文章通过语音实验与分析 ,考察了新闻广播语流中字音时长延长的分布情况 ,考察了字音时长的延长与该字音音节的音强、音高上限的相关程度。考察得出了新闻广播语流中字音时长延长的两种类型 :第一种类型是一个语言片段中所有字音的时长都延长 ;第二种类型是整个两字组或三字组中只有一个字音延长。根据这两种类型在语流中的分布特征 ,分析了新闻广播语体中字音时长延长与汉语信息传递之间的关系 ,得出了如下的结论 :一是新信息有主要信息、次要信息之分 ,这些信息单位各有其音系层上的标志 ;二是音节的延长使新信息凸显出来。
Through the experiment and analysis of the speech, this paper examines the distribution of the extended pronunciation of news in broadcast news stream and investigates the correlation between the extension of pronunciation duration and the upper limit of the sound intensity and the pitch of the syllable. Two types of lengthening of phonetic pronunciation in news broadcast stream were investigated: the first type is that all the phonetic sounds in a linguistic fragment are prolonged; the second type is only one phonetic in the whole two-gram or three-grammes extend. According to the distribution characteristics of these two types in the language stream, this paper analyzes the relationship between the extension of phonetic time length and the transmission of Chinese information in the news broadcasting body, and draws the following conclusions: First, the new information has the main information and the secondary information The units of information each have their phonetic level sign; the second is the extension of syllables to highlight the new information.
