The impact of input frequency (IF) and functional load (FL) of segments in the ambient language on the acquisition order of word-initial consonants is investigated. Several definitions of IF/FL are compared and implemented. The impact of IF/FL and their components are computed using a longitudinal corpus of interactions between thirty Dutch-speaking children (age range: 0 ; 6-2 ; 0) and their primary caretaker(s). The corpus study reveals significant correlations between IF/FL and acquisition order. The highest predictive values are found for the token frequency of segments, and for FL computed on minimally different word types in child-directed speech. Although IF and FL significantly correlate, they do have a different impact on the order of acquisition of word-initial consonants. When the impact of IF is partialed out, FL still has a significant correlation with acquisition order. The reverse is not true, suggesting that the acquisition of word-initial consonants is mainly influenced by their discriminating function.
本文研究了环境语中语段的输入频率（IF）和功能负荷（FL）对词首辅音习得顺序的影响。比较并实现了几种 IF/FL 的定义。使用三十名荷兰语儿童（年龄范围：0 ； 6-2 ； 0 岁）与其主要照顾者之间互动的纵向语料库，计算了 IF/FL 及其组成部分的影响。语料库研究揭示了 IF/FL 与习得顺序之间存在显著相关性。在词段的标记频率和儿童导向言语中最小不同词类上计算的 FL 中，发现了最高的预测值。尽管 IF 和 FL 显著相关，但它们对词首辅音习得顺序的影响不同。当 IF 的影响被部分消除时，FL 与习得顺序仍然存在显著相关性。反之则不然，这表明词首辅音的习得主要受其区分功能的影响。
