The organs of speech

labiodental (the obstruction is formed by the lower lip being pressed against the upper teeth):

[f], [v]

c) forelingual (the obstruction is formed by the front part of the tongue):

[Ө], [ð], [t], [d], [l], [s], [z], [  ], [ ], [t ], [ ]

d) mediolingual ( the front of the tongue is raised to the hard palate):

[j]

e) backlingual (the back of the tongue is raised to the soft palate):

[k], [g], [ŋ]

f) glottal (the place of obstruction is the pharynx):

[h]

2. 
   According to the manner of the production of noise, consonants are divided into:
   

1. 
   occlusive (in making occlusive consonants the active organs of speech form a complete obstruction).They are subdivided:
   

1. 
   plosives (a kind of explosion is heard)
   

[b], [p], [d], [t], [k], [g]

2) occlusive sonants

[m], [n], [ŋ]

b) constrictive consonants (in making them the active organs form a narrowing of the air passage). They are subdivided into:

1. fricative [f], [v], [Ө], [ð], [h], [s], [z], [  ], [ ]

2. constrictive sonants [j], [l], [v], [r]

c) affricates (in pronouncing these sounds the articulating organs form a complete obstruction at first and then they are slowly released forming a narrow air passage).

[ t ], [ ]

3. 
   According to the work of vocal chords, consonants are divided into voiced and voiceless.
