Bye-Bye Bunny: Place and Manner Sequences in Children's C₁VC₂V-Shaped Words

Area of Science:

• Developmental Linguistics
• Speech Acquisition
• Phonological Development

Background:

• Children learning to speak often simplify complex sound patterns in words.
• The transition from babbling to meaningful speech involves mastering word production.
• Understanding how children produce early words informs theories of language acquisition.

Purpose of the Study:

• To investigate the relationship between consonant sequence patterns (place and manner of articulation) in target words and children's actual productions.
• To test the hypothesis that repeated consonant sequences in words are produced more accurately by children.
• To explore the role of consonant onsets in early word matching accuracy.

Main Methods:

• Analysis of 2,092 consonant-vowel-consonant-vowel (C1VC2V) word tokens from 18 typically developing children in the single-word stage.
• Comparison of target word articulation patterns (place and manner) with children's spontaneous speech productions.
• Categorization of consonant sequences as repeated or variegated based on place and manner features.

Main Results:

• Target C1VC2V words predominantly featured repeated place and manner sequences (e.g., labial-labial, stop-stop).
• Children's productions more frequently matched target words with repeated consonant sequences compared to variegated ones.
• Words starting with labial consonants were produced more accurately than those with coronal or dorsal onsets.

Conclusions:

• Children's early word productions align with target words featuring repeated place and manner sequences in C1VC2V forms.
• The findings suggest that repeated sound patterns in salient target words facilitate early vocalizations.
• This supports the idea that phonological simplicity aids children during the transition from babbling to speech.
