Phonology
and Phonetic Transcription
Phonology
is the description of the systems and
patterns of sounds that occur in a language. It involves studying a language to
determine its distinctive sounds, that is, those sounds that convey a
difference in meaning. They later realize that these words begin with two
distinct sounds. After the final consonant, there may be a puff of air, but it
is not necessary. In fact, you could say pop and
not open your lips for hours, if it happened to be the last word you said
before going to sleep. The sound at the end would still be a p. Transcriptions of this kind are called
phonemic ranscriptions.
Languages that have been written down only comparatively recently (such as Swahili and most of
the other languages of Africa) have a fairly phonemic spelling system
.
THE
TRANSCRIPTION OF CONSONANTS
We
can begin searching for phonemes by considering the contrasting consonant
sounds in English. A good way is to find sets of words that rhyme. Take, for
example, all the words that rhyme with pie and
have only a single consonant at the beginning. A set of words in which each
differs from all the others by only one sound is called a minimal set.
Some
consonants do not occur in words rhyming with pie.
If we allow using the names of the letters as words, then we can find another
large set of consonants beginning words rhyming with pea. There is also a
contrast between the consonants in the middles of mission and vision, although there are
very few pairs of words that are distinguished by this contrast in English.
The
symbol for the voiceless palato-alveolar (post-alveolar) fricative [ S ] (long s) in shy,
sheep, rash is both an ascender and
a descender. It is like a long, straightened s going
both above and below the line of writing. The corresponding voiced symbol [ Z ] is like a
long z descending
below the line. This sound occurs in the middle of words such as vision, measure, leisure and at the beginning of
foreign words such as the French Jean,
gendarme,
and foreign names such as Zsa Zsa.
It is unfortunate that different books on phonetics use different forms of
phonetic transcription. Some other books on phonetics transcribe [ tS ] and [ dZ ] (as in church and judge) with single symbols,
such as [ c# ] and
[ K #]. These
transcriptions highlight the fact that affricates are single units by using a
single letter to transcribe them.
The
glottal stop that begins words that are spelled with an initial vowel (recall
the example from
Chapter
1 of the difference between flee east and
fleeced )
is written phonetically with [ / ],
a symbol based on the question mark. In American casual speech, the final [ t ] in words
like cat and bat can be
“glottalized”—replaced by glottal stop, or more usually pronounced with
simultaneous glottal stop (e.g., [
boet/
° ] and
[ koet/ ° ]). some
speakers of English contrast
pairs
of words such as which, witch; why, wye; whether, weather.
THE
TRANSCRIPTION OF VOWELS
The
transcription of the contrasting vowels (the vowel phonemes) in English is more
difficult than the transcription of consonants for two reasons. First, accents
of English differ more in their use of vowels than in their use of consonants. Second,
authorities differ in their views of what constitutes an appropriate
description of vowels.
One
of the principal problems in transcribing English phonetically is that there
are more vowel sounds than there are vowel letters in the alphabet. In a transcription
of the English word sea as [si ], the [ i ] represents
a similar (but not identical) sound to that in the Spanish or Italian si. But unlike Spanish and Italian,
English differentiates between vowels such as those in seat, sit, and
heed, hid. The vowels in seat, heed differ from those in sit, hid in two ways:
They
have a slightly different quality and they are longer. Because the vowels in sit, hid are somewhat like those
in seat, heed, they are represented
by the symbol [ I ],
a small capital I.
In
British English, [ E ] is
usually the sole component of the -er part
of words such as brother,
brotherhood,
simpler [ "brODE, "brODEhAd, "sImplE
]. In forms of American English with r-colored vowels, these words are usually
[ "brODE},
"brODE}hAd, "sImplE} ].
As with the symbol [ Î } ],
the small hook on [ E} ] symbolizes
the r-coloring.
Both [ E ] and [ E} ] are very
common vowels, [ E ] occurring
very frequently in unstressed monosyllables such as the grammatical function
words the, a, to,
and, but. In connected speech,
these words are usually [ DE, E, tE, End, bEt ].
CONSONANT
AND VOWEL CHARTS
So
far, we have been using the consonant and vowel symbols mainly as ways of
representing the contrasts that occur among words in English. But they can also
be thought of in a completely different way. This is
because it is articulated with both a narrowing of the lip aperture, which
makes it bilabial, and a raising of the back of the tongue toward the soft
palate, which makes it velar. The affricate symbols [otSo] and [odZo] are not listed separately in
the table even though they are contrastive sounds in English. The consonant
chart has twentythree different symbols, but only eleven basic gestures of the
tongue and lips are needed to make these different sounds. The sounds [op, b, mo] are all made with the same
lip gesture, and [ot, d, no] and [ok, g, No] with the same tongue gestures. The
airstream process involves pushing air out of the lungs for all the sounds of
English. The phonation process is responsible for the gestures of the vocal
folds that distinguish voiced and voiceless sounds, and the oro-nasal process
will be active in raising and lowering the velum so as to distinguish nasal and
oral sounds.
PHONOLOGY
As we have noted, some of the phoneme symbols may represent
different sounds when they occur in different contexts. For example, the symbol
/ t / may represent a wide variety of sounds. In tap /
toep /, it represents a voiceless alveolar stop. But the / t / in eighth / eItT / may be made on the teeth, because of the influence of the
following voiceless dental fricative /oT /. This / t / is more accurately called a voiceless dental stop, and we will
later use a special symbol for transcribing it. In most forms of both British
and American English, the / t / in bitten
is accompanied by a glottal stop, and we will also be using a special symbol
for this sound.
Each
of them occurs in a specific place: / t
/ before / T /
is a dental stop, / t /
before a word final / n /
is a glottal stop, and / t /
after a vowel and before an unstressed vowel is a voiced stop. None of these
variations is different enough to change the meaning of a word in English. Note
also that all of these variations occur in citation speech and are not simply
the result of failing to “hit the target” when speaking quickly. Similarly,
other symbols represent different sounds in different contexts. The symbols / l / and / r / normally
stand for voiced approximants. But in words such
as ply / plaI / and try / traI /, the
influence of the preceding stops makes them voiceless. Vowel sounds also vary.
The / i / in heed / hid / is
usually very different from the / i
/ in heel /
hil /, and much
longer than the / i /
in heat.
The term broad transcription is
often used to designate a transcription that uses the simplest possible set of
symbols. Conversely, a narrow transcription is
one that shows more phonetic detail, either by using more specific symbols or
by representing some allophonic differences. A narrow
(but still phonemic) transcription could be / pli…z / and / trIp /. This transcription would be phonemic as long as we always used
/oi… / wherever we would
otherwise have had / i /. In this way, we would not be showing any allophones of the
phonemes. A narrow allophonic transcription would be [ pli9 …z ] and [ trI9 p ], in which [ l 9] and [ r 9]. are allophones of / l / and / r /.
