Outline Definition Classification Description Phonemes and Allophones Transcription Allophonic rules
definitionConsonant sounds are the sounds in the production of which two articulators come together so that the airstream is obstructed and can not get out freely.
eg. /p, k, s, t, j/
Speech organs (articulators)
classification24 English consonants are classified according to 3 criteria: Place of articulation Manner of articulation Voicing
place of articulation1. Bilabial (upper lip+lower lip) /b, p, m, w/ 2. Labiodental (lower lip+upper teeth) /v, f/ 3. Dental (tongue+teeth) /D, T/ 4. Alveolar (alveolar ridge+tongue) /d, t, z, s, l, n/
place of articulation5. Palato-alveolar (hard palate+alveolar ridge+tongue) /Z, S, dZ, tS, r/ 6. Palatal (hard palate+tongue) /j/ 7. Velar (soft palate+tongue) /g, k, / 8. Glottal (vocal cords) /h/
manner of articulation1. Plosive (complete closure+sudden release) /b, p, d, t, g, k/ 2. Fricative (narrowing resulting in audible friction) /v, f, z, s, Z, h, D, T, S/ 3. Affricate (closure+low separation) /dZ, tS/
manner of articulation4. Nasal (complete closure+air escape through nose) /m, n, / 5. Lateral (closure in mouth centre+air escape at tongue sides) /l/ 6. Approximant (slight narrowing but not enough to cause friction) /w, j, r/

FULL VOICED
THREE STAGES OF PLOSIVES Closing stage: articulating organs move together to form obstruction Compression stage: air compressed behind closure Release stage: compressed air escapes abruptly
description of bilabial plosivessoft palate raised, nasal resonator shut off, closure by lips
lung air compressed vocal folds wide apart: /p/ vocal folds vibrating: /b/
lip closure released, air escaped
/p, b/
description of alveolar plosivessoft palate raised, nasal resonator shut off, closure by tip and rims of tongue, upper alveolar ridge and side teeth
lung air compressed vocal folds wide apart: /t/ vocal folds vibrating: /d/
alveolar closure suddenly separated, air escaped
/t, d/
description of velar plosivessoft palate raised, nasal resonator shut off closure by back of tongue and soft palate
lung air compressed vocal folds wide apart: /k/ vocal folds vibrating: /g/
linguo-velar closure suddenly separated, air escaped
/k, g/
description of glottal plosivevocal folds closed silence no vibration of vocal cords vocal folds suddenly separated, air pressure below glottis released eg. Its empty. / /

FULL VOICED
description of labiodental fricativessoft palate raised, nasal resonator shut off closure by inner surface of lower lip and edge of upper teeth
lung air compressed, friction voiceless: /f/ voiced: /v/
air released
/f, v/
description of dental fricativessoft palate raised, nasal resonator shut off closure by tip and rims of tongue and edge, inner surface of upper front teeth and upper side teeth
air causes friction voiceless: / T / voiced: /D/
air released
/T,
description of alveolar fricativessoft palate raised, nasal resonator shut off closure by blade of tongue and upper alveolar ridge, side rims of tongue and upper side teeth
air causes friction between tongue and alveolar ridge voiceless: /s/; voiced: /z/
air released
/s, z/
description of palato-alveolar fricativessoft palate raised, nasal resonator shut off closure by tip and blade of tongue and alveolar ridge, side rims of tongue and upper side teeth front of tongue raised
friction between extensive area of tongue and roof of mouth voiceless: /S/; voiced: /Z/ air released
/S,
description of glottal fricative /h/ Only in syllable-initial, prevocalic positions Voiceless
no closure
air expelled from lung with considerable pressure
friction throughout vocal tract
features of affricates
beginning as plosives but ending as fricatives the plosive and the fricative being homorganic eg. church /tS : tS/ (but breakfast)
description of palato-alveolar affricatessoft palate raised, nasal resonator shut off, closure by tip, blade and rims of tongue, upper alveolar ridge and side teeth front of tongue raised
closure released slowly, friction between blade of tongue and alveolar palatal of roof of mouth voiceless /tS/; voiced /dZ/
/tS,
nasals
Features Description
features of nasals
Total closure within the mouth at some point, air escaped into nasal cavity No audible friction is produced nasals are voiced
description of bilabial nasallips closed, mouth chamber closed, soft palate lowered
resonance of nasal cavity added to those of pharynx
air released
/ m/
description of alveolar nasalclosure by tongue, tip ridge and upper side teeth, soft palate lowered
resonance of nasal cavity added to those of pharynx and that part of mouth chamber
air released
/n/
description of velar nasalclosure by back of tongue and velum, soft palate lowered
resonance of nasal cavity added to those of pharynx and that part of mouth chamber
air released * Only after /I, e, {, , /

description of lateral /l/Clear /l/ & Dark /l/soft palate raised, nasal resonators shut off, closure by tip of tongue and upper teeth ridge
air escaped on both sides
CLEAR /l/before vowel and /j/: look front of tongue raised towards hard palate, front vowel resonance
DARK /l/other positions: feel front of tongue depressed, back raised towards soft palate, back vowel resonance
approximants
Palato-alveolar approximant /r/ Bilabial approximant /w/ Palatal approximant /j/
description of palato-alveolar approximant soft palate raised, nasal resonator shut off, tip of tongue held near to but not touching rear part of upper teeth ridge, central part of tongue lowered
airstream escapes without friction
/r/
description of bilabial approximant /w/soft palate raised, vocal folds vibrate tongue in position for back close-mid to close vowel, moving away immediately to position of following sound
eg. weather. which, twin
description of palatal approximant /j/tongue in position for close-mid to close vowel front, moving away immediately to position of following sound
eg. yawn, senior, use
Phonemes & allophones
PHONEMES Definition the smallest segment of sound that can distinguish two words ideal object Features abstract limited (44)
ALLOPHONES different realisations of the same phoneme
physical manifestations real and concrete unlimited
Difference between Difference between phonemes is functional allophones is phonetic difference. Example cat & bat cat & cot difference. speak & pick note & teeth
