婴儿早期的牙牙学语使他们能够与看护人进行原型对话,早在清晰表达之前,有意义的词语就成为他们富有成效的词汇的一部分。此外,婴儿牙牙学语中排练好的声音可以作为感知的“过滤器”,将婴儿的注意力吸引到与他们能够可靠地发出的声音相匹配的单词上。使用自然主义的家庭录音44个10-11个月大的婴儿(一个年龄与早期语音产生的高度可变性),这项研究测试婴儿的早期辅音生产是否匹配的话和物体在他们的环境。我们发现婴儿的牙牙学语与他们的照顾者说话时产生的辅音相匹配。具有良好辅音库的婴儿也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,婴儿早期的辅音产生是由他们的输入形成的:到10个月时,婴儿的牙牙学语的声音与婴儿看到和听到的声音相匹配。
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.
