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。
Starting from the actual demand of improving the naturalness of speech synthesis, the article first counted 333 three-syllable words from “Uyghur Speech Acoustics Parameter Library” from the perspective of experimental phonetics, and then screened 93 complete harmony words and half Harmony, and its prosodic parameters such as the wideband formant pattern, the resonance peak, the pitch, the duration and the sound intensity of its vowel were analyzed statistically, and its resonance peak, pitch, duration and distribution of sound intensity were summarized to investigate the vowel harmony And summarizes some important rules and conclusions. It provides an important reference for adjusting the vowel harmony before synthesis in parametric or waveform mosaic speech synthesis system.
