SLHS2203: physiology of articulation and resonance

power

the expiratory airflow from the lungs tthat generates the power source for voicing

source

the larynx; houses the vocal folds and is responsible for vocal fold vibration

filter

structures above the vocal folds that shape the sound; resonators

place

where the sound is produced in the vocal tract

manner

how the sound is produced based on interactions between articulators

voicing

whether the vocal folds vibrate during sound production

bilabial

consonant sound formed by both lips touching (/m/)

labiodental

consonant sound formed by the lips and teeth touching (/f/)

interdental

consonant sound formed by the tongue being placed between the teeth (/θ/ or th)

alveolar

consonant sound formed by the tongue touching the alveolar ridge (/l/)

post-alveolar

consonant sound formed by the tongue touching slightly behind the alveolar ridge (/tʃ/ or ch)

palatal

consonant sound formed by the tongue touching the hard palate (/j/)

velar

consonant sound formed by the tongue touching the velum

glottal

consonant sound formed in the throat (/h/)

stops/plosives

airflow is stopped and then released in a burst

nasals

sound is produced through the nose

affricates

combination of a frictive and a stop

frictaves

air escapes through a narrow passge, creating a very noisy sound

voiced sounds

vocal folds vibrate

voiceless sounds

vocal folds dont vibrate

diphthongs

combination of two vowels

DIVA Model

Directions Into Velocities of Articulators; multi-system coordination for perception and production of speech

speech sound disorders

functional (no known cause) or organic (acquired or developmental)

hypernasality

too much nasalization

hyponasality

not enough nasalization

cul-de-sac resonance

sound is trapped in the cavity of which it’s produced
