语音学视角下语义第二焦点的声学研究

摘要

The semantic second focus refers to the repeated early focus items,commonly modified by one of the focus-sensitive operators.The semantic second focus,called as"the invisible focus in phonology",it commonly does not embody the same a-coustical features as the first focus does.Its acoustical characters mainly are lack of pitch movement,but are marked by longer duration and greater energy.These characters can be explained from the perspectives of post-nuclear de-accenting and the phrasal stress.%语义上的第二焦点是指的在上文提到过的、往往有焦点敏感算子限定修饰的句子成份.语义上的第二焦点被称为"音系学中看不到的焦点",通常不具备第一焦点所具有的有着明显的音高突现,和较长的音长、较强的音强等语音学上的声学特征.其声学特征具体表现为:缺少音高重音,没有音高移动;有明显的较长音长、较强的音强和能量.这种声学特征可从调核后失重读和短语重读角度给予解释.
