Document Summary
Cry, fuss, whine, squeal, chuckle, laugh, sucking, smacking, burping, grunting sounds, raspberries: many early sounds are: Emotion-based (cry, squeal, laugh) and linked with movement/arousal. Infants also make some vegetative sounds (suck, burp, lip smack) Speech acquisition: the speech acquisition process begins in infancy. Consonant-like sounds: 4 characteristics of speech-like vocalizations: (adults) Precursor to syllables coordination of respiration and laryngeal closure. Supra-glottal movements coordination with respiration and laryngeal control. Speech acquisition in infancy: speech-like vowels and cv syllables: Differ from later vowels and syllables in quality and timing: speech-like vowels: Differ from later vowels in quality (e. g. resonance: speech-like syllables: Lots of other sounds as well (raspberries, squeals, shrieks, grunts, growls: early words: May resemble the target word sounds and syllable structure. Variable productions- word attempt may vary from time to time: early sounds: Rare sounds: /r/, /z/, ch : possible early concerns. Unusual patterns: your knowledge of sounds acquisition contributes to:
