摘要
对三种不同方言同一语句的语音资料进行了频谱分析与比较,利用Praat软件提取了三种方言的基音周期、基音周期内的频率加权平均、共振峰平均值。构建了三个方言特征矩阵,通过对三个方言特征矩阵的特征值与特征向量的数值分析,揭示了方言在一个方言区内随地域变化的内在规律,这种方法可用于方言的说话人识别。
In this paper three different dialects of the same phrase for the voice data of spectrum analysis and comparison,we extract the three dialects of the pitch period,the frequency-weighted average in pitch period and the first formant average by using the software Praat and construct the three dialects of characteristic phalanx. Through the three dialects of the matrix eigenvalue and eigenvector of mathematical analysis,reveals the inherent law of dialects with the geographical changes in a dialect region.
