There are numerous models of how speech segmentation may proceed in infants acquiring their first language. We present a framework for considering the relative merits and limitations of these various approaches. We then present a model of speech segmentation that aims to reveal important sources of information for speech segmentation, and to capture psycholinguistic constraints on children's language perception. The model constructs a lexicon based on information about utterance boundaries and deduces phonotactic constraints from the discovered lexicon. Compared to other models of speech segmentation, our model performs well in terms of accuracy, computational tractability and the number of components of the model. Finally, our model also reflects the psycholinguistic effects of language learning, in terms of the early advantage for segmentation provided by the child's name, and by revealing the overlap in usefulness of information for segmentation and for grammatical categorization of the language.
在婴儿习得第一语言的过程中，有许多关于言语分割的模型。我们提出了一个框架来考虑这些不同方法的优缺点。然后，我们提出了一个言语分割模型，旨在揭示言语分割的重要信息来源，并捕捉儿童语言感知的心理语言学限制。该模型基于关于话语边界的信息构建词汇，并从发现的词汇中推导出音韵规则限制。与其他言语分割模型相比，我们的模型在准确性、计算可处理性和模型组件数量方面表现出色。最后，我们的模型还反映了语言学习的心理语言学效应，例如儿童名字提供的分割早期优势，以及分割和语言语法分类的信息重叠。
