中文摘要：

该文从提高语音合成自然度的实际需求出发,首次从实验语音学的角度从《维吾尔语语音声学参数库》中统计出了333个三音节词,其中再筛选了93个全和谐词和半和谐词,并对其元音的宽带共振峰模式、共振峰值、音高、时长和音强等韵律参数进行了统计分析,归纳了其共振峰、音高、时长和音强分布特点来考察元音和谐的基本声学特征,总结出了一些重要的规则和结论,为参数式或波形拼接式语音合成系统中调整合成前的元音和谐问题提供了重要的参考依据。

英文摘要：

A statistical analysis is carried on 93 complete/incomplete vowel harmonious words chosen from 333 tri- syllabic words in Uyghur I.anguage Acoustical Database. It is focused on the basic acoustic features of tri-syllabic complete/incomplete harmonious words including the broadband resonance peak mode, resonance peak value, vowel duration, vowel pitch and the sound intensity. The rules and findings are of great importance for adjusting vowel harmony in synthesis sub-procedure of parametric or waveform concatenation based speech synthesis system.
