摘要

根据语音发声和传播过程中表现出的混沌特性

首先验证了富含不同情感的语音信号是具有混沌特性的.其次采用非线性动力学理论提取了基于情感语音信号混沌特性的的3种非线性特征: 最小时间延迟、关联维数和最大Lyapunov指数.最后

设计了不同的实验验证了非线性特征的识别性能.实验中选用了Berlin语音库中的情感语句.采用了支持向量机进行了情感识别

其中参数采用十倍交叉验证获得.最后

对不同的实验结果进行了归纳分析

对比了不同非线性特征用于识别基本情感时的优劣.

Abstract

Based on the chaotic characteristics of speech utterance and propagation

the experiment firstly verifies that speech signals with different emotions have chaotic characteristics. Secondly

the experiment tries to adopt the nonlinear dynamics theory to extract three kinds of nonlinear characteristics which are based emotional speech signal. The characteristics include the minimum time delay

correlation dimension and Lyapunov exponent. Thirdly

designed different experiments to verify the recognition performance of the non-linear characteristics. Furthermore

the experiments have selected emotional statement from Berlin speech database and have used a support vector machine to identify the emotion. And the parameters are obtained by ten-fold cross-validation. Finally

through the summarizes and analyzes of the experimental results from different experiments. Then it compares the relative merits of different nonlinear characteristics which were used to identify the basic emotions.
