该文根据语音合成与识别等语音应用研究的需求,从文本分析模块入手,利用“维吾尔语语音声学参数库”,选择了包含鼻音m、n和的单音节以及多音节词,提取它们的声学参数并进行统计分析,归纳了其共振峰、音强和时长分布模式,研究了鼻音的两个变体,从实验语音学的角度出发进一步探讨了鼻音的声学特性,并总结出了一系列结论。其目的是为了提高语音合成的自然度即更好的为自然语言处理服务。该项研究结果对维吾尔语语言乃至整个阿尔泰语系语言的韵律研究具有较高的参考价值。

To improve the naturalness of speech synthesis system, the paper presents a systematic empirical study on the nasal in Uyghur language as an enrichment of the prosody in Uyghur language. The experimental analysis is carried on an acoustical database with prosodic measurements from the word of containing nasals, recorded by 1 male 1 female speaker. The investigation concentrates on an acoustical analysis of the prosodic features of the nasal in Uyghur language, including formant, length, intensity and duration etc. To our best knowledge, this is the first study in this aspect for Uyghur language, which is enlightening for the study of entire Altay language family as well.
