| 摘 要： | 提出了一种数字形态滤波与数字低通滤波器相结合作为基音检测预处理的基音检测新方法，本方法是线性滤波与非线性滤波相结合的一种新的尝试。实验结果表明，该方法可以得到比传统自相关法和倒谱法更好的结果，尤其是清浊音特征不明显的音段，基音检测的性能更好。

| Abstract: | We propose a new method of pitch detection, which combined of morphological filter and conventional linear band pass filter. The results show that the new method performance is better than the conventional autocorrelation algorithm and cepstrum method, especially in the part that the surd and the sonant are not evident. |
