Perception, evaluation and acquisition of dynamic characteristics of voice individuality

本研究的目的是分析说话人个性的动态特征的产生和感知。这些方面包括韵律特征的各个方面，如语速、词的口音、语调和同化，特别是鼻化和去声的元音。在说话人识别实验中，语速、语调、鼻化元音和方言口音模式等特征对说话人的识别率影响很大。在对JFL学习者的模仿任务(重复和/或掩饰)中，语速和语调模式容易发生变化，但重音模式变化不大。

The purpose of the research is to analyze production and perception of so-called dynamic characteristics of speakers' individuality. These include the various aspects of prosodic features such as speech rate, word accent, intonation and assimilation, especially, nasalized and devoiced vowels. In the experiment of speakers' identification, it was showed the characteristics of speech rate, intonation, nasalized vowels and dialectal accent pattern influenced highly on the identification rate of speakers. In the imitation tasks(repeating and/or shadowing) with the JFL learners, the speech rate and intonation pattern were easily changed, but not word accent pattern.
