在本文中，各种基音周期确定方法和算法（PDA）分为两大类：时域PDA和短期分析PDA。短期分析PDA通过短期变换离开信号域。它们提供来自连续帧的平均音高估计序列。个体算法的特征在于其应用的短期变换。另一方面，时域方法逐周期地跟踪信号。本文首先简要介绍了PDA的基本原理，然后讨论了PDA在语音学、教育、语音学和语音通信系统中的应用前景。
In this paper, the various pitch determination methods and algorithms (PDAs) are grouped into two major classes: time-domain PDAs and short-term analysis PDAs. The short-term analysis PDAs leave the signal domain by a short-term transformation. They supply a sequence of average pitch estimates from consecutive frames. The individual algorithm is characterized by the short-term transform it applies. The time-domain methods, on the other hand, track the signal period by period. Extraction and isolation of the fundamental harmonic, and investigation of the temporal signal structure are the two extremes between which most of these PDAs are found. After a short review of these principles, the paper finally discusses different application-oriented aspects, i.e. the role of the PDA in phonetics, education, phoniatrics, and speech communication systems.
