04 - Systems of Speech Production Flashcards
What are the three systems of speech production?
Repiratory System
Laryngeal System
Supralaryngeal System
What is the respiratory system?
(2)
Air Source
Power
What is the Laryngeal System?
(2)
Sound source
Vocal chord vibration
What is the Supralaryngeal System? Where is it?
Sound filter
Above the larynx
What are the parts of the Respiratory System?
(5)
Trachea
Lungs
Rib Cage
Abdomen
Air Passageways
The Respiratory System serves as an “______” in speech production.
Air pump
What is an Eggressive sound?
One made with expiration
What is an Ingressive Sound?
One made with inflowing air
What are the two steps of the Respiratory System?
Inspiration increasing the thoracic cavity volume
Expiration with air released past the vocal cords enabling vibration
What are the parts of the Vocal Tract?
(3)
Pharynx
Mouth
Nose
When the organs in the vocal tract move, the ______ of the vocal tract is ______ forming ________.
Shape
Altered
Various sounds
Where is the Larynx located?
Between the trachea and the hyoid bone
Is the hyoid part of the larynx?
Yes
What is the Glottis?
The space between the true vocal folds
Paired folds meet to ______.
Close the Glottis
Each vocal fold consists of ____ and ______.
Muscle
Vocal ligament
What is the vocal fold muscle called?
Thyroarytnenoid
/θaɪroʊ’ærɪˈtiːnɔɪd/
The vocal folds course from the ______ near the angle and below the ______. They then diverge posteriorly and attach to the ______ of the ______.
Thyroid Cartilage
Thyroid Notch
Vocal Processes
Arytenoids
The Thyroarytenoid muscle has ______ and _____ parts and the latter is the _______ that can vibrate.
External
Internal
Vocalis Muscle
The external thyroarytenoids pull the arytenoids ______ and ______ them.
Forward
Rotate
What are the ventricular folds?
False vocal folds
One glottal cycle constitutes an ______ and _____ of the ______.
Opening
Closing
Glottis
What part of the Glottis opens first?
The middle
How does mechanical coupling stiffness determine the glottal cycle?
It creates the strength of the connection between the upper and lower portions of the mucosal cover of the vocal folds
How does stiffness determine the glottal cycle?
It determines the degree of longitudinal tension of the vocalis muscle
How does mass determine the glottal cycle?
By determing the thickness of the vocalis muscle
How do viscous (gelantinous) forces determine the glottal cycle?
By determining the dissipation of the force applied to the tissue
How does Bernouli Force determine glottal cycles?
It creates the drop in pressure at the medial edge of the vocal folds
What is Bernoulli’s Law?
(2)
Before an event occurs, there is a lot ot potential energy (pressure) but very little kenetic energy (velocity)
After an event occurs, there is a lot of kenetic energy (velocity) but very little potential energy (pressure)
How does age affect the average fundamental frequency?
It drops
How does age affect the length of the vocal folds?
They lengthen
What is the point of the Posterior Cricoarytenoid (PCA) muscle?
(2)
You yank on it to get the vocal folds out of the way
The more width you want, the more you yank
What is the path of the Posterior Cricoarytenoid (PCA) muscle?
Cricoid Cartilige - Posterior Surface
- to -
Arytenoids - Muscular Processes
The Posterior Cricoarytenoid (PCA) muscle is the only intrinsic laryngeal muscles who contraction ______ the vocal folds.
Abducts
(Opens)
