Speech articulators

Speech articulators

1. is divided into three sub-sections

   • is divided into three sub-sections
   • SUB-LARYNGEAL
     • D) THE LUNGS power the movement of the air (pulmonic airstream mechanism)
       • B) THE DIAPHRAGM causes the enlargemt of the lungs so that the air pressure goes down and then the air rushes from outside the body to equalize the difference.
         • THE TRACHEA is a tube that connects the lungs and mouth.
   • LARYNGEAL
     • THE LARYNX is made up of he cricoid, thyroid and arytenoid cartilages, along with the vocal folds and the muscles that connect them. They all together control the pitch and voicing.
       • C) THE EPIGLOTTIS, in colaboration with the larynx, allows the swallowing.
         • E) THE PHARYNX is behind the tongue, is an open space that allows greater freedom for the movement of the tongue.
   • SUPRA LARYNGEAL
     • Active Articulators
       • LOWER LIP: Both lips move to some degree but the lower lip moves more in speech.
         • TONGUE: Is an all mucles organ (muscular hydrostat), this organ has three parts that are active in speech as they move relatively independently: tongue front, body and root.
     • Passive Articulators
       • UPPER LIP H) UPPER TEETH A) ALVEOLAR RIDGE HARD PALATE UVULA PHARYNGEAL WALL
         • G) THE VELUM has a dual status, it serves as a passive articulator when the tongue body moves and it regulates the airflow between the oral and nasal tract by going up or down.
           • F) NASAL CAVITY determines the particular quality of an individual voice.
