This document provides an overview of phonetics and its subfields. It defines phonetics as the study of sounds and their production in language. The three main subfields are articulatory phonetics, which studies speech production using the organs of speech; acoustic phonetics, which deals with the acoustic aspects of sounds; and auditory phonetics, which concerns the hearing of speech sounds. It then provides details on the organs of speech involved in sound production, such as the lips, teeth, tongue, alveolar ridge, hard palate, velum, uvula, and glottis.

2. Phonetics
-from the greek
word phone meaning

-branch of linguistic
that comprises the study
oof the sounds and their
production.

6. Lips
The upper lip and lower lip help
to produce bilabial sounds
/p, b, m/. If they are held
together, the sounds produced
in that position are bilabial
stops : / p, b/. If the lips are held
together, they produce
different vowels.

8. Teeth
The tip of the tongue helps to
produce /t, d, z, etc/. The
blade of the tongue helps to
produce /t∫, d, ∫, etc/. The
front of the tongue helps to
produce palatal sound /j/
and the back of the tongue
helps to produce /k, g/
sounds.

9. Teeth

10. Tongue
-with its wide variety of
possible movements, it
assists in forming the
sounds of speech.

11. Tongue

12. Alveolar Ridge
-hard ridge behind
upper front teeth. It is
between the roof of
the mouth and the
upper teeth.

13. Alveolar Ridge

14. Hard Palate
-also known as the roof
of the mouth.

15. Hard Palate

16. Velum
The soft palate is
movable, consisting of
muscle fibers sheathed in
mucous membrane. It is
responsible for closing off
the nasal passages during the
act of swallowing, and also
for closing off the airway.

17. Velum(soft palate)

18. Uvula
-the loose hanging end of
the soft palate.

19. Uvula

20. Glottis
- it assist in forming the
buzzing sounds ( g , ng ,j )

21. Glottis

22. Acoustic Phonetics
-Is a subfield
of phonetics which deals
with acoustic aspects
of speech sounds.

23. Auditory Phonetics
Is a subfield of
phonetics concerned
with the hearing of
speech sounds.

24. Phonetic
Transcription
-It is the visual
representation of
speech sounds. The most
common type of
phonetic transcription
uses a phonetic
alphabet is the
International Phonetic
Alphabet
