Study Notes
Infant Anatomy and Physiology
- Infant lungs are larger relative to their size than adult lungs
- Increased subglottal pressure allows infants to cry more forcefully
- Infant larynx is tucked under the chin, squashed, fatter, and thicker than an adult's
- Infant pharyngeal cavity elongates in the first year
- Infant oral cavity is filled by the tongue, acting as a sucking pad
Perceptual Development
- Categorical perception: Listeners perceive speech sounds according to the phonetic categories of their native language.
- Perceptual constancy: Identify a sound as the same across different speakers, pitches, and environmental conditions.
- Infants can discriminate all sounds of all languages up to 6-8 months.
- Discrimination ability of non-native sounds decreases, but the ability to distinguish native sounds increases.
- Early perceptual abilities are linked to later language development.
- Speech perception at 6 months predicts outcomes at 2 years.
Vocal Development Sequence
- Prelinguistic Stage (Birth–12 Months): Occurs before the first word, incorporating gestures. Word comprehension is evident around 7-9 months. Babbling is systematic and limited to small segments, and is related to later language development.
- Canonical babbling should be evident by 10 months.
- Reflexive/Vegetative: Basic sounds.
- Cooing/Laughter: More complex sounds.
- Vocal Play: Experimentation with sounds.
- Canonical Babbling:
- Reduplicated (e.g., "baba").
- Variegated (e.g., "dadada").
- Jargon: Babbling with intonation patterns resembling adult speech.
Vocoids and Contoids
- Vocoids: Vowel-like sounds in babbling.
- Contoids: Consonant-like sounds in babbling.
- Syllable shapes: Refers to the structures of syllables (e.g., CV, VC, CVC). Most common in later babbling periods.
Prosodic Features
- Prosodic features (stress, intonation, pausing, duration) emerge around 6 months.
- Falling pitch is the most frequent pattern in the first year.
- These features are observed in expressive jargon.
- Transition to first words demonstrates similarities to babbling.
- Monosyllabic words predominantly.
- High percentage of stops, then nasals, and fricatives.
- Predominance of bilabial and apical productions.
- Rare use of clusters.
- Central, mid-front, and low-front vowels are common.
First Words & Proto-Words
- True words: Convey consistent meaning, are recognizably similar to adult-word forms.
- Proto-words (invented words): Convey consistent meaning, but are phonetically consistent forms without similarity to an adult model.
Babbling Characteristics and Relation to First Words
- Longitudinal studies show that greater babbling complexity, contoid diversity, and more contoid babble correlate with greater language growth.
Typical vs. Delayed Phonological Development
-
10-month marker: Vowel errors and limited phonetic inventories.
-
Atypical phonological processes:
- Backing
- Initial consonant deletion
- Glottal replacement
-
Red flags for prolonged delay: Limited syllable shapes, inconsistent errors, vowel errors, persistent initial/final consonant deletion, and frequent glottal sounds.
Preschool Phonological Development
- Significant phonological growth between 18-5 years.
- Large growth in expressive lexicon
- Emergent syntax.
- By 5, children have a mostly complete phonological system.
Preschool Vowel Development
- Most vowels are typically mastered by age 3.
- Non-rhotic vowels mastered by 36 months, rhotic vowels around 48-53 months.
Preschool Consonant Development
- Early consonants are reliably learned (p, b, m, d, n, h, etc).
First 50 Words
- Phonetic variability: unstable pronunciations.
- Syllable structures: CV, VC, and CVC syllables predominate in the first 50 words.
- Frequent consonant sounds: Labials, stops, fricatives (especially /h/).
- Frequent vowel sounds: /a, u, i/
- Larger word-initial inventories with more consonants for older children.
- Younger children tend to have fewer sounds at the ends of words.
- High use of correct consonants with a consistent ordering of initial and final-position sounds.
Prosodic Features in the First 50 Words
- Prosodic variation. Pitch variations signal differences in meaning with falling/rising pitch used for requesting, calling, demanding.
School-Age Development
- Mastery of majority of sounds by age 5.
- Fine-tuning of sound production.
- Further development of sounds (ɹ, ʒ, θ, ð) between 5–7 years.
- Consonant and three-element clusters (skw, spr) may still be problematic until around 9 years.
Phonological Awareness
- Correlation between strong phonological awareness skills and later reading ability.
Speech Sound Disorders- Prevalence, Types, & Risks
- 4-6% of school-age children have a speech sound disorder.
- Articulation disorders do not increase risk of other language/reading difficulties.
- Phonological disorders do increase the risk.
Phonological Processes
- Syllable structure processes: affect syllable structure (e.g., final consonant deletion, reduplication).
- Substitution processes affect production features: (e.g., gliding, fronting, stopping, backing)
- Assimilation processes: one sound adapts to properties of other sounds.
Phonetics: Basic Concepts
- Transcription: documenting real speech events (descriptive, not prescriptive).
- Parameters of consonants/vowels (place, manner, voice), (portion/position of tongue, lip rounding)
- Vowel quadrants: illustrate tongue position.
- Diphthongs (changes in sound quality) / phonemic vs. nonphonemic. (Change meaning in word/does not change meaning)
- Diacritics (additional transcription marks)
Coarticulation and Assimilation
- Coarticulation: consonant positioning of the articulators.
- Assimilation: adaptive vocabulary changes in which one sound becomes similar to a neighboring sound.
Major Speech Sound Theories
- Distinctive features theory: sounds are distinguished by features.
- Generative theory: phonological rules account for sound sequences.
- Natural phonology: innate, universal phonological processes drive development.
Cultural Linguistic Diversity
- Identifying phonological forms of dialects is challenging under age 4 (due to immature motor systems).
- AAE phonology may overlap with or be confused by phonological processes in general.
- Impact on phonological awareness and phoneme-grapheme link.
- Lower reading ability in AAE-speaking children.
Contrast of Disorder vs. Difference
- Contrastive forms: create different meanings (e.g., 3rd person singular, past tense).
- Non-contrastive forms: may be dialect variations/unrelated to language disorders (e.g., articles, demonstratives).
