[matlabqingzhuoyin

Description: 本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数(短时能量和过零率)算法基础上增加了自相关函数作为判决参数,减少了清/浊音信号误判率。-This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.
