传统的基频和时长等声学参数凸显阳平音节的重音的作用有限,因此该文具体考察了双音节阳平词的词重音的声学关联物。通过对6 000句语料中的1 282个双音节阳平词进行重音标注和声学分析,发现双音节阳平词的词重音表现出特殊的声学关联物:两音节的音高升幅差、音高上升部分时长差和斜率差这3个斜率相关参数。主要体现在:3个斜率相关参数与双音节阳平词的重音类别有较高的相关性,它们均能够为区分前重词和后重词提供线索;在不同的韵律边界下,斜率相关参数对词重音的影响不同;3个参数与重音类别存在一定的对应关系。
Traditional acoustical parameters such as fundamental frequency and duration emphasize the accent of yang-ping syllable. Therefore, this paper examines the acoustical correlations of word-accent of yang-ping syllable. Through the accented annotation and acoustic analysis of 1,282 disyllabic words in 6 000 corpora, it was found that the word accent of disyllabic Yang Ping Ci showed special acoustic correlations: the pitch of the two syllables increased poorly and the pitch increased Time difference and slope difference between the three slope-related parameters. Mainly reflected in: the three slope-related parameters and the two-syllable yangping accent category has a high correlation, they can distinguish between the former heavy words and after heavy words provide clues; in different prosodic boundaries, the slope-related parameters The impact of word stress is different; there is a certain correspondence between the three parameters and stress categories.
