摘要
在声调语言环境下成长的婴儿的前语言阶段的音高发展呈现什么样的规律,为儿童语言习得领域中一重要研究课题,但迄今相关研究甚少。基频负载着声调的主要区别特征。实现基频的直接物质是声门。而此阶段的婴儿声门处于不稳定的状态。本文指出婴儿前语言阶段音高的发展规律的研究应该采用对数 z-score(LZ)的方法,与此相应的频域定义取平均值和标准偏差,对婴儿的前语言阶段(八个月到一岁三个月或更早)的音高进行归一化。并采用软件 Praat 进行语音分析。指出了婴儿前语言阶段的音高规律研究的意义和研究方法。
What are the characteristics of the pitch development at the babbling stage with a tone language background? F0 mainly determines the tone. And the vocal cord is the physical material making the F0.The kid’s vocal cord still develops. This paper aims to point out the necessity of making the pitch normalization of a kid at the prelinguistic stage with the Lz-score method and relevant mean value and standard deviation and doing the data analysis with the software Praat. And it states the significance and scientific method about the study on characteristics of pitch at the prelinguistic stage.
