对维吾尔语的韵律结构进行了全面的研究,从维吾尔语语音合成(TTS)语音库中提取了音节的时长、能量、基频均值、最大值、最小值和基频范围等韵律特征参数,分析了其在音节处于不同韵律层次时的变化规律。提取了语音数据中韵律边界前后的音节延长量、音高重置和无声段等声学特征参数,并对它们的分布规律进行了统计分析。实验结果表明:不同韵律层级之间时长延长量和音高差值随着边界层级的提高而增加;韵律词边界之间没有显著地停顿,韵律短语和语调短语层级边界之间的平均停顿时长分别是154.2和212.8ms。
The prosodic structure of Uyghur language is comprehensively studied. The prosodic feature parameters such as duration, energy, fundamental frequency mean, maximum value, minimum value and fundamental frequency range of syllables are extracted from Uyghur speech synthesis (TTS) The variation of syllables at different rhythm levels. The acoustic parameters such as syllables extension, pitch reset and silent segments were extracted before and after the prosodic boundary in speech data, and their distribution rules were statistically analyzed. The experimental results show that the duration and pitch differences between different prosodic levels increase with the increase of the boundary level. There is no significant pause between the prosodic word boundaries, and the average pause duration between the prosodic phrases and the intonational level boundaries is 154.2 and 212.8ms.
