Abstract :In this paper, a nıultiresolutional analysis/synthesis algorithm is introduced for the time-scale modification insert ignore into journalissuearticles values(TSM); of speedı sigpals. Unlike most time domain methods, this algorithm modifies the wavelet coefficients of the speech sigııal instead of modifying the speech waveform itself. In this method the speech signal is fırst divided into its subbands in order to obtain more accurately localized temporal and freqtıency information for the TSM algorithm.
