Chapter 11 Flashcards
Definition of voice
the complex, dynamic product of vocal fold vibration that allows us to vocalize and verbalize
Definition of vocalize
to make sounds
Definition of verbalization
to produce language through speech
Definition of adduction state
when the the vocal folds must be closed, or adducted, at midline
Definition of abduction
when not producing voice, the vocal folds rest in an open, or abducted, position so that one can breathe
what has to happen for phonation to occur?
air is exhaled from the respiratory system upward against the adducted vocal folds, which are then blown apart and vibrate
Definition of resonation
actual air vibration within the pharyngeal column, which impacts the quality of the voice
Definition of articulation
when the voice is manipulated within the oral cavity
Definition of frequency
the rate of vocal fold vibration, expressed in cycles per second, or hertz
Frequency is an _____, _____ measurement of vibratory rate
objective, physical
Pitch is the ____ equivalent to frequency
perceptual
Definition of Fundamental frequency
the arithmetic mean of the rates of vibration for the vocal folds
if an individual’s vocal folds vibrate 250 times in a second, what is the fundamental frequency?
FO is 250 Hz
a person’s fundamental frequency relates to what three characteristics of the vocal folds?
length
mass
tension
effect of length of vocal folds
Longer vocal folds contribute to a lower FO
effect of mass of vocal folds
Thicker vocal fold mass contributes to a lower FO
Definition of tension of vocal folds
Greater tension contributes to a higher FO
true or false: the greatest amount of change occurs between birth and puberty
true
when does fundamental frequency decreases most significantly for males?
puberty
when does fundamental frequency decreases most significantly for females?
midlife
Definition of Intensity
the physical measurement of sound pressure reported in decibels (dB), which corresponds to the perception of loudness
What two features of vocal production does loudness relate to?
the amount of airflow from the lungs
the amount of resistance of the airflow by the vocal folds
true or false: an increase in airflow from the lungs is the only way to result in increased loudness
false: increased resistance – achieved through compression of the vocal folds at the midline also increases in loudness
Definition of phonatory quality
how well the two vocal folds work during the vibratory cycle
