本文是北京话两字组正常重音的初步实验报告。这里所谓两字组限于前后字都不带对比重音,并且后字不是轻声的两字组。本报告运用概率直方图和相对分布图等统计方法,处理正常重音的物理实验数据和听辨试验数据。从结果看,除前字带对比重音或后字是轻声的两字组外,北京话里并不存在一定要读前重的两字组。后字比前字读得重一些,在听感上觉得后字比前字突出清晰一些,这是北京话两字组正常重音的主要现象。这种正常重音的声学特性,主要是有较长的长度和较完整的音高模式,至于音强,一般不起什么作用。
This article is a preliminary test report of the normal stress of the Beijing dialect. The so-called two-word group is limited to the words before and after without comparison stress, and the word after the word is not soft tone. This report uses statistical histograms such as probability histograms and relative distribution maps to process the physical and empirical data of normal stress. Judging from the results, apart from the former words with contrast or accent after the word is softly two words, the Beijing dialect does not exist must be read before the weight of the two words. After the word read a little heavier than the first word, in the sense of hearing after word than the former words to highlight a number of clear, which is the dialect of Beijing dialect normal stress the main phenomenon. The acoustical characteristics of this normal accent are mainly of longer length and more complete pitch pattern. As far as the sound intensity is concerned, it is generally not useful.
