连续语音下学龄期脑瘫的流利性特征及其与言语可懂度的相关性

Objective To explore the characteristics of speech fluency of school-age children with cerebral palsy in connected speech and its correlation with speech intelligibility, in order to provide theoretical basis for assessment and rehabilitation of speech fluency in children with cerebral palsy. Methods Totally 15 children with spastic cerebral palsy and 15 normal children with the same age were enrolled in this study from January to February 2021. The acoustic parameters related to speech fluency were analyzed by reading the speech-balanced reading materials, including speech rate, articulation rate, average pause duration, number of abnormal pauses, and number of repetitions. Speech intelligibility were judged by transcription. Spearman correlation analysis was carried out to analyze the correlation between the acoustic parameters related to speech fluency of children with cerebral palsy and their speech intelligibility. Results The speech rate, articulation rate, and speech intelligibility of children with cerebral palsy were significantly lower than those of the control groupO: — 21.650, — 15.440, —4.447, P<0.05), while the average pause duration, the number of abnormal pause and the number of repetitions were significantly greater than those of the control groupG:19. 639, 20. 347, 3. 767, P<0. 05). The speech rate (r: 0.831), articulation rate (r: 0.827), average duration of pauses (r:—0.849) were positively correlated with speech intelligibility, while the number of abnormal pauses (r: —0. 783) and the number of repetitions (r:—0. 672) of children with spastic cerebral palsy were negatively related to speech intelligibility (P<0. 01). Conclusion Children with spastic cerebral palsy have lower speech intelligibility and abnormal speech fluency, which was reflected in the slower speech rate, the increasing number of abnormal pauses, average pause duration and the number of repetitions. Speech fluency in children with cerebral palsy is positively correlated with speech intelligibility, and the training of speech fluency should be reasonably added to the speech treatment of cerebral palsy.
