【Abstract】 Based on the properties of envelop filters and the characteristics of speech digital signals, two fast envelop extracting algorithms for speech signals are proposed in this paper. The complexity of computation and the error performances of these novel algorithms proposed are discussed. The simulation resluts show that the algorithms are efficient for extracting the envelop of speech signals.更多还原
