| 摘 要： | 设计提出了一种多参数的清/浊音判决法。该方法是在传统两参数(短时能量和过零率)算法基础上增加了自相关函数和短时平均幅度作为判决参数,并通过对短时能量、平均幅度、短时过零率曲线等参数的分析和计算,来达到减少清/浊音信号的误判率的目的。经实验证明,算法切实可行,且误判概率小。

| Abstract: | This design presents a method of voicing decision based on multiple parameters.Based on the traditional two-para meters (short-term energy and zero-crossing rate) algorithm,it involves self-relation function and short-term average range as decision parameters.By analyzing and calculating the short-time energy,the average rate,the short-time zero-crossing rate curve and other related parameters,it can achieve the goal of reducing the rate of unvoiced/voiced misjudyment.Simulation results show that this metho... |
