对儿童发展的自然纵向记录有望揭示关于语言习得基本问题的新观点。在试点工作中，我们录制了 230,000 小时的音频视频记录，涵盖一个孩子在家生活的前三年。要研究如此规模和丰富的语料库，当前的发展认知科学方法还不够。我们正在开发新的数据分析和解释方法，将模式识别算法与交互式用户界面和数据可视化相结合。初步的言语分析揭示了护理人员令人惊讶的语言微调水平，这可能为单词学习提供重要支持。对语料库的持续分析旨在将儿童语言发展的详细方面建模为学习机制与一生经验相结合的函数。基于可移动记录系统从更多儿童收集类似语料库的计划正在进行中。
Naturalistic longitudinal recordings of child development promise to reveal fresh perspectives on fundamental questions of language acquisition. In a pilot effort, we have recorded 230,000 hours of audio-video recordings spanning the first three years of one child’s life at home. To study a corpus of this scale and richness, current methods of developmental cognitive science are inadequate. We are developing new methods for data analysis and interpretation that combine pattern recognition algorithms with interactive user interfaces and data visualization. Preliminary speech analysis reveals surprising levels of linguistic fine-tuning by caregivers that may provide crucial support for word learning. Ongoing analyses of the corpus aim to model detailed aspects of the child’s language development as a function of learning mechanisms combined with lifetime experience. Plans to collect similar corpora from more children based on a transportable recording system are underway.
