摘　　要：文章给出了一种用Matlab实现Bark子波的方法。引入子波基函数与实际频率的关系,介绍了Bark子波的定义和数学性质,结合Matlab进行算法实现并进行了仿真实验,结果表明Bark子波对语音信号具有很好的重构性能。A method to implement Bark wavelet using Matlab is proposed in the article. It introduces the relation between wavelet base function and actual frequency and clarifies the definition and mathematics characteristics of Bark wavelet as well. In addition, it makes arithmetic realization combining with Matlab and carries out simulation experiment, whose result indicates that Bark wavelet provides the good reconstructive capability for speech signal.
