The major purposes of this study were to provide normative data on articulation rate in preschool children and to examine the influence on articulation rate of age, gender, context, and utterance length. The subjects were twenty 3-year-old children and twenty 5-year-old children, equally balanced for gender. Durational measures of utterances were analyzed in syllables and phones per second in both spontaneous and imitated speech contexts. The articulation rate of the 5-year-old subjects was significantly faster than that of the 3-year-olds. Spontaneous speech was significantly faster and more variable than imitated speech. Some gender differences were found. Measures in syllables per second and phones per second, although not always yielding identical results, were found to be highly correlated.
本研究的主要目的是提供学龄前儿童发音速率的规范数据，并考察年龄、性别、语境和话语长度对发音速率的影响。研究对象为20名3岁儿童和20名5岁儿童，性别均衡。在自发和模仿言语语境中，对话语的时长进行分析，以每秒音节数和音素数为单位。5岁儿童的发音速率显著快于3岁儿童。自发言语比模仿言语显著更快且更具变异性。发现了一些性别差异。每秒音节数和每秒音素数的测量结果虽然并不总是一致，但发现两者高度相关。
