Define Mental grammar
a system of rules and patterns in the mind that describes a language
= trying to understand what kinds of rules
goal of linguistics
to understand form, acquisition and use of such mental grammars
articulatory phonetics
produce speech sounds
How sounds produced physiologically via apparatus we have
language forms
their physical properties
- in spoken language = sounds, sign language = has same pieces but diff modality
acoustic phonetics
physical properties of sound waves
auditory phonetics
phsyiology of how sounds are perceived
what do sounds consist of
variances in air pressure that stimulate the ear
Ear converts them into signals sent into the brain
where are speech sounds produced in all spoken languages
speech sounds are produced entirely within the respiratory tract - mouth to lungs
how is acoustic quality of sound determined
by manner in which sound is produced
how are sounds produced = components
airflow source (push air in same direction - lungs) —> Vibration (vocal chords) —> filters that change sound quality —> produce diff sounds
human Sounds
lungs —> larynx—> vocal tract —>human sounds
supralaryngeal vocal tract =
nasal cavity
Oral cavity
Pharynx
how are sounds generated
lungs generate air flow - in pulmonic sounds
All sounds made from lungs in English
How are odd sounds generated
(Sounds not in English = glottalic, velaric)
Implosives, clicks, ejectives
Works with air trapped
sound source
vocal folds in larynx
Glottis
opening bewteen vocal folds
Name the 2 basic categories of manipulation that produce sounds
phonation
Articulation
phonation
action of vocal folds as air passes through the glottis
articulation
action by upper articulatory organs = alter path in vocal tract
- modulates sound, otherwise only one noise tone
what contributes greatly to quality of sound produced
action of vocal folds = voiced or voiceless sounds
Voiceless sounds
Vocal folds being relaxed as air passes through glottis
Open glottis, shh
No vocal fold vibration
voiced sounds
prodcued when vocal folds become tense and close together - air flow then pushes the glottis open - as air passes through glottis = vocal folds vibrate - causes air to vibrate at a regular frequency - creating perceptible sound
Buh-duh-zoo
Vocal fold vibration
how do vocal cords vibrate even tho not msucles
Bc Of same mechanisms that allow airplanes to fly
= Bernoulli effect
Bernoulli effect
moving air creates low air pressure
Objects move from areas of high pressure to areas of low pressure
air moves in —> high pressure —> push together then Low pressure air = air moves them apart
Not tensing any msucles or anything - just happens bc of effect of air
