| Abstract: | 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. |
