Cours 2 : Phonetics and Phonology Flashcards
definition of phonetics
study of sounds in human language
definition of phonology
study of the pattern of phonemes and relationships between the phonemes of a language
3 systems of speech production in phonemes (human sounds go through 3 systems)
- respiratory system : produces the airstream needed for speaking
- phonatory system : produces voice
- articulatory system : responsible for the variations and articulations
function of the vocal tract
it gives the vibration and shaping of the speech
function of the larynx
it works like a resonating chamber
the tenser the cords, the higher the pitch
function of the mouth
it produces sound : the active articulators move towards the passive ones and modify the airstream
articulation : the criteria to classify sounds
articulation indicates which active articulator will create constriction.
3 parameters :
1. place of articulation
2. manner of articulation
3. energy of articulation
places of articulation
- bilabial
- labio-dental
- dental
- alveolar
- palato-alveolar
- palatal
- velar
- glottal
what is the McGurk effect ?
what we hear is influenced by what we read on other people’s lips
other articulators
> uvula
tongue
glottis (not in the articulatory system)
manner of articulation
sounds are produced through scrictures. there are 3 different kinds of scrictures :
- complete closure
- close approximation
- open approximation
complete closure (manner of articulation)
when we block the airstream in the mouth
> stops : the airstream is blocked
nasals : the oral cavity is closed but the soft palate is lowered to let air escape through the nose.
close approximation (manner of articulation)
fricatives : the articulators are close, but they don’t make a complete closure.
obstruents (provoke obstruction) and sonorants
open approximation
approximants : articulators come close, but not close enough to produce friction
lateral sounds : closure at the centre but the air can escape via the sides of the tongue
semi-vowels/semi-consonants
energy of articulation
lenis = voiced : vocal folds vibrate
fortis = voiceless : vocal folds don’t vibrate
classification of vowels
tongue shape
lip shape
duration
constancy of tongue shape and lip shape
position of velum
tongue shape
how close the tongue is to the roof of the mouth
> /i/ is close to the roof
/a/ is far from the roof
> front vowel : the front of the tongue is highest (/i/)
back vowel : the back of the tongue is highest (/uh/)
lip shape
rounding the lips deepens the pitch and increases resonance
front and open vowels have spread/neutral lips, back vowels have rounded lips
duration
time taken for a sound to be pronounced
checked vowels are shorter than free vowels (“pip” VS “peep”)
constancy of tongue
if the position of the lips remains steady, steady-state vowels = monopthong
if there is a change, vowel glide = diphtong
position of velum (= soft palate)
nasal vowels are produced with the velum lowered
phonology
the analysis of the cognitive organisation of the sounds in the brain. il allows a speaker to form meaningful combinations of words
phonemes
abstract mental units : what our brain thinks about when we make a sound. it’s also the smallest unit that distinguishes meaing between words in a language
phone
a set of speech sounds that are seen as equivalent
> “Pull”/”sPin”/”toP”
allophone : the same phoneme has different realisations
