在学习感知和产生语音的过程中，儿童掌握了复杂的语言特定模式。令人生畏的语言特有的变化被发现在节段域和韵律和语调域。本文综述了语音类型学和社会语言学的研究成果对语言习得理论提出的挑战。它认为，类别发起自下而上的统计模式，在语音空间的使用，并勾勒出如何范例理论可以用来模拟更新的类别，一旦他们被启动。它还认为，自下而上的启动类别是成功的，这要归功于感知生产循环在言语社区。这种循环的行为意味着婴儿所能获得的言语的表面统计特性间接地反映了成人语法中范畴的对比性和区分性。文章还认为，开发系统是完善使用内部反馈类型统计的词汇，一旦词汇是发达国家。将类型统计应用于由表面统计启动的系统不会导致系统的根本重组。相反，它利用了表征人类语言并使自举成为可能的各个层次的汇合。
In learning to perceive and produce speech, children master complex language-specific patterns. Daunting language-specific variation is found both in the segmental domain and in the domain of prosody and intonation. This article reviews the challenges posed by results in phonetic typology and sociolinguistics for the theory of language acquisition. It argues that categories are initiated bottom-up from statistical modes in use of the phonetic space, and sketches how exemplar theory can be used to model the updating of categories once they are initiated. It also argues that bottom-up initiation of categories is successful thanks to the perception-production loop operating in the speech community. The behavior of this loop means that the superficial statistical properties of speech available to the infant indirectly reflect the contrastiveness and discriminability of categories in the adult grammar. The article also argues that the developing system is refined using internal feedback from type statistics over the lexicon, once the lexicon is well-developed. The application of type statistics to a system initiated with surface statistics does not cause a fundamental reorganization of the system. Instead, it exploits confluences across levels of representation which characterize human language and make bootstrapping possible.
