A lowpass filtering step is carried out and a DFT on the squared amplitude is then performed to transform the LPC residual samples into another domain. An initial pitch lag can then be found with lower resolution. After getting the low-resolution pitch lag estimate, a refinement algorithm is ...
激励信号 e(k)经过一个时变的全极点滤波器产生,全极点滤波器的系数取决于所产生的特定声音的声道形状。生成语音信号 s(k)可以表示为 s(k)=\sum_{p=1}^P a_p s(k-p)+e(k)其中,P是滤波器的阶数, a_p是滤波器的系…
Linear Predictive Coding Pole Processing (LPCPP)是一种参数化的时频方法,可用于实时识别和跟踪信号中主导频率成分的变化。该方法的实时性指的是离散信号的每个采样瞬间。LPCPP方法进一步处理LPC(线性预测编码)极点,以产生一系列降阶滤波器传递函数来实现主导频率估计。LPCPP是一种基于线性预测编码原理的方法,它通过...
