Ch. 25 Sound Production In Speech Flashcards
Lungs
Form a passive air reservoir
Diaphragm
Muscular structure at the bottom of the chest cavity used to control pressure in the chest cavity surrounding the lungs.
Trachea
Carries air between the lungs and the pharynx.
Larynx
Structure of cartilage at the upper end of the trachea containing the vocal folds.
Esophagus
Transports materials from the pharynx to the stomach.
Epiglottis
Cartilage flap used to cover the trachea opening (to swallow)
Pharynx
Forms the lower part of the vocal tract, connecting the mouth and nasal cavity to the trachea.
Voice energy
By using the vibrating vocal folds to interrupt the airstream in a periodic manner
Noise energy
By forming a constriction in the vocal tract causing the airstream to become turbulent and noisy as it flows through the construction
Burst energy
Completely closing off the vocal tract thus stopping the airflow, and then releasing the air pressure suddenly
Glottis
The opening between the vocal folds
Thyroid cartilage
Cartilage at the front of the larynx that the vocal folds are attached to
Adam’s apple
Arytenoid cartilage
cartilage that the vocal folds are attached to at the back of the lyrics
What two primary variable serve to control the vibration frequency of the vocal folds
Stiffness and mass
Glottal airflow
The volume of air flowing through the glottis per unit of time
