Detection of speech modulated transmissions, to provide an automatic classification, involves standardizing average energy and forming average phoneme period |
摘要 |
The system has a preprocessing stage that filters the incoming signal that eliminates phase distortion before being subjected to a process that standardizes the signals to have the same average energy. The process analyses the instantaneity of the signals and the short time base energy forms the average phoneme period of the speech signals.
