摘要

本文运用动态规划技术，提出了一种实用的双向跟踪基音周期平滑算法．实验结果表明，在用多带激励时域自相关法估计基音周期时，结合该算法对基音周期进行双向跟踪平滑处理，可显著提高基音周期估计的准确度

Abstract

This paper presents a simple practical look back and look ahead pitch tracking algorithm based on dynamic programming approach.The experimental results show that through the multi band excitation time domain correlation pitch estimation

this smoothing algorithm can improve the accuracy of pitch estimation.
