Phonology Flashcards
Phonology
Study of the sounds used in speech including how they are produced
The 4 Phonological stages of development
- Vegetative (0-4 months)
- Cooing (4-7 months)
- Babbling (6-12) (slight overlap)
- Proto-words (9-12) (babbling overlap)
Vegetative stage
Features: Sounds of discomfort/reflexive actions
Examples: Crying, Coughing, Burping, Sucking
Cooing stage
Features: Comfort sounds and vocal play using open mouthed vowel sounds
Examples: Grunts+Sighs become like ‘coos’, Laughter, Hard consonants and vowels, Pitch (squeals and growls) and loudness (yells) practised
Babbling stage (6-12)
Features: Repeated patterns of consonant and vowel sounds
Examples: Sounds linking to own language, Reduplicated sounds (ba-ba), Non-reduplicated sounds (variegated) e.g. agu
Proto-words/Holophrases
Features: Word-like vocalisations, Not matching actual words but used consistently for the same meaning (‘scribble talk’)
Examples: ‘mmm’ to mean ‘give me that’ with accompanying gestures supporting the verbal message e.g. pointing
Consonant (pre-verbal stage)
A speech sound that is produced when the vocal tract is either blocked or so restricted that there is audible friction
Vowel (pre-verbal stage)
A sound made without closure or audible friction
Production of Sound
- Sounds are produced by air from the lungs passing across the vocal cords.
The production of consonant sounds is affected by: - The Manner of articulating (how the air-stream is controlled)
- The Place of articulation (where it occurs) (lips, tongue, teeth, the roof of our mouth or combination
- Whether sound is voiced or unvoiced (vibrating or not vibrating the vocal cords)
Phonemic expansion
When the variety of sounds a child produces increases
Phonemic contraction
When the variety of sounds a child produces reduces to the sound they need for their own language
Why is producing sounds crucial for child development?
Attention
Basic survival and emotional needs
Cooing/Babbling (marks start of prosodic features)
Pitch and tone encode meaning for listener/receiver of a verbal message
- This links to pragmatics development as prosody is important for social interaction
Intonation importance
- Gives listener clues to meaning of speaker’s message
- Use of pitch to signal feelings (rising pitch e.g. excitement)
- Pitch can give listener notice we are giving up our turn to speak (rising intonation e.g. question)
The 2 Vowels
- Monophthong
- Diphthong
Monophthong
- Produced when a vowel is followed by one or more consonants in a syllable
In IPA obvs
Short: ‘ae’(apple), ‘a’(hot), ‘I’(tip)
Long: ‘e’(me), ‘u’(chew), ‘au’ (author), /3/ ‘or’ work
Diphthong
- Produced by combining 2 vowels in a single syllable where the sound begins as one vowel and moves towards another
In IPA obvs
Short: ‘ei’(tape), ‘ai’(ice), ‘u’(cube)
Long: ‘oy’(boy), ‘ou’(mouth), ‘eer’(deer)
The 6 consonant Phonemes
- Plosives
- Fricatives
- Affricates
- Approximants
- Nasals
- Laterals
Plosives
When the airflow is blocked for a brief time (‘stop consonants’)
Voiced: b, d, g
Unvoiced: p, t, k
Fricatives
When the airflow is only partially blocked and air moves through the mouth in a steady stream
Voiced: v, th(that), z, 3(vision)
Unvoiced: f, th(thigh), s, sh(ship), h
Affricates
Produced by putting plosives and fricatives together
Voiced: d3(judge)
Unvoiced: ch(church)
Approximants
Similar to vowel sounds
Voiced: w, r, j(yes)
Nasals
By air moving through the nose
Voiced: m, n, nl(ng)
Laterals
By placing the tongue on the ridge of the teeth and then air moving down the side of the mouth
Voiced: l
