vowel and one (or no)
consonant.
Eg. enter [
] open [

INTONATION
A. Theory
1. English intonation and its function?
a. Definition
When speaking, people generally raise the pitch of their voice forming pitch pattern. They also
