| Abstract(in English) | In the spectrum analysis of speech,a few pitches data has been regarded as a stationary process in long time.However,this point of view see only an average vocal-tract transfer characteristic of vowels.We proposed the MSLP method with the Fejer kernel for the short-time analysis.We consider the ability of our method,the influence of quantization error caused by power variation in a pitch,and estimate time-varying spectra of isolated vowels in which the variation is shown in the different intonation for the glottal closure.In addition,we compare the tendency of variations in formant frequency and band width for the computed spectra. |
