Systems Involved in Speech Production

Question 1

Respiratory system

Answer 1

provides the driving force behind voice production and other articulated sounds of speech

Question 2

laryngeal system

Answer 2

on top of the trachea; acts as a valve for airway protection, closes like a sphincter during swallowing to prevent aspiration and generating voice with VF or cords when powered by respiratory system

Question 3

Supralaryngeal system

Answer 3

comprises articulators and cavities that filter and shape phonation and glottal aspiration sounds

Question 4

Three major cavities of supralaryngeal system

Answer 4

pharyngeal, oral, and nasal

Question 5

pharynx

Answer 5

(naso, oral, laryngopharynx): tube of tendon and muscle that extends from the base of the skull to behind the larynx where it is continuous with the esophagus

Question 6

Oral cavity

Answer 6

bounded by the palate, the oropharynx and the cheeks and lips

Question 7

velum

Answer 7

consists of soft palate and uvula

Question 8

uvula

Answer 8

fleshy tissue and muscle extension of the soft palate in the back of the throat

Question 9

Elevates velum

Answer 9

paired contraction of the tensor veli palatini and the levator veli palatini and drwas it backward, making contact with the posterior pharyngeal wall

Question 10

Active speech articulators

Answer 10

lower lip, tongue, and glottis which all move during the production of pseech

Question 11

Passive articulators

Answer 11

Remain fixed during speech and are in contact with the active articulators

Question 12

Source filter theory

Answer 12

acoustic theory that describes speech production based on two fundamental processes: sound production and sound filtering
