Exam 1 Flashcards
what does the respiratory system consist of?
lungs, muscles that expand and contract the lungs, air passages connecting the lungs to the atmosphere
what is considered the starting point of the speech production apparatus?
the larynx
what forms the vocal tract?
air passages from the larynx to the oral and nasal outlets
what is the larynx?
a structure of cartilage and muscle connecting the pharynx to the trachea
what are the vocal folds?
two muscle masses that go across the trachea
what is the glottis?
the space between the vocal folds
what is the root of the tongue and what can it do?
the vertical front wall of the pharynx that can move forward, enlarging the pharynx, or backward, constricting it
when the velum is up vs. down what happens?
when up, airflow is blocked from the nasal passage - when down, air flows through it
what is Boyle’s law?
at a constant temperature, lower volume = higher pressure - higher volume = lower pressure - if two spaces are connected, air flows from the space with higher pressure to the one with lower pressure until pressure is equal
how do you inhale?
enlarge the volume of the lungs by contracting the diaphragm and the external intercostal muscles which decreases air pressure in the lungs causing Boyle’s law
how do you exhale?
you squeeze the lungs by the walls of the lungs and the intercostal muscles along the ribs to decrease their volume, increasing pressure in the lungs enacting Boyle’s law
what is the default airflow in speech?
pulmonary egressive airflow (breathing out)
true or false: all spoken languages use egressive airflow for their sounds
false; all languages use it but not for every sound
which sound is made by constricting airflow in the oral cavity?
an obstruent
what is an example of pulsing airflow?
blowing a raspberry/ the Bronx cheer
what is Bernoulli’s effect?
as the rate of airflow is increased, pressure perpendicular to the direction of flow is reduced
what are the steps to making [f]?
the lower lip touches upper teeth, the tongue is low enough to not interfere with airflow, the velum is up, vocal folds are open enough and tense, allowing uninterrupted airflow through the glottis, exhale
what is a fricative?
a sound created by getting uninterrupted airflow through the vocal tract, and then putting an obstacle in the way of it
[f]
Fun
[θ]
THigh
[s]
Sigh
[ʃ]
SHy
[v]
Van
what determines the pitch of a voice?
the frequency of vibration (for men its longer and slower for women its shorter and faster)
[ð]
THy
[z]
Zoo
[ʒ]
aZUre
what are the steps for making [z]?
lips open enough to not constrict airflow, the tip or blade of the tongue is touching the alveolar ridge that airflow is turbulent, velum is up, vocal olds are close and loose enough that they vibrate creating PULSING airflow, exhale
[h]
Happy
why is [h] a unique sounds?
it is the voiceless aspirated version of the following vowel - it is a laryngeal
what is a laryngeal?
a sound without a place of articulation, distinguished only by the state of the vocal folds
true or false: when producing [h], airflow is turbulent
true; it is because the rate of flow is so high not because there is constriction
what is a stop?
a type of obstruent where sound is made with complete closure in the oral cavity, preventing any airflow out of the mouth
what is a plosive?
a type of stop made by building up pressure in the mouth behind a closure, then releasing it suddenly in a burst of turbulent air
what are the steps for creating [b]?
lips are closed, blocking airflow out of the mouth, tongue is down not interfering with airflow, velum is up, vocal folds are close and loose enough to vibrate creating PULSING airflow, exhale, OPEN THE LIPS, allowing pressurized air out
[b]
Buy
[d]
Die
[g]
Guy
what is an aspirated sound and how is it indicated?
produced with the vocal folds tense and spread wide apart at the constant release, allowing max airflow - indicated with [ʰ]
[pʰ]
Pie
[tʰ]
Tie
[kʰ]
Kite
what are the steps for creating [kʰ]?
lips far apart, back of tongue touches velum, velum is up, vocal folds are TENSE AND SPREAD maximally far apart, allowing maximal uninterrupted airflow through the glottis, exhale, lower the tongue and allow pressurized air to rush out
voiceless aspirtated plosives ONLY occur where in English?
at the beginning of a syllable
what is the position of the vocal folds for a voiceless unaspirated sound?
apart and tense enough at consonant release that they don’t vibrate, but not far enough apart to allow maximal airflow
[p]
sPy
[t]
sTy
[k]
sKy
true or false: voiced sounds are never aspirated
true
true or false: a voiceless unaspirated plosive never occurs at the beginning of a syllable in English
true
what is a glottal stop?
the catch in the throat in uH-Oh - it is a voiceless placeless plosive
what are the steps to producing a [ʔ]?
lips are far apart, tongue is low, velum is up, vocal folds are close and tense so that no air can pass through the glottis, exhale, OPEN the vocal folds allowing air to rush out
what is an unreleased stop and how is it indicated?
produced with a closure as in a plosive, but without a release - indicated with [h̚]
[p̚]
toP, caPtor
[t̚]
poT, aTkins
[k̚]
talK, aCtor
[b̚]
laB, aBner
[d̚]
deaD
[ɡ̚]
baG
what are the steps to producing [b̚]?
lips closed, tongue down, velum up, vocal folds are close and loose enough that they vibrate creating PULSING airflow, exhale
unreleased obstruent stops occur ONLY where in English?
at the end of a syllable
a stop at the end of an utterance/before a pause is usually released or unreleased?
unreleased
what is an affricate?
a stop in which air pressure in the oral cavity is released through a passageway so NARROW that airflow through it is turbulent
[t͡ʃ]
CHime
[d͡ʒ]
JIve
what are the steps to making [t͡ʃ]?
lips are far enough apart, blade of the tongue touching alveopalatal region blocking airflow, velum is up, vocal folds far apart and tense enough that they do not vibrate, allowing uninterrupted airflow through the glottis, exhale building pressure, lower tongue blade, but close enough to alveopalatal region that airflow is turbulent
what are sonorants?
sounds produced with airflow that is NOT turbulent - produced by shaping the vocal tract to shape the sound
what is a nasal stop?
sound made by closing the oral cavity, allowing airflow out of the nose
[n]
Nun
what are the steps in making [n]?
lips far apart, tip or blade of tongue touching the alveolar ridge blocking airflow out of the mouth, velum is DOWN, vocal folds are close and loose enough that they vibrate creating PULSING airflow, exhale
