摘要
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．
In this pape we succeeded in applying fractal theoretics to the analysis of Mandarin speech.The rules of the fractal dimension distribution of Mandarin speech have been obatined by computing and statistically analyzing the Box Dimension of 21 kinds of consonant and 38 kinds of vowel of Mandarin speech. The preliminary results show that Mandarin show that Mandarin speech has the scale-invariant property and the BOx dimersion can indi cate the complexity and irregularity degree of waveform of Mandarin speech. The novel discoveries in our studies imply that fractal theoretics have great prtentials in the field of speech signal processing.
