Lecture 5 Flashcards
Suprasegmental properties
properties that span over multiple speech sounds
ex: stressed syllables, intonation (prosody), tone (differences in pitch that connote differences in meaning), lexical tone (Mandarin: where pitch changes the meaning)
Phonotactics
is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes.
phoneme
any of the perceptually distinct units of sound in a specified language that distinguish one word from another, for example p, b, d, and t in the English words pad, pat, bad, and bat.
reflexive vocalizations
cooing
2-4 mos
canonical babbling
deaf babies?
6 mos +
reduplicated or variegated babbling
not done by deaf babies - - influenced by hearing
hearing babies: range of consonants increases
deaf babies exposed to sign language – hand babble
reduplicated babbling
duplicating the same syllable
wagging the jaw or tongue: babababa
variegated babbling
multiple syllables
(bapitugolati)
kids mixing up the sounds they’re producing
becomes more frequent by 12 months
jargon stage
10 months+
meaningless but conversational - EYE CONTACT, gesture, adult prosody
AKA “modulated babble”
classifying sounds: particular features
is it a consonent (stopping the airstream or slowing it down) or a vowel
Children’s Speech errors are..
… fairly systematic if you think in terms of descriptive features
(IPA - international phonetic alphabet, not spelling)
Producing sound
vocal tract diagram
produce R’s and L’s as W’s
Vocal tract diagram is sort of like a thumb over water hose
thumb = mouth
water stream = air stream
source of flow (water spigot, vocal folds)
stopper at the top (thumb, lips/tongue)
except the stopper has a lot of “settings”
- resonating
- stopping completely
- leaking
- pinching
fricative sound
where you’re pinching most of the airstream off but there’s still a very concentrated stream of air coming out
pinching: letting a turbulent airstream out
ex: sssssss,zzzz
Vowels and producing sound
allow all the sound to come out - unobstructed airstream
stopping sound completely is called?
stop consonant
kids mostly produce stop consonants
much easier to closed-open-closed-open movement
Obstruent Consonants
stops, fricatives, affricates
