本研究的目标是建立一个参考数据库，以便与/S/的发音错误进行比较。对26名9-15岁儿童的声学数据进行了分析，以解决声学分析中的测量问题，包括/S/摩擦中的其他采样点；/S/的4个谱矩中每一个的线性变换和巴克变换的信息量(Forrest，Weismer，Milenkovic，&Dougall，1988)；以及与语言环境、年龄和性别相关的测量效果。对参考数据集的分析表明，(A)从/S/的中点获得/S/的声学特征，(B)以线性标度表示，(C)反映在第一和第三谱矩的汇总统计中，(D)参考单个语言-语音上下文，(E)在所研究的年龄范围内崩溃，以及(F)按性别单独描述。
The goal of the current study was to construct a reference database against which misarticulations of /s/ can be compared. Acoustic data for 26 typically speaking 9- to 15-year-olds were examined to resolve measurement issues in acoustic analyses, including alternative sampling points within the /s/ frication; the informativeness of linear versus Bark transformations of each of the 4 spectral moments of /s/ (Forrest, Weismer, Milenkovic, & Dougall, 1988); and measurement effects associated with linguistic context, age, and sex. Analysis of the reference data set indicates that acoustic characterization of /s/ is appropriately and optimally (a) obtained from the midpoint of /s/, (b) represented in linear scale, (c) reflected in summary statistics for the 1st and 3rd spectral moments, (d) referenced to individual linguistic-phonetic contexts, (e) collapsed across the age range studied, and (f) described individually by sex.
