摘要
该文根据语音合成和语音识别的实际需求出发,从实验语音学的角度从《维吾尔语语音参数库中》选择了带元音/u/的330个音节词,分别对非清化状态和清化状态下进行语音学研究。在非清化状态下,对其元音的共振峰值进行了统计分析,归纳了共振峰分布特点来考察元音/u/的基本声学特征,结合实验结果对该元音的语音特点做进一步讨论分析。再对其元音发生清化和保持原来浊特性时的时长,音高和音强进行了统计分析,归纳了其发生清化时的时长,音强,共振峰的分布模式,探讨了元音/u/的清化特性,并验证了语音学者凭听力和生理而总结出来的结论和声学上的结论的一致性。其目的是为了提高语音合成的自然度,即更好地为自然语言处理服务。
In this paper according to the actual requirements of speech synthesis and speech recognition, chosen from 330 syllable words with vowel/u/in Uyghur Language Acoustical database. First of all, the investigation is concentrated on an statistical analysis of the Formant, and generalize the Formant distribution to examine the vowel/u/basic acoustic features when they keep their original voiced features, and summarizes some important rules and conclusions. Then the investigation is concentrated on an acoustical analysis of the duration, pitch and intensity features of the vowels/u/in Uyghur when they become voiceless as well as when they keep their original voiced features. With the purpose of improve the naturalness of speech synthesis that is better for natural language processing services.
