| 摘 要： | 本文提出了一种新的语音信号的基音周期检测方法,该方法根据语音信号的三阶累积量去确定语音信号的基音周期,能有效地排除白色或有色的高斯加性噪声所带来的干扰.与传统的基音周期估计的自相关函数法或平均幅度差函数法(AMDF)相比,该方法更精确、有效,具有更强的鲁棒性.

| Abstract: | We propose a new pitch detection method of speech signal in this paper. Based on the third-order cumulant this method can effectively eliminate the disturbance of additive white or colored Gaussian noise. Compared with the conventional pitch detection methods based on autocorrelation functions or average magnitude difference functions (AMDF), our method is more precise and effective, and is more robust versus additive colored Gaussian noise. |
