本文应用分形理论来研究汉语普通话语音的分形特性．通过计算和统计分析汉语男女声２１种声母和３８种的母语音信号时域波形的分形盒维数，得到了汉语语在信号分形维数在维数空间上的分布规律．实验结果表明，汉语语音信号具有分形标度不变性，分形维数能够反映语音信号时域波形的复杂程度．
This paper uses fractal theory to study the fractal characteristics of Chinese Mandarin. Through the calculation and statistical analysis of fractal box dimension of 21 kinds of Chinese consonants and 38 kinds of mother speech signals in time domain waveform, the distribution law of Chinese language in dimensionality of signal fractal dimension is obtained. Experimental results show that the Chinese speech signal has the invariance of the fractal scale, and the fractal dimension can reflect the complexity of the waveform of the speech signal in the time domain.
