The Production Speech Sounds

The Production Speech Sounds

1. Speech starts in the brain, and it is, then, studied by Psycholinguistics.

2. We need a representation of the sound sequence and a number of commands.

   • Phonetic plan of and a motor plan.

3. The process

   • Speech is produced by an air stream from the lungs, which goes through the trachea and the oral and nasal cavities.
     • Four processes:
       • *Initiation. *Phonation. *Oro-nasal. *Articulation.
   • The air is expelled from the lungs.
     • The phonation process occurs in the larynx through the glottis.
       • The glottis can be closed. Then, no air can pass.
       • The glottis can have a narrow opening which can make the vocal folds vibrate producing the “voiced sounds”.
       • The glottis can be completely open producing the “voiceless sounds”.
   • After it has gone through the larynx and the pharynx.
     • The velum is the part responsible for that selection.
   • The articulation process
     • It takes place in the mouth.
       • The oral cavity, which acts as a resonator.
     • Can be active or passive.
       • We can find to the upper and lower lips, upper and lower teeth, tongue and roof of the mouth.
