语音信号处理中基频提取算法综述

A Summarize of Pitch Detection Algorithmic in Speech Signals Processing

基频提取在语音信号处理领域是一个基础的课题。经过多年的研究,现在的技术在准确率和鲁棒性方面还没有达到一个十分令人满意的水平。当语音是一个干净的语音时,大部分的基频提取算法的结果都很好,但是当语音中混有较强的噪声,或者语音是多个语音的混合,从而同时含有多个基频的时候,很多现在的技术都表现得不好。该文介绍了若干主要的基频提取算法,并对这些算法的改进进行了讨论。

Pitch detection is a basic topic in speech signals processing. Through many years’ research, there is yet a satisfied technology in terms of accuracy and robust. When the speech is clean, most of the pitch detection algorithms are fine, but many technologies are not satisfied when the speech mixed with noise or the speech is a mixture of multi-speech. This paper introduces some mainstream pitch detection algorithms, and discusses the improvement of these algorithms.
