The analysis of a speech signal with the help of procedure of reconstruction of mathematical model of speech process on a produced speech signal

The results of a return filtration of a speech signal were investigated. The model of speech process with the help of procedure of reconstruction of mathematical model of dynamic system on a produced temporary number (line) is received, as which use a speech signal. The factors of the submitted model were used for a return filtration of a speech signal and can be used for identification and verification of the announcer on a vote. The received estimation of derivative volumetric speed of an air flow through a voice crack integrates for reception of an estimation of volumetric speed of a flow. The volumetric speed after a return filtration was compared to the calculated volumetric speed on known model. The received results of a return filtration were compared to the help of reconstruction of mathematical model of dynamic system on a produced temporary number (line) with results of a return filtration with the help of model of a linear prediction by the value of everege quadro error.
