LPC在非基音同步情况下是一种有偏估计算法
用于共振峰参数估计时误差较大。同态线性预溯编码(HLPC)算法在任何情况下都是无偏的。本文定量研究了不同条件下两种算法的共振峰参数估计精度
实验证实
任何情况下HLPC算法的估计精度都优于或远优于LPC算法。
LPC gives biased estimation when analysis is pitch-asynchronous
so that the errors of formant parameter estimation of LPC are large.Homomorphic Linear Prediction Coding (HLPC) gives unbiased estimation in any case.The accuracy of formant estimation for both algorithms under various condition is studied quantitatively in this paper. The results show that
the accuracy of HLPC estimation is better or much better than LPC estimation in any case.
