西北师范大学本科毕业论文兰州方言的声学特征分析 I 兰州方言的声学特征分析摘要首先,本文在分析目前关于方言的研究现状的基础上,发现目前对兰州方言的研究主要是从语言学角度来分析,目前,对兰州方言语言学的研究比较深入, 但是从语音学角度的分析还不是很多,鉴于这些情况,我选择了兰州方言作为研究对象。其次,在查阅资料的基础上,结合兰州方言和普通话之间的声韵调差别,设计了文本语料库,该语料库包含了单字 280 个,双音节字 2000 个,以及句子 30 个,并且对这些文本语料进行了兰州方言和普通话平行的语音语料的录制,对语音语料进行了切分、标注,该语料库可以用于分析、合成。最后,对语音语料进行了详细的分析,分析的内容主要包括对双字组基频值的分析,以及双字组合中发生连续变调的情况。在双字的组合中,有的基频值保持了单字的基频不变,有的则发生变化,产生了新的调型调值,这些将为转换提供依据,为合成打下基础。关键字:兰州方言文本语料语音语料切分标注声学分析西北师范大学本科毕业论文兰州方言的声学特征分析 II Abstract First of all, Based on the analysis of the current research on the dialects on the basis of the dialects found in the current research in Maryland is to analyze from the linguistic point of view, at present, Lanzhou dialect of more in-depth study of linguistics, but from the perspective of the analysis of ics not a lot, in the light of these circumstances, I have chosen for the study of Lanzhou dialect. Secondly, access to information based on bination of Lanzhou dialect and Putonghua Phonology transfer between the differences in the design of the text corpus, the corpus contains 280 words, 2000 two-syllable words and 30 sentences, and the corpus of these texts Maryland conducted a parallel dialect and Putonghua Corpus voice recording, a corpus of speech segmentation, tagging, the corpus can be used for analysis, synthesis. Finally, the corpus of speech carried out a detailed analysis of the contents of the main characters including the two-group analysis of the value of fundamental frequency, as well as the occurrence of two-binations in the case of continuous tone. In the two-binations, some have maintained the value of fundamental frequency of the fundamental frequency the same word, while others change tune a new type of transfer value, which will provide the basis for conversion, the basis for synthesis.
