| 中文摘要: |
| 针对语音信号的特点，清音和浊音，清音没有明显的周期性，它类似于高斯白噪声，浊音具有周期性的特征，并且浊音的基音周期只有准周期的特点，另外语音信号是非线性时变的信号，只能采用短时平均方法估计基音周期。针对这些特点，本文对处理的语音信号按照频率进行分组，分组后再进行基音周期的提取，减少了处理的复杂度和增加了准确率 |
| 英文摘要: |
| In this paper, according to the features of speech signals, speech and voiced, unvoiced speech has no obvious periodicity, which is similar to the Gauss white noise, character voiced with pe- riodic, pitch and voicing only quasi-periodic characteristics, the speech signal is nonlinear and time-va- rying, only using the short time average method of pitch estimation. According to these characteris- tics, the speech signal processing are grouped according to the frequency, packet after extraction of pitch period, reduce the processing complexity and increases the accuracy rate |
