4. SPEECH ORGANS AND
ARTICULATION
There are seven main articulators;
1. Pharynx
2. Velum/Soft Palate
3. Hard Palate
4. Alveolar Ridge
5. Upper Teeth
6. Lower Teeth
7. Lips
5. Manners of Articulation
• Plosive / stop
air flow momentarily halted, then /p/ /b/ /g/
released forcefully
• Fricative
friction is caused by a slight /f/ /z/
obstruction in the air stream
• Affricate
a mixture between plosive and
/t /
fricative; the air flow is first
halted, then released with friction /d3/
6. Manners of Articulation
• Lateral
formed by the sides of the tongue /l/
making contact with the upper teeth
• Post-alveolar or retroflex /r/
tongue bent upwards and backwards
• Nasal
/m/ /n/ /y/
air release through the nasal
passage
• Glides/Frictionless continuant /w/ /r/ /j/
no friction, but lasting sound

9. Voice production..
• organs of speech - in the mouth and throat.
• air pushed out from the lungs through the
larynx and epiglottis vibrates the vocal cords-
• producing a continuous tone whose pitch can
be changed by varying the shape of the larynx.
• Consonants - modified by the tongue and lips,
are formed when air is emitted suddenly or when
it is cut off firmly.
• Voice production occurs in the larynx.
10. • During breathing the vocal cords are held
apart, but as speech commences, the
cartilages of the larynx are drawn together by
the action of muscles and a "chink" is created.
• The tension of the vibrating cords, changed
by the tilting of the cartilages, alters the pitch
of the spoken sound. High notes are produced
by the vibration of tight vocal cords and low
notes are produced by vibrating loose cords.
Chink - a small narrow crack or opening
12. Velum/Soft Palate
• Velar consonant.
• Often in speech, the velum is raised so that air
cannot escape through the nose.
• When the /k/ and the /g/ (velar consonants)
sound is produced, the tongue is in contact
with the lower side of the velum.
13. HardPalate
Hard Palate
• Roof of the mouth.
• interaction between

formation of /t/, /d/ and /j/ sound.
14. Alveolar Ridge
• Alveolar sound.
• Between the top front teeth and the hard
palate.
• It’s surface is covered with little ridge.
• The sound produced is called alveolar
– /t/ and /d/
15. Teeth (Upper and Lower)
• Most speakers have teeth to the sides of their
mouth.
• The back is almost to the soft palate.
• The tongue is in contact for many speech
sounds.
• Dental sound;
/t/, /d/, /n/, and /l/
16. Lips
• Pressed together (bilabial)
/p/
• Brought into contact with teeth (labiodentals)
/f/, /v/
• Rounded
/u/
17. Larynx (Adam’s apple)
• A very complex and dependent articulators
• The vibration of larynx can be detected while
producing the sound /z/
19. Jaws
• Being called as articulators because of the
movement of the jaws
• Jaws not like other articulators – don’t make
contact with other articulators.
