1. Phonetics: The Sounds of Language
CONSONANT SOUNDS
Deny A. Kwary

2. Three ways of approaching phonetics:
Articulatory Phonetics:
Physiological mechanism of speech production.
Acoustic Phonetics:
The physical properties of sound waves.
Auditory Phonetics:
Perception of the sounds by the brain.

3. Phonetic Transcription
The best-known system:
The International Phonetic Alphabet (IPA)
IPA has been developing since 1888.
The system represents each sound of human speech with a single symbol.
The symbol is enclosed in brackets [ ].

4. Places of Articulation

5. Places of Articulation
Bilabial 
[p], [b], [m]
Labiodental 
[f], [v]
Interdental 
[], []
Alveolar 
[t], [d], [s], [z], [], [r], [n]

6. Places of Articulation
Palatal 
[], [], [t], [d], []
Velar 
[k], [g], [], [w]
Glottal 
[h]
So, how many consonant sounds are there in English Language? 24

7. P. 65, Question #5, a-g [s] : [] [k] : [] [p] : [g] [] : [r]
[m] : [n]
[d] : []
[ f ] : [h]
Alveolar : Alveolar
Velar : Velar
Bilabial : Velar
Bilabial : Alveolar
Palatal : Palatal
Labiodental : Glottal

8. Manner of Articulation
Plosive (Stop): Complete and momentary closure of airflow through the vocal tract.
[p], [t], [k], [b], [d], [g]
Nasal: The airflow passes through the nasal passages.
[n], [m], []
Fricative: Continuous airflow through the mouth.
[f], [], [s], [], [h], [v], [], [z], []

9. Manner of Articulation
Affricate: The stop articulation is released and the tongue moves rapidly away.
[t], [d]
Liquid: Air escapes through the mouth along the lowered sides of the tongue.
[], [r]
Glide: semi-consonants.
[ j ], [w]

10. P. 65, Question #6, a-g [s] : [] [k] : [g] [w] : [ j ] [ f ] : []
[] : [v]
[t] : []
Fricative : Fricative
Stop : Stop
Glide : Glide
Liquid : Stop
Affricate : Fricative
