English Phonetics and Phonology

Two forms of English
---  written form

For spoken / oral form, it involves the production of speech sounds and the mechanism involved.

Classification of speech sounds
Speech sounds can be classified into two main groups

---  Vowels
---  Consonants

I.  Vowel Speech Sounds (phonemes)
There is no obstruction of airstream in producing vowel speech sounds.

5 features to classify and distinguish the different vowels
    (Refer to the Quadrilateral Chart)

1.  the height of the tongue
     high / mid-high / low

2.  the advancement of the tongue

5.  length of monophthongs
     long / short
                            
II.  Consonant Speech Sounds  (phonemes)
       There is partial or complete obstruction of airstream in producing  
      consonant speech sounds.


        Consonant speech sounds are made either in oral cavity or nasal  
         cavity.
        3 features to classify and distinguish the different consonants

A.  Places of Articulation  (24)
