汉语普通话音高模式在话者鉴别中的应用

Research on the application of Mandarin Chinese pitch patterns in speaker identification

汉语普通话是声调语言,不同话者在基频水平和声调变化规律方面存在差异。本文利用常规软件分析不同话者的基频数据变化规律,经过归一化和多次曲线拟合后,形成具有明显形态特征的音高模式曲线。通过比对分析音高模式曲线的形态和模式参数差异,可以帮助实现话者鉴别的目的 。

Chinese is tone language;there are differences on pitch level and change of tone between speakers.In this paper,general software was used to analyze the change of pitch data from different speakers,and pitch patterns curves with apparent morphological features were established after pitch data being normalized and fitting.We could identify speaker through analyzing the differences on the form of pitch patterns and parameters.
