汉语普通话“是”字焦点句的韵律表现

The Prosodic Features of Focus Sentences with “Shi” in Putonghua

本文从广义的语调出发,选取5位北京发音人的语料对汉语普通话"是"字焦点句进行了系统的实验分析,得到了"是"字句的音高、音长和音强的韵律表现。结果表明:"是"字句的焦点重音主要是由焦点词和焦点之后的相邻词协同作用,焦点前的词作用较小。另外,标记词"是"字的语音弱化现象比较明显。通过和同型强调焦点句的音高、时长进行对比,我们发现:标记词"是"对于其后的焦点重音具有显著的强化作用,进而使其位于更高的重音等级。

Based on the broad sense of intonation,we made a systematic experimental analysis on the focus sentences with "shi"in Putonghua spoken by 5 native Beijing speakers,and obtained the prosodic features of the pitch,duration and intensity.The result suggested that the stress of focus sentences with "shi"mainly depended on the co-effort of focus word and post-focus word.The role of pre-focus word was relatively small.In addition,the phonetic weakening of the marker "shi " was obvious.By comparing the pitch and duration between focus sentences with"shi"and the same type of sentences without"shi",we found that marker"shi"had a significant strengthening effect on the subsequent focus stresses,and then made them in a higher stress level.
