This document discusses how voice is produced for speech. It explains that sound is generated by the vocal cords vibrating when air is pushed out from the lungs during exhalation. This sound then resonates as it passes through cavities in the throat, nose, and mouth before being articulated into speech sounds using the tongue, palates, teeth, and lips.

1. A twister of Twist
Once Twisted a Twist
And the Twist that he
Twisted was a twisted twist.
Now, in twisting this twist
f the twist should untwist
The twist that untwisted
Would untwist the twist.

2. HOW VOICE IS
PRODUCED?

3. Speaking is our ability to form
sounds and to use them to
communicate abstract ideas and
feelings. We do not have a
specialized system in the same
was that we have our digestive
and respiratory system.

4. To produce speech, the lungs, the
mouth and the throat and other
part of the body coordinate to
generate sound, resonate sound
and articulate sound.

5. The primary generators of soud
are the vocal cords which are the
muscles that make up the larynx.
Sound is generated by pushing
out air in such a way that the
vocal cords vibrate.

7. The respiration cycle consisting
of the inhalation and exhalation
of air from the lungs plays a part
in generating speech.

8. Before sound produced by
exhaling air can be speech, it
must be given resonance or
reinforcement produced by
vibration.

9. The resonators of sound of
speech are:
--the bones in the chest, neck,
and head
-- the cavities of the throat, nose
and mouth

10. Most resonance occurs in the
cavity.
A cavity is a partially enclosed
area. Every cavity has a natural
range of sounds depending on:
--size
--shape
--texture of its composition
--the size pf its opening

11. TYPES OF CAVITY
1.PHARYNGEAL CAVITY
(THROAT)
2.NASAL CAVITY (NOSE)
3.ORAL CAVITY (MOUTH)

12. ARTICULATION
It is the shaping of speech sounds
into recognizable oral symbols
that go together to make up a
word. Most communication. Most
communication problems are
caused by poor articulation

13. MAJOR ARTICULATORS OF
SOUND IN THE MOUTH
1. The tongue
2. The hard and soft palates
3. The teeth
4. The lips
