本文评估了语音习得的“框架，然后内容”假设，该假设指出，牙牙学语的大部分模式是通过有节奏的下颌振动产生音节“框架”的直接结果，在下颌独立控制下，音节状循环的音节内和音节间“内容”相对较少。分析基于 6 名正常发育婴儿的 6,659 条语音转录语料库，该语料库是从 4-6 个月内每周一小时的录音中获得的。音节内的预测是，前元音将优先与前（牙槽）辅音同时出现，后元音将优先与后（软腭）辅音同时出现，而中央元音将优先与唇辅音同时出现，而后一种效果可能是仅由下颌振动引起的。音节间预测是元音的舌头高度比前后舌头运动有更多的变化，并且辅音方式的变化比位置变化占主导地位（主要与下颌摆动有关）。这两个假设的所有 30 个单独预测都得到了证实，从而得出了将牙牙学语的发音基础称为“框架优势”的概念。
This article evaluates the ''Frames, then Content'' hypothesis for speech acquisition, which states that much of the patterning of babbling is 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 preferentially co-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 for vowels 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.''
