Transcript of HUMAN SPEECH APPARATUS

speech production
the process by which spoken words are selected to be produced, have their phonetics formulated and then finally are articulated by the motor system in the vocal apparatus.
HUMAN SPEECH APPARATUS
- a large air filled space above and behind the nose in the middle of the face.
- it helps to produce the three consonants:
m
,
n
,
ng
.
Alveolar ridge
-is between the top front teeth and the hard palate. You can feel its shape with your tongue.
-Sounds made with the tongue touching here (such as
t
and
d
) are called
alveolar
.
teeth
pharynx
- is a 5 inch long conical, fibromuscular cavity within the throat that is situated posterior to the nasal and oral cavities and posterior to the larynx.
- its function for speech is its presence. Without it, no air will pass through then to the larynx to vibrate. No vibration in vocal chords, no production of sounds.
vocal cords
- it represents the chief mechanism of the larynx in its function as a valve for opening the airway for breathing and to close it during swallowing.
-vocal cords is the source for speech production in humans. It generates two kinds of speech sounds these are
voiced and unvoiced.
The vibration of vocal cords produces the sound called the voicing and the unvoiced sound due to turbulence of flow of air at a constriction at all possible sites in the vocal tract.

palate
- allows air to pass through the nose and through the mouth. Oftenly in speech it is raised so that air cannot escape through the nose.

- it is one of the articulators that can be touched by the tongue. When we make the sounds
k
and
g
the tongue is in contact with the lower side of the palate, and we call these
velar consonants
.
NASAL CAVITY
uvula
this phonological function of uvula is very important as proper speech depends on it. Hence, one must know that this part of the body does its job really well and helps us in eating well as well as in speaking properly. Without proper functioning of this, speech would have been nasal and the person has a
tough time pronouncing consonants
.
lips
-They can be pressed together (when we produce the sounds
p
,
b
),
- can brought into contact with the teeth (as in
f
,
v
)
-or rounded to produce the lip-shape for vowels like

.
-Sounds in which the lips are in
contact with each other are called bilabial
, while those with
lip-to-teeth contact are called labiodental.


tounge
The tongue is able to produce incredibly fine and complex movements, by either directing the breath stream during consonant production or elevating and lowering to form a resonance vessel for vowel sounds.
larynx
- is a 5 inch long conical, fibromuscular cavity within the throat that is situated posterior to the nasal and oral cavities and posterior to the larynx.
- its function for speech is its presence. Without it, no air will pass through then to the larynx to vibrate. No vibration in vocal chords, no production of sounds.
epiglotis
-is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx.

The epiglottis functions as an articulator in the production of pharyngeal consonants and in the vowel. It is also
involved in whisper.
In whisper, the epiglottis is generally more retracted than in normal speech but otherwise moves as usual. This article concludes that the epiglottis is an active, independent, and acoustically significant articulator.
- is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart.
-Speech requires some sort of air source. We produce a majority of speech sounds by forcing air upwards from the lungs, an action that is used in normal breathing.
- The diaphragm regulates efficient oxygen delivery and carbon dioxide elimination. It is the muscle that separates the thoracic cavity from the abdomen.
- Maintain a steady pressure of air as you talk.
Let's have some little refreshments!
can you give atleast five Human Speech Apparatus?
That's Great!
Here's your prize :)
what kind of consonant is
k
and
g
?
evrla oactnsnon
thumbs up! :)
here's your prize :)
what is the difference between
bilabial
&
labiodental
?
i Muy bien !
here's your pretty little prize :)
we hope you enjoyed it and

learned something new

thank you ! :)
