语音分析的能量算子方法

Speech analysis by the method of the energy operator

用能量算子方法来分析语音信号的幅度包络和瞬时频率，并在此基础上设计了一种基于能量算子的基音检测方法。

The Energy Operator is one kind of signal analysis method developed in recent years, which can be used in processing oscillatory signals that have both amplitude modulation (AM) and frequency modulation (FM) structures. The speech signal can be modeled as a sum of AM FM signals. The application of the Energy Operator to the analysis of the envelope and instantaneous frequency of a speech signal is presented in this paper, and a pitch detection algorithm based on it is designed with a good result.
