| 摘 要： | 依据数字语音信号的特点和形态滤波器的基本特征，合理选择结构元素构筑了一组用于汉语语音基音轨迹平滑的形态学滤波器，这是继中值滤波和动态规划后一种新的非线性基音轨迹平滑算法．仿真数据的实验结果表明这种方法对于随机误判点与传统中值组合平滑相比效果更佳． |

| Abstract: | In the light of traits of digital speech signal and properties of morphological filter, a new morphology filter with suitable structuring element, is proposed, which is designed to apply to getting accurate pitch contrail of speech or mandarin. This is a new non-linear algorithm for pitch contrail smoothing following the traditional methods of median smoothing and dynamic programming. Simulation results show that this new approach is better than the conventional median filter on the stochastic incorrect value. |
| Keywords: | speech signal morphological filter structuring element pitch contrail smoothing non-linear |
