成人和儿童流形通过合成5 × 5 /Cej/型话语矩阵生成，其中F2和F3频率系统变化。在两种条件下向11名研究生水平的言语语言病理学学生展示了多种刺激：(a)评分条件，其中刺激在good /r/和good /w/之间以4分制进行评分；(b)标记条件，其中刺激被标记为“R”，“W”，“扭曲的R”或“N”（之前的选择都没有）。结果发现：(a)低F2频率和高F3频率刺激的评分为1.0 ~ 1.4；F2频率高、F3频率低评分在3.6 ~ 4.0之间的被标记为“R”；(c)没有一个儿童多元刺激被标记为扭曲的“R”，一个成人多元刺激的识别水平接近“R”和“W”的识别百分比；(d)评分和标记任务的可靠性很高。
Adult and Child manifolds were generated by synthesizing 5 X 5 matrices of /Cej/ type utterances in which F2 and F3 frequencies were systematically varied. Manifold stimuli were presented to 11 graduate-level speech-language pathology students in two conditions: (a) a rating condition in which stimuli were rated on a 4-point scale between good /r/ and good /w/; and (b) a labeling condition in which stimuli were labeled as "R," "W," "distorted R," or "N" (for none of the previous choices). It was found that (a) stimuli with low F2 and high F3 frequencies were rated 1.0-1.4; those with high F2 and low F3 frequencies were rated 3.6-4.0 were labeled as "R"; (c) none of the Child manifold stimuli were labeled as distorted "R" and one of the Adult manifold stimuli approached a level of identification that approached the percentage of identification for "R" and "W"; and (d) rating and labeling tasks were performed with a high degree of reliability.
