摘要

本文提出了一种新的离散分数阶余弦变换方法,利用主谐波对含噪语音进行基音估计。其基本思想是对语音信号进行离散分数阶余弦变换预处理,然后利用整流后的优势谐波进行信号重构。利用Keele基音提取参考数据库对该方法进行了性能测试,并与现有方法进行了比较。对比结果表明,该方法在基音粗误差和基音细误差检测精度上均优于现有方法。

Minimization of Error in Pitch Detection algorithm using Discrete Fractional Cosine Transform
A novel Discrete Fractional Cosine Transform implementation for pitch estimation of noisy speech using dominant harmonic is introduced in this paper. The basic idea is to preprocess the speech signal with discrete fractional cosine transform before using the rectified dominant harmonic for signal reshaping. The performance of the proposed method is tested and compared with the latest previous method using Keele pitch extraction reference database. Comparative results show that the proposed method can detect pitch with better accuracy in terms of gross and fine pitch error as compared to the latest technique.
