| Abstract: | The developing process and basic concept of speech signal processing are introduced. According to the method of short time divided form numbers fuzzy control filter, the noise in the speech signal is filtered. The new algorithm of network divided form numbers and short time divided form numbers is pointed out. The choice algorithm of fuzzy control parameter in the filter method of fuzzy control is discussed. Speech signal is simulated on the workbench of virtual instrument(VI) LabVIEW 7.0 software. |
