ASLP 3030 Exam 2025 Questions and
Answers
1. What is a U-tube manometer and what does it measure? - --CORRECT
ANSWER--measures the amount of force.
in speech we use cmH20 this is used to measure the force required to move water.
During speech research we can measure things using water columns. The person
blows into the column and pushes the water from 0 (pressure to be
measured)down the column at 6cm. (atmospheric pressure) Not good way to
measure speech because different sounds require different amounts of force.
1. How does intraoral air pressure differ for a stop and/or fricative consonant vs. a
vowel consonant? Which sound has intraoral pressure that is roughly equal to
atmospheric pressure? - --CORRECT ANSWER--Vowel consonant has intraoral
pressure that is roughly equal to atmospheric pressure because the mouth is wide
open so the pressure inside the mouth is the same as the outside.
the pressure for fricatives is elevated intraoral pressure because you have to build
up pressure for sounds like /s/ /z/

, With Stops the intra oral pressure is the highest because you need to have greater
pressure to develop sounds like /p/ and /t/
What is subglottal pressure? - --CORRECT ANSWER--pressure below the vocal
folds
Which sound has intraoral pressure that is roughly equal to subglottal pressure? - --
CORRECT ANSWER--voiceless bilabial /p/
because when you do a voiceless sound you have to keep lips closed and generate
pressure behind lips but still have to leave your VF open
What value of subglottal pressure is normal when speaking at a typical,
conversational volume? - --CORRECT ANSWER--5-7 cm h2o typical for normal
speech
15-20 comH20 for loud speech
What is phonation threshold pressure? - --CORRECT ANSWER--amount of
pressure required from to lungs in order to get the vf to oscililate. very softest a
person can produce
Why would phonation threshold pressure be higher in speakers with voice
disorders? - --CORRECT ANSWER--scaring or pathologies in mucosa
(jelly/fluffy roll w air)they will not have that consistency and require more air
pressure to get them moving
