| Abstract(in English) | We are developing a speech analysis method based on the Glottal-ARMAX (A__-uto R__-egressive and M__-oving A__-verage eX__-ogenous) model, in which the speech production model is supposed to an ARMAX vocal tract model with two kinds of inputs: glottal source model excitation and white Gaussian. The speech analysis method based on the Glottal-ARMAX model can estimate the glottal source model parameters and ARMAX model parameters simultaneously. In this report, we introduce subband procedure with a QMF filterbank and filterbank with Haar basis to the Glottal-ARMAX method in order to reduce the computational effort. The introduction can reduce computation since the orders of ARMAX identification can be set smaller than those of full-band analysis. The introduction also makes it possible to improve the estimation accuracy of glottal source model parameters owing to the improved resolution in the frequency-domain. |
