ARTICULATORY PHONETICS

Articulatory phonetics is the study of how speech sound are made or articulated. How the articulators interactc to create specific sounds.


The voice is the process through which the voice is produced.
The voice is the result of the action of the larynx.






The sound is the result of the movement of the vocal cords is produced with the passage of air through the glottis. The vocal cords are opened and closed with a wave-like movement. The muscles that control regulating the thickness and strain to produce different frequencies of vibration.
1.      the vocal cords are approximated as a result of muscle contractions that Act on the defined.
2.      air speed increases by effect of the decrease in the opening of the glottis.
3.      the pressure in the glottis decreases and the vocal cords are close: Bernoulli effect + muscle elasticity.
4.      the glottis closes.
5.      subglotica pressure increases.
6.      the vocal cords are separated.




- Voiced and voiceless sounds
We start with the air pushed out by the lungs up through the trachea (or ‘windpipe’) to the larynx. Inside the larynx are your vocal cords, which take two basic positions.
1 When the vocal cords are spread apart, the air from the lungs passes between them unimpeded. Sounds produced in this way are described as voiceless.



2 When the vocal cords are drawn together, the air from the lungs repeatedly pushes them apart as it passes through, creating a vibration effect. Sounds produced in this way are described as voiced.
