| Abstract: |
Existing methods that obtain the vocal-tract area functions (VTAFs) from the vocal-tract filters (VTFs) using speech signals suffer from inadequate elimination of the glottal wave and the influence of non-ideal vocal-tract boundary conditions. To minimize these effect on the VTF estimation, we present a method that jointly estimates the glottal wave and the VTF corresponding to closed glottal phases. Experimental results show that our method yields better estimates. The VTAFs obtained for /a/ and /i/ each produced by a female and a male subject show that more detailed and accurate VTAFs are obtained using the speech signals corresponding to closed glottal phases. |
