Phonetics and Phonology
Phonetics studies how speech sounds are produced, transmitted, and perceived.
Three main areas: Articulatory phonetics is the study of the production of
speech sounds.
Acoustic phonetics is the study of the physical properties of speech sounds.
Perceptual or auditory phonetics is concerned with the perception of speech sounds.
Phonology is the study of the sound patterns and sound systems of languages. It aims to discover the principles that govern the way sounds are organized in languages, and to explain the variations that occur. Begin by analyzing an individual language, then discover the rules that underlie the sound patterns of all languages.
1, how speech sounds are made?
1, Speech organs: vocal tract-- pharynx, mouth, nose
oral cavity-- mouth nasal cavity-- nose
Upper part of the pharynx:
Contents of the mouth: upper part-- the upper lip, the upper teeth, the
alveolar ridge, the hard palate, the soft palate, and the uvula
Bottom part-- the lower lip, the lower teeth, the
tongue, and the mandible
Tongue: the tip, the blade, the
front ,the back, and the root
The vocal folds: apart-- the air can pass through easily and the sound
produced is said to be voiceless
close together-- the airstream causes them to vibrate
against each other and the resultant sound is said to be voiced
totally closed-- no air can pass between them
2, the IPA The International Phonetic Association
Main principles: there should be a separate letter for each distinctive sound,
and the same symbol should be used for that sound in any language in which it appears.
The diacritics are additional symbols or marks used together with the
consonant and vowel symbols to indicate nuances of change in their pronunciation.
2, consonants and vowels
Consonants are produced by a closure in the vocal tract, or by a narrowing which is so marked that air cannot escape without producing audible friction.
Vowels is produced without such stricture so that air escapes in a relatively unimpeded way though the mouth or nose.
The distinction between vowels and consonants lies in the obstruction of airstream.
1, Consonants
Manner of Articulation: the way in which the air passes through certain parts of the vocal tract. It refers ways in which articulation can be accomplished
1, stop(or plosive)-- [p, b, t, d, k, g] 2, nasal-- [m, n, etc.]
3, fricative-- [f, v, s, z etc.] 4, approximant-- [w, j etc.] 5, lateral-- [l] 6, trill-- [r] 7, tap and flap 8, affricate
The Place of Articulation: where in the vocal tract there is approximation,
narrowing, or the obstruction of air
1, bilabial-- made with two lips
2, labiodental-- made with the lower lip and the upper front teeth 3, dental-- made by the tongue tip or blade and the upper front teeth 4, alveolar-- made with the tongue tip or blade and the alveolar ridge 5, postalveolar-- made with the tongue tip and the back of the
alveolar ridge
6, petroflex-- made with the front of the tongue tip or blade curled
back so that the underside of the tongue tip or blade forms a stricture with the back of the alveolar ridge or the hard palate
7, palatal-- made with the front of the tongue and the hard palate 8, velar-- made with the back of the tongue and the soft palate 9, uvular-- made with the back of the tongue and the uvula
10, pharyngeal-- made with the root of the tongue and the walls of
the pharynx
11, glottal-- made with the two pieces of vocal folds pushed towards
each other
2, Vowels
[ i: ]-- high front tensed unrounded vowel [ə: ]-- mid central tensed unrounded vowel [a: ]-- low back tensed rounded vowel [ɔ: ]-- mid back tensed rounded vowel [u: ]-- high back tensed rounded vowel [i ]-- high front lax unrounded vowel
[e ]-- mid front lax unrounded vowel [æ ]-- low front lax unrounded vowel [ə ]-- mid central lax unrounded vowel [ʌ ]-- low back lax rounded vowel [ɔ ]-- mid back lax rounded vowel [u ]-- high back lax rounded vowel 3, the sounds of English

3, from phonetics to phonology
1, coarticulation and phonetic transcriptions
Coarticulation: The simultaneous or overlapping articulation of two
successive phonological units.
Anticipatory coarticulation-- the sound becomes more like the following
sound (lamb)
Perseverative coarticulation-- the sound shows the influence of the
proceeding sound (map)
Broad transcription-- the use of a simple set of symbols in our
transcription
Narrow transcription-- the use of more specific symbols to show more
phonetic detail
2, phonemes
The smallest unit that distinguishes meaning of words. a unit of explicit sound contrast
Minimal pair-- a pair of words with different meanings which differ in only
one sound.
E.g. “pill” and “bill”
Phonetics transcriptions are placed between slant lines(/ /), while
phonetic transcriptions are placed between square brackets([ ]).
3, allophones
The aspirated /p/ and the unaspirated /p/ have phonetic differece, but they both belong to the same phoneme /p/. Such variants are called allophones of the same phoneme. In this case the allophones are said to be in complementary distribution because they never occur in the same context. This phenomenon of variation in the pronunciation is called allophony or allophonic variation.
To be allophones of the same phoneme, the phones must be phonetically similar. Phonetic similarity means that the allophones of a phoneme must bear some resemblance.
If two sounds occurring in the same environment do not contrast; namely, if the substitution of one for the other does not generate a new word form but merely a different pronunciation of the same word, the two sounds then are
said to be in “free variation”.
4, phonological process, phonological rules and distinctive features
1, Assimilation
Instances: nasalization, dentalization, velarization
Two possibilities-- 1, if a following sound is influencing a preceding
sound, we call it regressive assimilation
2, the converse process, in which a preceding sound is influencing a following sound, is known as progressive assimilation
Phonological process-- three aspects: 1, a set of sounds to undergo the
process
2, a set of sounds produced by the processs
3, a set of situations in which the process applies
Phonological rules
2, epenthesis, rule ordering and the elsewhere condition
A boy An apple
We treat the change of a to an as an insertion of a nasal sound. Technically, this process of insertion is known as epenthesis. 3, distinctive features
Firstly developed by Roman Jacobson as a means of working out a set of phonological contrasts or oppositions to capture particular aspects of language sounds.
Some major distinctions-- consonantal, sonorant, nasal, voiced.
5, suprasegmentals
1, the syllable structure
Monosyllabic-- with one syllable
Polysyllabic-- with more than one syllable A syllable must have a nucleus or peak.
Open syllable-- a syllable which ends in a vowel.
Closed syllable-- a syllable which ends in a consonant.
Maximal onset principle-- the principle which states that when there is a
choice as to where to place a consonant, it is put into the onset rather than the coda.
2, stress
Stress Stress refers to the degree of force used in producing a syllable. 3, intonation
Intonation involves the occurrence of recurring fall- rise patterns, each of which is used with a set of relatively consistent meanings, either on single words or on groups of words of varying length. 4, tone
In Chinese tone changes are made in a different way, affecting the
meanings of individual words.
Languages like Chinese are known as tone languages.
