classification of speech sounds -...
TRANSCRIPT
Since the writing system of English does not provide us
with a one-to-one correspondence between oral sound
and written symbol, we need a tool for representing
human sounds in an regular way when studying
phonology;
the International Phonetic Alphabet (the IPA) has been
invented for this purpose. In it, each written symbol
represents one, and only one, speech sound, while each
speech sound is represented by one, and only one,
written symbol.
We will begin by learning this special alphabet.

So….
Consonants might be considered of greater
importance than vowels in English.
Text message English – a limited use of vowels
Consonants
A consonant is defined as a speech sound which is articulated withsome kind of stricture, or closure, of the air stream.
Consonants are classified according to four features:
1. the state of the glottis: in vibration (voiced) or open (voiceless);
2. the state of the velum: lowered (nasal) or raised (oral);
3. the place of articulation: the location where the stricture or place ofmaximum interference occurs and what articulators are involved; and
4. the manner of articulation: the amount of stricture, whether it iscomplete, partial (called “close approximation”), or relatively open(“open approximation”).
Oral or nasal consonants
Oral: the air escapes through the mouth.
Nasal: the air escapes through the nose.
Almost all consonants are oral, only 3 are nasal: /m, n, [ŋ].
Voiceless and voiced consonants
Voiceless: no vibration of the vocal cords.
Voiced: vibration of the vocal cords.
Voiceless consonant phonemes are: /p/ as in pea; /t/ as in tea; /k/ as
in coffee; /f/ as in fat; /θ/ as in thin; /s/ as in see; /ʃ/ as in she; /h/ as
in he.
Voiced consonant phonemes are: /b/ as in ball; /d/ as in dog; /ʤ/ as in
joke; /g/ as in good; /v/ as in van; /ð/ as in that; /z/ as in zoo; /m/ as in
mouth; /n/ as in no; /ŋ/ as in thing; /l/ as in love; /r/ as in right; /w/ as in
why; /j/ as in you.
Places of articulation
They indicate the place where obstruction is made for the
pronunciation of the consonants.
The tongue, lips, teeth, and various regions of the mouth
constitute places of articulation in the oral cavity.
Bilabial, Labiodental, Dental or Interdental, Alveolar, Palato-alveolar,
Palatal, Velar, Glottal.

Manner of articulation
It refers to the way the articulators are set so that the resonance effect is possible.
Stop or plosive
Fricative
Affricate
Nasal
Lateral
Glide
Liquid
Approximant (in English lateral, glide and liquid sounds are approximants, as they
don’t involve friction in any part of the vocal tract.

Allophones
In natural speech production sounds occur in
groups in fast succession so individual sounds are
influenced by the sounds around the.
If /t/ occurs before a vowel it is aspirated more than
if it occurs before a /r/. Ex. Say: table and train.
In some varieties of English (American English,
Cockney) [t] can have up to 6 different realisations,
these are called phonetic variants or allophones.
In transcription they are represented by diacritic
symbols added to the phonemic ones.
They do not involve any change of meaning but
differences in accents.

Vowels
To adequately define a vowel, we need to look at it in articulatory, acoustic, andfunctional terms:
In articulatory terms, vowels are sounds articulated with no –– obstruction of the airstream, that is, with open articulation. There is lack of central closure of the air stream,though the tongue may come into contact with the teeth on the sides.
In acoustic terms, vowels are sounds that vary in pitch, which –– is determined bythe quality of the sound wave. Pitch is modified by changing the shape of theresonating chamber (the oral and, sometimes, the nasal tracts) by changing theposition and shape of tongue and lips and by lowering or raising the velum.
In functional terms, vowels constitute the nucleus, or necessary, part of the syllable.
Classification of English vowels
For consonants, we must consider four criteria: voicing,orality/nasality, place, and manner of articulation. For vowels, weneed to consider only one criterion: place of articulation.
All vowels are voiced and oral.
In terms of their manner of articulation, all vowels are produced withopen approximation.
Instead of determining which articulators are used and wherestricture occurs, we determine where the highest point of the tongueis during the production of the vowel sound. The position and tensityof the tongue alters the quality of the sound produced.
Another determinig factor is the shape of the lips, which can be moreor less spread (smiling) or more or less rounded (kissing).

Long and short vowels
It depends on whether the vowel is in a stressed or unstressed syllable.
There are short and long vowel pairs suc as /ɪ/ and /i:/
English vowels are tenser than Italian ones.
The schwa /ə/
The most central vowel.
The lips are neither rounded nor spread, the sound is
neither open nor closed, neither front nor back, high or
low, so all articulators involved are in a relaxed or
neutral position.
In Neapolitan /jammə/.
