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.
婴儿早期的咿呀学语使他们能够在清晰表达、有意义的词汇成为其产出词汇的一部分之前，与照顾者进行初步的对话。此外，咿呀学语中经过精心练习的声音起到了感知“过滤器”的作用，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。本研究使用 44 名 10-11 个月大婴儿的自然家庭录音（这个年龄段在早期言语声音产生方面具有高度变异性），测试婴儿早期的辅音产生是否与他们环境中的单词和物体相匹配。我们发现，婴儿的咿呀学语与照顾者言语中的辅音相匹配。具有成熟辅音音系的婴儿也将他们的咿呀学语与环境中的物体相匹配。我们的研究结果表明，婴儿的早期辅音产生受到其输入的影响：到 10 个月大时，咿呀学语的声音与婴儿所见所闻相匹配。
