爱荷华-内布拉斯加州发音规范项目（Smit、Hand、Freilinger、Bernthal 和 Bird，1990）中儿童所犯的辅音单音错误按年龄范围和频率制成表格。突出的错误类型通常可以被描述为语音过程，但也存在其他常见错误，尤其是液体和摩擦音的扭曲。此外，一些相关的语音过程似乎受到它们所应用的辅音或词位范围的限制。提出了一种基于使用频率的度量来确定错误类型是否非典型。检查不同年龄范围内错误类型频率的变化，以确定某些非典型错误类型是否可能是发育性的，即随着孩子的成熟可能会自我纠正。最后，探讨了这些数据在评估和干预方面的临床应用。
The errors on consonant singletons made by children in the Iowa-Nebraska Articulation Norms Project (Smit, Hand, Freilinger, Bernthal, & Bird, 1990) were tabulated by age range and frequency. The prominent error types can usually be described as phonological processes, but there are other common errors as well, especially distortions of liquids and fricatives. Moreover, some of the relevant phonological processes appear to be restricted in the range of consonants or word-positions to which they apply. A metric based on frequency of use is proposed for determining that an error type is or is not atypical. Changes in frequency of error types over the age range are examined to determine if certain atypical error types are likely to be developmental, that is, likely to self-correct as the child matures. Finally, the clinical applications of these data for evaluation and intervention are explored.
