Infants' early babbling allows them to engage in proto-conversations with caretakers, well before clearly articulated, meaningful words are part of their productive lexicon. Moreover, the well-rehearsed sounds from babble serve as a perceptual 'filter', drawing infants' attention towards words that match the sounds they can reliably produce. Using naturalistic home recordings of 44 10-11-month-olds (an age with high variability in early speech sound production), this study tests whether infants' early consonant productions match words and objects in their environment. We find that infants' babble matches the consonants produced in their caregivers' speech. Infants with a well-established consonant repertoire also match their babble to objects in their environment. Our findings show that infants' early consonant productions are shaped by their input: by 10 months, the sounds of babble match what infants see and hear.

从牙牙学语到单词:婴儿的早期作品与环境中的单词和物体相匹配



婴儿早期的牙牙学语使他们能够与看护者进行原始对话,而早在清晰表达、有意义的单词成为他们富有成效的词汇的一部分之前。此外,经过精心排练的牙牙学语声音可以充当感知“过滤器”,将婴儿的注意力吸引到与他们能够可靠发出的声音相匹配的单词上。这项研究使用 44 名 10 至 11 个月大的婴儿(早期言语声音产生高度可变的年龄)的自然家庭录音,测试婴儿的早期辅音发音是否与其环境中的单词和物体相匹配。我们发现婴儿的牙牙学语与照顾者说话时发出的辅音相匹配。拥有完善辅音功能的婴儿也会将他们的牙牙学语与环境中的物体相匹配。我们的研究结果表明,婴儿早期辅音的发音是由他们的输入决定的:到 10 个月时,牙牙学语的声音与婴儿看到和听到的声音相匹配。
