Abstract

This article evaluates the ''Frames, then Content'' hypothesis for speech acquisition, which states that much of the patterning of babblingis a direct result of production of syllabic ''Frames'' by means of rhythmic mandibular oscillation, with relatively little of the intrasyllabic and intersyllabic ''Content'' of the syllable-like cycles under mandible-independent control. Analysis was based on a phonetically transcribed corpus of 6,659 utterances of 6 normally developing infants obtained from one-hour weekly audio-recordings over a 4-6 month period. Intrasyllabic predictions were that front vowels would preferentiallyco-occur with front (alveolar) consonants, back vowels with back (velar) consonants, and central vowels with labial consonants, with the latter effect presumably resulting from mandibular oscillation alone. Intersyllabic predictions were for more variegation in tongue height forvowels than in front-back tongue movement, and for consonant manner changes to predominate over place changes (related primarily to mandibular oscillation). All 30 individual predictions from both hypotheses were confirmed, leading to a conception of the articulatory basis of babbling as ''Frame Dominance.''
