【Abstract】 Wavelet analysis has advanced rapidly in recent years, it applies diversely to digital com- munication and compuer image manipuation. Now wavelet analysis based on strictness and perfect of math applies not only to academic research but also to resolution of practical prohlems. This paper analyzes the implementation of wavelet transfOrm in keynote period picking of speech signal and its settlement scheme.更多还原
