| Abstract(in English) | In this report,an estimation accuracy of an extended MIS using a time-varying ARMA-D model is explored.The synthesized speech waveforms are generated from a time-varying AR model or ARMA model whose input is Rosenberg wave in this experiment.It is shown from the experiment that the extended MIS yields more accurate spectra than RLS and MIS.For real speech waveforms,the tracking ability is discussed from the viewpoint of the variation of the innovations. It is shown that the extended MIS has higher performance than the others.Moreover,it is also obtained from the other experiments that the spectra by the extended MIS are the almost same as the spectral envelopes of DFT with adequate window length. |
