QUIZ 2 Flashcards
form
form of speech sound- phone
phone- actual production; no meaning attached
function
speech sound function- phoneme
phoneme- smallest unit that distinguishes meaning
what are the basic requirements for meaningful utterances in any language?
form and function
form and function need to work together to signal meaning and be intelligible
why consider phonological theories?
theories:
- are practical
- guide and direct clinical work (assessment and interventions)
- offer a variety of clinical possibilities (different perspectives)
distinctive feature
any property that separates a subset of element from a group
in phonology- create a distinction between the sounds we use in speech
distinctive sound features
demonstrate similarities and disimilarities among phonemes
binary system
(+) indicates PRESENCE of certain features
(-) indicates ABSENCE of certain features
what are the 5 features that establish and distinguish among phonemes? (Chomsky and Halle)
major class features
cavity features
manner of articulation features
source features
prosodic features- WE ARE NOT GOING TO COVER THIS
major class features
sonorant, consonantal, approximants
sonorant
open vocal tract- promoting voicing
vowels, nasals, and approximants
consonantal
sounds produced with a high degree of oral obstruction
plosives, fricatives, affricates, approximants and nasals
approximants
sounds produced with oral obstruction not higher than required for the high vowels [i] and [r]
vowels and approximants
cavity features (place of articulation)
coronal- blade of the tongue raise from its neutral position
anterior- sounds produced in the frontal region of the oral cavity with the alveolar ridge being the posterior border (labial, dental, and alveolar consonants)
nasal- open nasal passageway
lateral- lowered lateral rim portions of the tongue (sound leaving from sides of tongue)
high- high tongue position
low- low tongue position
back- retracted body of the tongue - velar and glottal sounds
rounding- lip rounding [w]
manner of articulation features
continuant- sounds produced without hindering the airstream with any blockages in the oral cavity
[+ continuants]- vowels, fricatives and approximants
[- continuants]- plosives, nasals, and affricates
delayed release- sounds produced with a slow release of a total obstruction within the oral cavity
- affricates
source features
- voiced- produced by simultaneous vf vibration (all vowels are voiced)
- strident- making a loud or harsh sound ( acoustic features of sound)
maximal opposition approach
if we see a lot of speech sounds are missing, we pick 2 phonemes that are very distant from each other (most distinctive from each other)
generative phonology
outgrowth of distinctive feature theory
two levels of sound representation:
1. surface level representations- the actual productions (what the child produced)
2. deep structure- abstract underlying ‘features’ of such production
