Perceptual normalization of inter- and intra-talker variations in tone categorization: 声调感知中话者间及话者内差异的归一化.
人类如何在颜色、视觉对象和听觉对象存在很大差异的情况下实现感知恒定,这是认知神经科学的一个根本问题。大脑处理差异的一个重要办法是依靠背景环境,为感知颜色、视觉对象和听觉对象提供参照。在语音感知中,在言语信号中存在话者间以及话者内差异的情况下实现语音恒定也是很关键的。根据语境归一化机制,听者可以通过语境(即目标语音周围的其他语音)适应话者的语音空间。在本论文中,我以声调为例考察了语音恒定的问题。 === 第一,在一个跨语言研究中,我发现不同语音系统的结构会影响听者听辨多个话者所发的声调。普通话听者可以不靠语境准确地听辨多个话者所发的声调,而广东话听者则被多个话者间的音高差异误导。这一不同可以归根...
