A Practical Look-back and Look-forth Pitch Tracking and Smoothing Algorithm
Dusheng Wang, Lizhong Li, Jian‐Kang Zhang · 2006
This paper presents a simple practical look-back and look-forth pitch tracking and smoothing algorithm based on dynamic programming approach. The experimental results show that this tracking and smoothing algorithm can improve the accuracy of pitch estimation when it is incorporated into the multiband excitation time domain autocorrelation pitch estimation
