汉维右脑损伤患者语言韵律特征对比研究

A Comparative Study of Language Rhythm Characteristics of Chinese and Uyghur Patients of Right-brain Damage

对汉族和维吾尔族右脑损伤患者产出的陈述和疑问语调、声调和重音进行声学分析,结果表明:患者语调调域变窄,句末音高为降调,陈述语调的呼吸群特征相对保留;语速缓慢,音节和句子时长均受到损伤;汉族患者的声调特征也受到损伤,而维吾尔族患者的重音特征相对保留。受声调和非声调语言经验的影响,汉族和维吾尔族患者处理语言韵律的神经机制存在差异。

An acoustic analysis has been made of the intonation, tones and stress of declarative and interrogative sentences by Chinese and Uyghur patients suffering from right-brain damage. The findings show that their tone-range becomes narrower, their pitch descends at the end of the sentences, and they still maintain breath group characteristics in their declarative tone. Their speaking speed is slow with some damage in syllables and sentence length. The Chinese patients＇ tone characteristics are also damaged, while the Uyghur ones still keep their stress characteristics. Under the influence of tone and non-tone languages, Chinese and Uyghur patients use different neutral mechanisms to deal with language rhythm.
