| 摘 要： | 通过对飞机座舱环境下语音信号特征的分析，提出了一种根据噪声分类逐类进行语音增强，然后依一定次序级联各类算法的语音增强方法，并讨论了级联次序对增强效果的影响。在分别实现脉冲噪声、周期噪声和宽带噪声消除算法的基础上，依据此方法开发了基于MATLAB计算环境的交互式语音增强系统，并利用该平台进行多种算法的级联实验，取得了良好的语音增强效果。

| Abstract: | Through the analysis of the characteristics of speech signals and noises in the cockpit,a new speech enhancement method which can be called "arithmetic joining" is proposed based on the separate enhancement against classified noise,and the effect of the "arithmetic joining" order is also discussed in detail. Based on the separate reduction of pulse noise,periodic noise and broadband noise,an interactive speech enhancement system is developed in MATLAB GUI Builder using the M program language of MATLAB.
