语音分析软件Praat在维吾尔语边界后音段延长的声学语音学中的应用

Application of speech analysis software Praat in acoustic phonetics of the extension of post-boundary segment in Uygur language

文章运用声学语音学的方法,利用语音分析软件分析维吾尔语韵律层级对边界后音段延长的影响,以及边界后音段延长的表现形式和变化规律。结果表明:维吾尔语存在边界后音段延长,表现为韵律短语边界后辅音延长,语调短语边界后元音延长。韵律层级对边界后首辅音延长具有显著性影响。这一结论印证了韵律边界后音段延长具有语言普遍性的结论,也为维吾尔语语音合成提供韵律遵循。

In this paper, acoustic phonetics is used to analyze the influence of prosodic level on the extension of post-boundary segments in Uygur language, as well as the forms and changes of the extension of post-boundary segments. The results show that there is a postboundary segment extension in Uygur language, which is represented by the extension of the consonant after the prosodic phrase boundary and the extension of the vowel after the intonation phrase boundary. The prosodic level has a significant effect on the extension of the first consonant after the boundary. This conclusion confirms the conclusion that the extension of post-boundary segment is universal, and it also provides the prosody for Uygur speech synthesis.
