Speech Science, Measuring Airflow and Respiratory function

if tension of the vocal folds increases, what will happen to the fundamental frequency of a person's voice?

increase

what does subglottal pressure do as intensity increases?

increases

is a pneumotach a DIRECT or INDIRECT way to measure airflow?

indirect

what is a pneumotachograph used to measure?

intraoral pressure

if a patient has Spasmodic Dysphonia, how will the duration of their airflow be different than a normal speaker?

it will be shorter

if a person's voice sounds breathy, what does that indicate about their airflow?

it's higher in volume and flowing for a shorter period of time

if a person's voice sounds strained, what does that indicate about their airflow?

it's lower in volume and flowing for a longer period of time

which muscles change medial compression?

lateral cricoarytenoids and interarytenoids

name the intrinsic muscles of the Larynx

lateral cricoarytenoids, interaryntenoids, thyroarytenoids (thyromuscularis and thyrovocalis)

what is the definition of airflow?

movement of a quantity of gas through a given area in a unit of time

which muscles change subglottal pressure?

muscles of inhalation and exhalation

if a person has vocal fold paralysis, which branch of the Vagus nerve was likely damaged?

recurrent laryngeal branch

What can measurements of flow provide information about?

respiration, phonation, articulation

describe the airflow during a fricative

slow and low intensity

what is definition of volume in reference to airflow

the built-up quantity of air over a period of time

which muscles are used to decrease tension in the vocal folds?

thyroarytenoids (unopposed)

which muscles are used to increase tension of the vocal folds?

cricothyroids

what is the range of 'normal' airflow (mL/sec)?

75-250 mL/sec

what is a U-tube manometer used to measure?

alveolar pressure

what causes 'resistance' in reference to Ohm's law

amount of medial compression of the vocal folds

describe the airflow during a voiceless stop

completely stopped during stop-gap and then high intensity flow during the burst-release

if a person is unable to completely close their lips, which cranial nerve was likely damaged?

facial nerve, CN VII

Ohm's law

flow = pressure / resistance

how can subglottal pressure be INDIRECTLY measured?

with a speech-task that measures intraoral pressure during a voiceless stop-gap (active cessation)
