3 components of speech production - Answer 1. respiration
2. phonation
3. articulation
Respiration - Answer -the system of the human body that controls breathing
-thorax, diaphragm, pleura, bronchi, alveoli
-controlled by brain stem, typically involuntary
Upper respiration system - Answer trachea, larynx, and oral and nasal cavities
Lower respiration system - Answer lungs, bronchi, and alveoli
Thorax - Answer -skeleton of the chest
-houses structures of the lower respiratory system
-rib cage (front) and vertebral column (rear)
Diaphragm - Answer -large muscle that contracts and expands with breathing
-forms bottom of thoracic cavity
Pleura - Answer -a thin sac that attached to the inner side of the thorax and the outer side of
the lungs
Bronchi - Answer -air passage per each lung
Alveoli - Answer -small sacs responsible for the exchange of oxygen from the air and carbon
dioxide from the blood
Inspiratory muscles - Answer -primary: quiet and restful breathing (diaphragm and
intercostals)
-secondary: active forced respiration
,Speaking: inhalation to exhalation ratio - Answer 10:90
Breathing: inhalation to exhalation ratio - Answer 40:60
Phonation - Answer -takes energy that is sent upward from the lungs and further modulates
the airflow to convert the energy into sound (pharynx, larynx, trachea)
Pharynx - Answer -a mucosa-lined muscular tube that runs from the nasal cavity, through the
rear of the oral cavity, to the entrance of the larynx and esophagus
3 divisions of the pharynx - Answer 1. nasopharynx
2. oropharynx
3. laryngopharynx
Nasopharynx - Answer -posterior continuation of nasal cavity
Oropharynx - Answer -length of pharynx that connects with oral cavity/throat
Laryngopharynx - Answer -the most inferior portion of the pharynx that opens anterior to
larynx and posterior to esophagus
Larynx - Answer -a cartilaginous box that sits at the front of the neck on top of the trachea
-protects trachea by keeping out everything but air
-contains the vocal folds
Parts of the larynx - Answer -cricoid cartilage
-thyroid cartilage
-arytenoid cartilages
-epiglottis
-extrinsic laryngeal muscles
-intrinsic laryngeal muscles
-hyoid bone
-vocal folds
Cricoid cartilage - Answer -a ring of cartilage that forms the base of the larynx and sits atop
the trachea
, Thyroid cartilage - Answer -largest of laryngeal cartilages that forms the Adam's apple
Arytenoid cartilages (2) - Answer -form anchors for vocal cords
Epiglottis - Answer -protects larynx from unwelcome substances
Extrinsic laryngeal muscles - Answer -keep larynx in midline position while controlling vertical
movements during speaking or swallowing
Intrinsic laryngeal muscles - Answer -control movements of the vocal cords
Hyoid bone - Answer -a horseshoe-shaped bone that floats horizontally at the base of the
neck
Vocal folds (cords) - Answer -close tightly to protect trachea and lungs from foreign matter
Voice - Answer -the creation of sound by vocal fold vibration
Trachea - Answer -the cartilaginous tube that runs from the oral cavity down to the lungs,
where it separates into 2 bronchi
-principle function: transport air between environment and lungs
Respiratory system and speech - Answer -pharynx, larynx, and trachea form pathway for
energy supply of speech
-vocal cords turn airflow into voice through vibrations
-pharynx provides a resonating chamber for airflow
Resonance - Answer -the ongoing vibration of air as it moves through the pharyngeal tract
Articulation - Answer -further modulates the column of air that is channeled through the
phonatory system
-the act of manipulating the airflow submitted by the phonatory system to create highly precise
speech sounds
-American English: 40 phonemes
Chief articulators - Answer -maxilla and mandible
