Phonetics, Phonology, and Phonics
Humans have a complex system of using sounds to produce language. The
study of linguistic sounds is called Phonetics. Phonology is the
study of systems of sounds, often the sound system of a particular language.
Many people are familiar with the term Phonics. This is a method of
teaching reading and writing using sounds.

Phonetics
Linguistic sounds are produced by pushing air from the lungs out through the
mouth, sometimes by way of the nasal cavity. The movement of the air can then be
manipulated by the anatomy of the mouth and throat to produce different sounds.
In actual writing, the same sound may often be spelt different ways. For instance, George Bernard Shaw once pointed out that the word fish could as easily be spelt ghoti, since gh has the same sound in enough, o has the same sound in women, and ti has the same sound in nation. This makes sounds very hard to study without a more precise indication of what sounds we are referring to. The solution is to adopt a phonetic alphabet which always has the same spelling for the same sound. Linguists use phonetic alphabet called the International Phonetic Alphabet (IPA). In the IPA, the word fish would be spelt [fö§ ]. Many IPA letters are the same as those of the English alphabet, so we place IPA spellings in square brackets to indicate that they are phonetic spellings. Note that many dictionaries give phonetic spellings as pronunciation guides, but not all dictionaries use the IPA. Likewise, the system of Phonics does not use the IPA. When looking at phonetic spellings, make sure you know what system you are using. Note also that linguists in the United States do not always follow the accepted international standard. For instance, most linguists in the United States would transcribe fish as [föš]. The individual differences will be described under the section on Phonology below.
Consonants
Consonants are produced by restricting and then releasing the flow of air in
three ways: vibrating the vocal cords, changing the part of the anatomy which
restricts the air flow, and changing the extent to which the air flow is
restricted.
Consonants with relatively little vibration of the vocal cords are called voiceless consonants. Consonants with relatively more vibration of the vocal cords are called voiced.
Consonants fall into the following categories, depending on what part of the anatomy is used to restrict the air flow:
Labial |
Air flow is restricted with the lips. |
Dental |
Air flow is restricted with the teeth. |
Labiodental |
Air flow is restricted with the top teeth on the bottom lip (if both lips are used the sound is called bilabial). |
Alveolar |
Air flow is restricted by placing the tongue on the hard plate (alveolum) behind the top front teeth. |
Palatal |
Air flow is restricted by placing the tongue on the soft palate behind the alveolum. |
Velar |
Air flow is restricted by placing the tongue far back in the mouth. |
Glottal |
Air flow is restricted by tightening the folds in the vocal cords (glottis). |
Consonants can also be categorised by the extent to which the air flow is restricted:
Stop |
Air flow is stopped and released quickly. |
Fricative |
Air flow is released gradually. |
Affricate |
Air flow is stopped and released gradually. |
Nasal |
Air flow is channeled through the nasal cavity. |
Liquid |
Air flow is channeled around the sides of the tongue. |
Glide |
Air flow is only partially restricted (these sounds are often called semi-vowels). |
Some languages have other categories, but only the ones above are the only ones that occur in English.
Individual consonants can be made up of nearly any combination of the features above. For instance, [b] is a voiced labial stop and /s/ is a voiceless alveolar fricative.
Vowels
Vowels are produced by directing the flow of air into different parts of the
mouth. They can be adjusted by changing the position of the tongue, by rounding
of the lips, and by the degree of opening of the mouth. All vowels are voiced.
The position of the tongue can be described in terms of how far forward the tongue is and how high it is. Vowels are categorised as follows, depending on the position of the tongue:
Front |
The tongue is in the front of the mouth. |
Central |
The tongue is further back in the mouth. |
Back |
The tongue is in the back of the mouth. |
High |
The tongue is high in the mouth. |
Mid |
The tongue is lower in the mouth. |
Low |
The tongue is low in the mouth. |
All vowels can be described in terms of their location on both vertical and horizontal axes. A look at the Spanish vowel system demonstrates this. Examine the underlined vowels and the descriptions of them below:
Niño "boy" |
High Front Vowel |
Jose |
Mid Front Vowel |
Mar "sea" |
Low Central Vowel |
Jose |
Mid Back Vowel |
Burro "donkey" |
High Back Vowel |
All vowels can be described in terms of their location on both vertical and horizontal axes. A look at the Spanish vowel system demonstrates this. Examine the underlined vowels and the descriptions of them below:
If you pronounce the High and Mid Back Vowels, you will find that you round your lips. These are called rounded vowels.
The English vowel system is more complicated than the Spanish one. In English we create extra vowels by opening the mouth more or less. When the mouth is relatively more open, the vowel is called lax. When the mouth is relatively more closed, the vowel is tense. Compare the following English words:
Machine |
Tense High Front Vowel |
Chin |
Lax High Front Vowel |
Ballet |
Tense Mid Front Vowel |
Get |
Lax Mid Front Vowel |
Salute |
Tense High Back Vowel |
Pull | Lax High Back Vowel |
Foal | Tense Mid Back Vowel |
For | Lax Mid Back Vowel |
Phonology
Consider the sound of the consonant in the English word the. This sound is a voiced dental fricative. In French, this sound does not exist, which is why English spoken with a French accent is famous for replacing it with a voiced alveolar fricative z, which is very similar. The reason for this is that the number of linguistic sounds which humans can produce is greater than the number which actually occurs in each language. When studying an individual language, like English, we can therefore focus in only the sound that occur in that language and the system by which they relate to each other. Studying a system of sounds is called phonology.
When looking at the phonological system of an individual language, we limit our study to those sounds which are perceived by speakers as distinct and capable of indicating some grammatical significance. Sounds which meet these criteria are called phonemes. For instance, the [l] and [r] are perceived as distinct and help us understand the difference between lice and rice. However, [l] and [r] are not distinct phonemes in many Asian languages, which is why speakers of those languages often have trouble distinguishing the two words when speaking English. Linguists use the IPA to represent phonemes but indicate that they are phonemes by placing them between slashes. Thus the word fish is rendered /fö§/ (US /föš/). This is called phonemic transcription, as opposed to the phonetic transcription described above. In general, it is only necessary to use phonemic transcription when studying the English language. Phonemic transcriptions represent the pronunciation of a word and the precise number of phonemes in the word. Thus the word fish has three phonemes, which can be seen clearly in the transcription /fö§/ (US /föš/).
The following is a list of phonemes in US English:

Note that /l/ and /r/ have range of positions, they are placed in the alveolar and palatal columns only for convenience.
The following equivalencies between International and US usage should be observed:
International = US
/§/ = /š/
/½/ = /ž/
/t§/ = /č/
/d½/ = /ĵ/ (Note: the "^" in "/ĵ/" should be upside down as in "/š/" but I cannot get this on the computer display.)
/j/ = /y/
In general, the symbols are interchangeable, but I recommend not using /y/, since this symbol is also used for a vowel sound (the sound in French lune "moon" or German über "over"). This sound was historically quite common in English as well.
Below is a list of IPA spellings of English words. You may not recognise some of the symbols for the vowels.

The High Back and Mid Back vowels are rounded.
Before looking at some sample words, it is necessary to state that this table is a simplified representation of actual speech. The positions of the low sounds are very unstable, and the /a/ sound may be central or back, depending upon the speaker (some linguists use /Œ/ or // to represent the back version). In American pronunciation the vowel /¿/, which tends to occur in words with o, au, ou, and aw spellings, has been almost completely been replaced by /a/. So you may find it hard to hear if you pronounce the word hot with the same vowel as in father. You may think of the vowel /¿/ as the vowel in hot, spoken with a British accent. Most American speakers still pronounce /¿/ before /r/, as in for.
The mid central vowel /\/ has a special name; it is called a schwa. This vowel, and the slightly lower /Ã/, will be discussed under Syllable Structure and Word Stress below.
Monophthongs and Diphthongs
The vowels shown above are all pronounced in one part of the
mouth. These are called monophthongs. English also possesses vowels which are
pronounced in two contrasting parts of the mouth, called diphthongs. Note
the spelling "phth" in both words.
The diphthongs in English are as follows:
Back-Front |
Back-Back |
|
Low-High |
/ai/ |
/au/ |
Here are some examples of how these sounds are pronounced:
high /hai/
boy /boi/
house /haus/
Note that many students incorrectly try to transcribe the sound in high with /ö/. The symbol /ö/ indicates the monophthongal sound in bitter /böt\r/, and the symbol /ai/ indicates the diphthong in biter /bait\r/.
The pronunciation of diphthongs varies a good deal in English, which means that linguists often transcribe them in other ways. The following table contains some of the acceptable alternative transcriptions which you may encounter. You may choose any of these if you feel that they more closely reflect your pronunciation.
/ai/ |
/aö/, /Œi/, /Œö/, /aj/, /Œj/ |
As you can see, some people interpret the second element of a diphthong as a glide consonant. However, I suggest that you avoid these transcriptions, since they make the syllabification rule given below more complicated.
Note that the historical English monophthongs /i/, /e/, /u/, and /o/ are largely pronounced as diphthongs today (something like /ij/, /ei/, /uw/, and /ou/ respectively). You can detect this if you listen to an English speaker pronounce the Spanish name Jose. Apart from the pronunciation of the s as /z/, the English speaker’s diphthongal pronunciation of o and e is responsible for the noticeable English accent. In Spanish, these vowels are true monophthongs. However, in an introductory course like this one, it is not necessary to use separate transcriptions for /i/ and /ij/, /e/ and /ej/, etc., since the sounds are so similar. You may represent these sounds as monophthongs.
Syllable Structure
A word like measure has two syllables. In order to
identify which phonemes are in the first syllable and which are in the second,
we need to look at the pattern of vowels and consonants. We can represent each
consonantal phoneme with "C" and each vowel (vocalic) phoneme with
"V". Hence measure /m«½\r/
would be "CVCVC". Notice that the pattern is based on the number of
phonemes, not the number of letters in the English spelling.
In order to have a syllable, you must have a vocalic phoneme, which may or may not be accompanied by consonants on either side. So "CVCV" has two syllables because it has two vowels. In English, there are only two significant syllable patterns: "VCV" and "VCCV". In other words, English has syllables divided by one consonant or more than one consonant (it does not matter if the first vowel is preceded by a consonant or if the second vowel is followed by a consonant). As you can see, measure follows the "VCV" pattern. The syllable division for each type is as follows:
V | C V
V C | C V
Note that English words with double consonants (like bitter) can be tricky. The double consonant tells us something about the preceding vowel (compare biter), not that the word has two consonant phonemes. Words like bitter really follow the "VCV" pattern in English.
Nasal and liquid consonants can sometimes be vocalic; that is, they combine the functions of vowels and consonants. Linguists represent this function by placing a small circle underneath the IPA symbol. But do these consonants constitute separate syllables? This is a more complex issue than can be dealt with in an introductory course, and we will not go too far astray if we avoid the issue. If you perceive a consonant to be vocalic, it is best to simply insert a "dummy" vowel into your transcription. The best choice is to use the schwa (/\/). Hence the word golden would be transcribed /gold\n/.
Word Stress
Words of more than one syllable have differing degrees of stress
on each syllable. Stress is indicated by a combination of higher pitch
and louder volume, but many students find it difficult to identify which
syllable is stressed. To practice, try making a list of words with more than one
syllable and guessing which syllable is stressed. Then go to a dictionary which
gives a pronunciation guide and see which syllable is marked as stressed. Most
dictionaries mark stress by placing a small tick before the beginning of the
syllable.
In English, the vowels of unstressed syllables have often changed historically. The spelling often indicates the original sound, but over time, the number of vowels that occur in unstressed vowels has diminished. In general, unstressed vowels tended to become /\/, especially in suffixes with grammatical significance (e.g. plural –es, present tense –es, past tense –ed, and past participle –en). In some varieties of English, including US English, this sound alternates with /ö /, depending upon the word: compare village /völöd½ / (or /völöĵ/) with cower /kau\r/. There is no rule for which words contain which of these vowels, and, in general, I will accept either one. If in doubt, use the schwa (/\/).
Sometimes the mid central vowel /Ã/ appears in a stressed syllable, as in sun /sÃn/. The sound can be distinguished from schwa by pronouncing the word oven /Ãv\n/. However, some textbooks simplify things by using the symbol /\/ for all mid central vowels (e.g. /\v\n/). You may choose to adopt this simplification if you find it helpful.
In some cases, historically unstressed vowels have disappeared completely, although we may still spell them. The most famous example is the so-called "silent e" in words like name /nem/ and begged /begd/. Make sure that you do not transcribe these as two-syllable words.
Phonetic Processes
A wide variety of sound changes take place when certain sounds
come into contact with each other. The most important is called assimilation.
This process is best illustrated by comparing the words incapable and impossible.
Both words contain the prefix in-, which makes the adjective negative.
However, the prefix is pronounced /ö n/
or /ö m/, depending on
whether or not the following consonant is labial. If it is, the alveolar /n/
becomes a labial /m/, assimilating the quality of the following labial
consonant.
A particularly important occurrence of assimilation is in words with the grammatical endings (plural or present tense –s and past tense or past participle –d). Consider the following words and their pronunciations:
cats /k¾ts/
dogs /d¿gz/
thinks / inks/
scolds /skoldz/
worked /w\rkt/
begged /begd/
In each case, the grammatical ending varies between voiceless /s/ or /t/ and voiced /z/ or /d/, depending on whether or not the preceding consonant is voiced or voiceless. In a few cases, the consonant in the grammatical ending is assimilated to a preceding vowel:
horses /h¿ rs\z/
scolded /skold\d/
Since all vowels are voiced, the consonants that follow them in these grammatical endings also become voiced.
Transcription Examples
The discussion above will allow you to transcribe most English
words successfully. Some examples are given below.
fish /fö§/ (US /fö š/)
Phonics
Teachers often use a methodology called phonics to teach
reading and writing skills. This methodology recognises that English spellings
do not always clearly relate to pronunciation, and that learning the spelling
system involves the ability to recognise how the individual phonemes pronounced
in words correspond to conventional spellings. This is not a course on the
methodology of phonics, but it is useful to ask some questions about how English
spellings relate to pronunciation. We may make the following observations:
The last two points show that many of the differences between spelling and pronunciation are the result of historical circumstances. Our modern spellings conventions were mostly worked out in the fifteenth to seventeenth centuries and were based on pronunciations which have long since changed. Consider, for instance, the word know, which was once pronounced /kn¿w/, but is now pronounced /no/. The spelling represents the earlier pronunciation, not ours today. Sometimes we can even see these changes taking place, for instance, in the word coupon. You are probably familiar with the older pronunciation /kupan/, but you may use the more recent pronunciation /kjupan/.
Sometimes people ask why we don’t reform our spelling system so that it reflects today’s pronunciation and so that it is easier to learn. There are even political organisations created with this goal in mind. Here are some reasons why no major reform of the English spelling system has taken place.
However much we may struggle with the English spelling system, its advantages outweigh its disadvantages. Nevertheless, it has been shown that acquiring a phonemic awareness, the ability to perceive the phonemic content of a word without reference to its spelling, can help minimise the difficulties we may encounter in reading and writing because of the idiosyncrasies of English spelling conventions.
