The syllable repetitions of 6 child and 6 adult stutterers were investigated to establish whether dysfluent speech had a higher noise-to-signal ratio than fluent speech and whether this differed between children and adults. As predicted, the stuttered speech had a higher noise level for both age groups. During dysfluencies, the level of the noise components in the children's speech was higher than in the adults.
对6名儿童和6名成年口吃者的音节重复进行了研究，以确定不流畅言语的噪声与信号之比是否高于流畅言语，以及儿童和成人之间是否存在差异。正如所预测的，两个年龄组的口吃言语都有更高的噪声水平。在言语不流畅期间，儿童言语中噪声成分的水平高于成人。
