【摘要】：言语中的停延时长分配不当,影响听众对语句语法结构层次、感情色彩等语义信息的获取,也会降低说话者的言语可懂度。临床中我们发现,痉挛型脑瘫儿童的口语中存在停延时长过长而导致的语音断续度大和音节黏连层次不清的现象,这降低了他们的言语清晰度。然而,对痉挛型脑瘫儿童停延的关注仅停留在经验层面,实证研究匮乏。与普通儿童相比,痉挛型脑瘫儿童的在各韵律层级下的停延有何特征,这是本研究拟解决的首要研究问题;两类儿童在各韵律层级下的停延时长与言语清晰度(声韵母的字清晰度与句清晰度)间的相关性如何,这是本研究拟解决的第二个问题;声韵母类型是否影响异常停延的发生率,这是本研究拟解决的第三个问题。为了解决这些问题,本研究将比较两类儿童在跟读语言任务下的停延时长,分析痉挛型脑瘫儿童在各韵律层级下的停延时长特征;将两类儿童各韵律层级下的停延时长分别与其言语清晰度做相关,探讨其停延时长与言语清晰度之间的关系;总结两类儿童不同类型声韵母异常停延发生率状况。本研究主要研究内容及结果如下:1.痉挛型脑瘫儿童在各韵律层级下的停延特征在儿童类型上,痉挛型脑瘫儿童的停延时长显著高于普通儿童,且降低了其言语流利性;韵律层级上,随着韵律层级的上升,停延时长也增加。2.两类儿童在各韵律层级下的停延时长与其言语清晰度的相关性普通儿童:普通儿童在各韵律层级下的停顿时长与声母的字清晰度、句清晰度呈中、强度负相关;在各韵律层级下的音节拖延时长与韵母的字清晰度、句清晰度呈中度负相关。脑瘫儿童:痉挛型脑瘫儿童在各韵律层级下的停顿时长、音节时长与声韵母的字清晰度、句清晰度均存在中、强度负相关。3.两类儿童不同类型声韵母异常停延的发生率声韵母类型会影响儿童异常停延的产生,随着声韵母构音难度的增加异常停延的发生率也随之上升。
[Abstract]:The improper allocation of pause delay in speech affects the audience's acquisition of semantic information such as grammatical structure and emotional color. It also reduces the speech intelligibility of the speaker. In clinic we found that the speech of children with spastic cerebral palsy has the phenomenon of too long stop delay which leads to a large degree of discontinuity and unclear syllable levels which reduces their speech articulation. However, the focus on children with spastic cerebral palsy is limited to empirical level, and empirical research is scarce. Compared with the common children, the characteristics of children with spastic cerebral palsy in the different prosodic levels are the most important research issues to be solved in this study. The second problem to be solved in this study is the correlation between the length of stop delay and the articulation of speech (word clarity and sentence clarity) between the two types of children at different prosodic levels. Whether the mother type of rhyme affects the incidence of abnormal delay is the third problem to be solved in this study. In order to solve these problems, this study will compare the length of stop delay of two kinds of children under the task of following reading language, and analyze the characteristics of stop delay of children with spastic cerebral palsy at different prosodic levels. In order to explore the relationship between stop delay and speech intelligibility, the two kinds of children's stopping delay length under each prosodic level is related to their speech articulation, and the occurrence rate of abnormal stop and delay of two kinds of children's different types of rhyme and initial rhyme are summarized. The main contents and results of this study are as follows: 1. The stopping delay of children with spastic cerebral palsy was significantly longer than that of the normal children, and decreased the fluency of speech in the children with spastic cerebral palsy at different prosodic levels, and at the prosodic level, with the increase of the prosodic level, the delay time of the children with spastic cerebral palsy was significantly longer than that of the normal children. Stop delay also increased. 2. The correlation between stop delay length and speech intelligibility of two kinds of children at each prosodic level: the pause duration of ordinary children at each prosodic level is negatively correlated with the word clarity of the consonant and the intensity of sentence clarity; The duration of syllable procrastination at each prosodic level is negatively correlated with the articulation of the vowel and the articulation of the sentence. Children with cerebral palsy: the duration of pauses, syllable duration and initial word clarity, sentence clarity of spastic cerebral palsy children at different prosodic levels were negatively correlated with the intensity. 3. The incidence of abnormal stop of two types of children will affect the occurrence of abnormal stop, and the incidence of abnormal stop will increase with the increase of the difficulty of consonant conformation.
