爱荷华州发音规范项目及其在内布拉斯加州的复制项目的目的是提供这两个州语音习得的规范性信息。评估工具，包括照片和检查表的形式，以学校为基础的语音语言病理学家管理的年龄范围为3-9岁的儿童分层样本。所得数据不受人口密度（农村/城市）、社会经济地位（基于父母教育程度）或居住州（爱荷华州/内布拉斯加州）等人口统计学变量的影响;然而，儿童的性别对某些学龄前年龄组产生了显著影响。用于确定产品可接受性的标准似乎会影响某些语音的结果。绘制了单个音素目标或目标组的获取曲线。这些曲线被用来制定建议的年龄收购的测试语音声音，建议一般基于90%的收购水平。需要对音素/ng s z/进行特殊考虑。
The purpose of the Iowa Articulation Norms Project and its Nebraska replication was to provide normative information about speech sound acquisition in these two states. An assessment instrument consisting of photographs and a checklist form for narrow phonetic transcription was administered by school-based speech-language pathologists to stratified samples of children in the age range 3-9 years. The resulting data were not influenced by the demographic variables of population density (rural/urban), SES (based on parental education), or state of residence (Iowa/Nebraska); however, sex of the child exerted a significant influence in some of the preschool age groups. The criteria used to determine acceptability of a production appeared to influence outcomes for some speech sounds. Acquisition curves were plotted for individual phoneme targets or groups of targets. These curves were used to develop recommended ages of acquisition for the tested speech sounds, with recommendations based generally on a 90% level of acquisition. Special considerations were required for the phonemes /ng s z/.
