语音增强是影响语音识别系统性能的重要成分。为了比较语音增强算法的性能,采用Matlab软件进行了数值仿真,对不同噪声环境下的语音用3种不同的方法进行降噪,采用信噪比、端点检测等方法来降噪效果,并对几种增强算法的性能进行了比较分析。结果表明,在变噪声环境下短时谱MMSE法最佳,谱减法和维纳滤波法各有优点。-Speech enhancement of voice recognition is an important component of system performance. In order

实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器,再对输入带噪信号进行滤波;第二步是在此基础上的改进,用了自适应的思想,及时根据当前帧的状态更新修正滤波器的系统函数,得到更精确的无噪语音信号。第三步是采用自适应LMS方法,在时域迭代计算滤波器系数,迭代次数足够多时可得到较准确的有用信号。-Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtai
