本文旨在将新兴的混沌、分形理论引入语音信号处理。本文提出了一种新的语音信号相空间重构方法，分析、统计了语音信号最大Ｌｙａｐｕｎｏｖ指数及分维度的分布，并提出了基于分形码本的语音信号码激励线性预测编码新算法。本文的研究表明，混沌、分形理论在语音信号处理中有良好的应用前景。
The purpose of this paper is to introduce emerging chaos, fractal theory into speech signal processing. In this paper, a new phase space reconstruction method for speech signal is proposed. The maximum Lyapunov exponent and the distribution of fractal dimension of speech signal are analyzed and calculated. A novel speech coder linear predictive coding algorithm based on fractal codebook is proposed. The research in this paper shows that chaos and fractal theory have good application prospects in speech signal processing.
