这里的实验是建立在广泛报道的发现，儿童是最准确的时候生产高环境语言频率的语音序列。仍然存在争议的是对儿童必须跟踪这种效应产生的输入的描述。我们提出了一系列的实验，比较两个环境语言的属性，令牌和类型的频率，因为它们有助于语音定位学习。标记频率是孩子接触特定模式的原始数量;类型频率是指抽象实体的数量，例如独特的单词。我们的研究结果表明，儿童的生产准确性是最敏感的类型和令牌频率的组合：儿童能够概括一个目标phonotactic序列时，熟悉多个字类型的令牌从多个谈话者一个新的单词，但不是当呈现的单词类型没有谈话者的变化或多个谈话者令牌的一个单词。
The experiments here build on the widely reported finding that children are most accurate when producing phonotactic sequences with high ambient-language frequency. What remains controversial is a description of the input that children must be tracking for this effect to arise. We present a series of experiments that compare two ambient-language properties, token and type frequency, as they contribute to phonotactic learning. Token frequency is the raw number of exposures children have to a particular pattern; type frequency refers to a count of abstract entities, such as unique words. Our results suggest that children’s production accuracy is most sensitive to a combination of type and token frequency: Children were able to generalize a target phonotactic sequence to a new word when familiarized with multiple word-types across tokens from multiple talkers, but not when presented with either word-types with no talker variability or multiple talker-tokens of a single word.
