Features associated with the production of linguistic prosody were investigated in seven speech-disordered children and seven children with age-appropriate speech abilities. All subjects were required to imitate 40 stimuli containing either a rising or falling terminal contour. Half of the stimuli were meaningful sentences whereas the other half were nonmeaningful repetitions of a single syllable. Both types of stimuli were produced with the same suprasegmental features. Acoustic analyses were used to measure a variety of prosodic features associated with the intonation (Fo) and timing characteristics of the imitated stimuli. The primary differences between the two groups of children focused on timing characteristics of the imitated responses. Differences in Fo characteristics also were identified, but in some instances interacted with timing deviations. Results are discussed in reference to potential physiologic and/or linguistic processes that might contribute to dysprosody in speech-disordered children.
研究人员对七名言语障碍儿童和七名言语能力与年龄相符的儿童进行了与语言韵律产生相关特征的调查。所有受试者都被要求模仿40个刺激，这些刺激包含上升或下降的结尾语调轮廓。其中一半的刺激是有意义的句子，而另一半是单个音节的无意义重复。两种类型的刺激都具有相同的超音段特征。声学分析被用于测量与模仿刺激的语调（基频）和时间特征相关的各种韵律特征。两组儿童之间的主要差异集中在模仿反应的时间特征上。也确定了基频特征的差异，但在某些情况下，这些差异与时间偏差相互作用。研究结果将结合可能导致言语障碍儿童韵律障碍的潜在生理和/或语言过程进行讨论。
