Abstract :
Speech is assumed that its production come from some different vocal sources. Regarding the Chinese mandarin phonemes, based on the independent component analysis, we separate its temporal independent components from a specific phoneme and discuss the formants, fundamental frequency F0, linear predictive coding (LPC) spectrum and Wigner-Ville (WV) spectrum of every independent component. Based on the LPC and Wigner-Ville spectrum windowed in the formants position, the different timbre phoneme is synthesized. Our analysis is proved to be effective by the experimental results.
